Modern Kitchen Cooking Techniques Guide

Science-backed, nutrient-conscious techniques for triply pans, LPG, a 36 L OTG, microwave, pressure cooker and stand mixer. Review copy exported 9 Oct 2026 from the live doc. Units: °C, grams, ml.

Before any technique, measure what your own equipment actually does: a dial that says 180 °C and a burner marked "high" are guesses until tested. These tests take about two hours in total, need only water, bread, flour and a probe thermometer, and every later page refers back to the numbers you record here. Units: °C, grams, ml.

1.1 Calibration tests

Run these eight tests in order: the thermometer and scale come first because every other test depends on them. Three tests use the same physics: 1 g of water needs 4.186 J to warm by 1 °C, so timing how fast a known mass of water heats measures the real power reaching the food.

Test 1 — Probe thermometer (10 min)

1. Fill a glass with crushed ice, top up with cold water, stir for 1 min. Probe in the middle, not touching the glass: it should read 0 °C.
2. Bring water to a rolling boil and probe it. It should read your local boiling point, about 100 − (altitude in m ÷ 300) °C, e.g. about 95.5 °C at 1,370 m.
3. Note the offset; recalibrate if the probe allows, otherwise add or subtract it in your head.

Test 2 — Kitchen scale (2 min)

Tare a jug, pour in 500 ml of water measured in a measuring jug; the scale should read 500 g ± 5 g. This also tells you how accurate your measuring jug is. From here on, weigh flour, rice, dal and sugar rather than using cups.

Test 3 — Oven: true temperature and hot spots (90 min)

OTG dials are commonly 10–30 °C off, and a small cavity swings above and below the set point as elements cycle.

1. Hang an oven thermometer at the centre of the middle rack.
2. Set 180 °C, fan on. Record the time until the thermometer stabilises (preheat time), then read every 2 min for 10 min: lowest, highest, average.
3. Repeat at 150, 200 and 230 °C, and once at 180 °C with the fan off (fan-off runs cooler at the food surface; recipes written for fan ovens, like Bertinet's, assume fan on).
4. Toast map: cover the middle rack with bread slices, 180 °C fan on, 8–10 min. Photograph it. Dark slices mark hot spots; rotate trays halfway through bakes accordingly.
5. Shelf bias: repeat the toast map on the top shelf to see how strongly the top element browns.

Test 4 — LPG burners: real power (30 min)

1. Put 1,000 g of water at about 20 °C into your most-used 20–24 cm triply pan, lid on.
2. Burner on full. Time it from the start temperature to 80 °C (stop below boiling so altitude does not matter).
3. Effective power in watts ≈ 4186 × (80 − start temp) ÷ seconds. Example: 20 → 80 °C in 180 s ≈ 1,400 W.
4. Repeat for each burner, and once on the lowest (sim) setting of the small burner for 5 min to know your gentlest heat.

Test 5 — Triply pan preheat for searing (10 min)

Triply needs a properly hot surface before fat goes in, or protein bonds to the steel and sticks.

1. Dry pan on the medium burner at medium flame. Every 30 s flick in a few drops of water.
2. At first drops sizzle and evaporate. When a drop forms a single ball that skates across the pan (the Leidenfrost effect, surface about 190–200 °C), the pan is ready. The vapor layer physically separates the protein from the steel matrix, preventing sticking: add oil, then food.
3. Record the time and flame setting. Too hot: the oil smokes at once; take the pan off for 30 s.

Test 6 — Microwave power (5 min)

Packaging and many recipes assume a stated wattage; the real figure falls with age.

1. Weigh 1,000 g of tap water into a microwave-safe glass jug. Stir and record the temperature.
2. Heat on full power for exactly 60 s, stir, record again.
3. Power (W) ≈ 70 × temperature rise. A 12 °C rise ≈ 840 W. (The jug absorbs a little heat, so this reads 5–10% low, which is close enough.)
4. Repeat at 50% power to see whether it pulses or truly runs at half.

Test 7 — Pressure cooker: whistles to minutes (40 min)

Whistle counts vary with flame, fill level and cooker, so the guide gives times at pressure. Check the gasket and that the vent is clear first.

1. Water test: 1,000 ml water, lid on, large burner on full. Record the time to the first whistle and the gap between whistles 1→2 and 2→3. Release naturally.
2. Benchmark dal: 200 g toor dal (rinsed, unsoaked) + 600 ml water + ¼ tsp turmeric. Full flame to the first whistle, then lowest flame for 8 min, then release naturally. Check: fully soft and mashable? If not, repeat next time with 10 or 12 min on low.
3. Your standard from now on: "first whistle, then X min on low, natural release."

Test 8 — Stand mixer: dough temperature and kneading time (30 min + bake)

Yeast dough ferments best at a final dough temperature of 24–26 °C. A mixer adds heat by friction, so measure how much yours adds.

1. Make a lean dough: 500 g bread flour, 350 g water, 10 g salt, 7 g instant yeast (70% hydration). Record flour, room and water temperatures.
2. Mix on speed 1 for 2 min, then speed 2 until the dough passes the windowpane test (stretch a piece thin enough to see light through without tearing). Record the minutes.
3. Probe the dough. Friction factor = 3 × dough temp − (flour + room + water temps).
4. Next time, water temperature = 3 × 25 − (flour + room + friction factor).

1.2 Measuring and doneness

Weigh dry ingredients and judge doneness by core temperature; cup volumes of flour vary by 20% or more depending on how the cup is filled. Use cups and spoons only for small amounts of spices and liquids.

Proteins set at characteristic temperatures, so a probe reading tells you both safety and texture. Pull roasts and steaks 2–5 °C below target: heat stored in the outer layers keeps cooking the centre while the meat rests (carry-over), more for large roasts than for thin cuts.

1.3 Food safety

Leaving cooked food warm causes most home food poisoning. Bacteria multiply fastest between 5 and 60 °C; move cooked food through that range quickly in both directions.

• Cool fast. Get leftovers into the fridge within 1–2 hours. Spread rice, dal and curries into shallow containers; a deep pot stays warm in the centre for hours. Fridge at 5 °C or below, freezer at −18 °C.
• Rice needs extra care. Bacillus cereus spores survive cooking and their toxin is not destroyed by reheating. Cool cooked rice within 1 hour, eat within 24 hours, reheat once only, to steaming hot.
• Reheat once, to 75 °C throughout. In the microwave, cover, stir halfway, then let it stand 1–2 min so heat evens out, and probe the centre.
• Rajma and other kidney beans: soak, discard the water, and boil hard (or pressure cook) to destroy the lectin phytohaemagglutinin. Slow cooking at around 80 °C can make raw kidney beans more toxic, and at altitude an open pan boils below 100 °C, so use the pressure cooker.
• Raw and cooked apart. Separate boards for raw meat and fish; wash hands and boards with hot soapy water after.
• Thaw safely: in the fridge overnight, or in the microwave on defrost and cook at once. Never on the counter.
• Frying oil: strain after use and store covered. Reuse at most two or three times, and discard sooner if it is dark, thick, foams, or smokes at normal frying temperature; degraded oil forms polar compounds linked to health risks.
• Pressure cooker: fill to no more than two-thirds (half for pulses and grains, which foam), keep the vent and gasket clean, and never force the lid open.

1.4 Altitude adjustments

Above about 900 m, lower air pressure drops water's boiling point by roughly 1 °C per 300 m, about 95.5 °C at 1,370 m. Anything cooked in water or steam cooks more slowly, water evaporates faster, and gases expand more in baking. Use your Test 1 boiling reading as your local figure.

Six mechanisms control every technique: heat transfer, browning, protein denaturation, starch gelatinisation, and nutrient degradation. Each technique page links back here. Sources are the two textbooks in the filtered collection (Science of Cooking, Provost et al. 2016; Chemistry of Cooking, Rodriguez-Velazquez 2016) and the Iowa State lab manual.

2.1 Heat transfer

Heat reaches food in four ways, and each of your tools relies on one or two of them. The medium matters as much as the temperature: water conducts heat about 23 times better than air, which is why you can put your hand in a 200 °C oven for a moment but not in 100 °C water.

Three consequences used throughout the guide

1. Thickness controls time. Heat penetrates from outside in; doubling thickness roughly quadruples the time for the centre to reach temperature. That's why the guide cuts to even sizes and uses a probe.
2. Carry-over cooking. The hot outside keeps feeding heat inward after cooking stops; pull roasts and steaks 2–5 °C early (Part 1.2).
3. Water caps temperature. Anything wet stays at or below boiling point (about 95 °C at 1,370 m) until it dries. Browning needs a dry surface; altitude slows anything cooked in water (Part 1.4).

2.2 Browning

Two different reactions make food brown and flavourful; most dishes use both.

(Science of Cooking ch. 6, Table 6.3)

What speeds browning (and how the guide uses it)

• Dry surfaces: water must evaporate first, so pat food dry and don't crowd the pan (5.1, 5.2).
• Higher pH (alkaline): browning runs several times faster above pH 7. A pinch of baking soda speeds onion browning; pretzels and bagels are dipped in alkali for their dark crust. Acid (lemon, yogurt, tomato) slows browning, which is why masalas brown before the tomato goes in (Source notes: masala sequence).
• Sugar: honey, milk (lactose) or jaggery in a marinade or glaze browns faster; tandoori marinades with yogurt colour quickly.
• Time and temperature: low and long (onions over 15 min) gives deeper, sweeter flavour than fast and hot, which burns the outside first.

The limit: acrylamide and charring. Acrylamide forms when starchy foods (potatoes, bread, grains) are fried, roasted or baked above about 120 °C, from the amino acid asparagine and sugars. Its health effect at dietary levels is still uncertain (Science of Cooking ch. 6), but the sensible rule is to aim for golden rather than dark brown, soak or rinse cut potatoes, and don't store potatoes in the fridge (it raises their sugar). Charring meat forms heterocyclic amines and polycyclic aromatic hydrocarbons (5.1, 5.6).

2.3 Proteins

Heat unfolds (denatures) proteins, which then bond to each other (coagulate). That sets eggs, firms fish and meat, and curdles milk. Each protein has its own temperature, which is why the probe readings in Part 1.2 work.

Rules that follow

• Tender cuts: cook quickly to a low core temperature (sear, grill, roast to 52–63 °C). Tough cuts: cook long, wet and gently past 70 °C until collagen melts (braise, pressure cook, dum). The middle (well-done tender cuts, briefly cooked tough cuts) is the dry, chewy zone.
• Salt early or not at all. Salt dissolves some muscle proteins so meat holds more water; dry-salting 40 min to 24 h ahead (or brining) gives juicier meat. Salting just a few minutes before cooking draws out surface liquid and hinders browning.
• Acid and enzymes tenderise only the surface. Yogurt, lemon, raw papaya or pineapple act within a few millimetres; slashes help (Jaffrey's tandoori). Too long in strong acid or papain makes the surface mushy.
• Dairy curdles with heat plus acid or salt. Add yogurt a spoon at a time over moderate heat (Jaffrey), use full-fat yogurt, or stabilise it with a teaspoon of besan or cornflour.
• Rest meat 5–15 min so juices thicken slightly and the centre evens out.

(Science of Cooking ch. 8–9; Lab Manual ch. 7–11)

2.4 Starch and gluten

Starch is how plants store energy: tightly packed granules of amylose and amylopectin in rice, wheat, potatoes, dal and corn. Three things happen to it in cooking.

High-amylose starches (basmati, parboiled rice) cook into separate grains; high-amylopectin starches (sticky rice, arborio, waxy potatoes) turn creamy or sticky. Acid weakens starch thickening (add lemon at the end); sugar delays gelatinisation (sweet custards need longer). (Chemistry of Cooking ch. 14–18)

Gluten forms when wheat's two proteins, glutenin (strength, elasticity) and gliadin (stretch), meet water and are worked. Kneading lines the proteins up into an elastic network that traps gas, giving bread its rise and chew; heat then sets it (Chemistry of Cooking ch. 30).

Salt tightens gluten; fat and sugar shorten it; rest relaxes it, which makes rolling easier. Rye, millets, besan and rice have little or no gluten, so their breads rely on gums, starch and fermentation instead.

2.5 Nutrient conservation

Four mechanisms destroy nutrients: leaching into cooking water, heat breaking them down, oxygen after cutting, and light in storage. Minerals and fibre are never destroyed by cooking, only drained away. Some compounds become more available with cooking. The rule of thumb: less water, less time, bigger pieces, cut just before cooking, and keep the liquid.

Method ranking for water-soluble vitamins (most kept to least): raw > microwave with little water ≈ steaming ≈ pressure cooking > quick stir-fry > roasting > boiling and draining > long stewing with liquid discarded. Stewing scores well when you eat the liquid (dal, curries, soups).

Storage and prep: buy fresh, store greens cold and humid, cut close to cooking, don't soak cut vegetables for long (except potatoes, for acrylamide), and avoid reheating vegetables repeatedly. (Lab Manual 3.2–3.3; Science of Cooking ch. 7)

2.6 Antinutrients, fats and unprocessing

Antinutrients are natural plant compounds that reduce mineral absorption or upset digestion. Traditional Indian methods already handle them well.

Fats in cooking

• Use fat for function: browning, carrying spice flavour (5.3) and absorbing fat-soluble vitamins. A tablespoon per dish is often enough; generous oil in a masala can be spooned off after cooking (Jaffrey).
• Stability over smoke point: fats high in saturated or monounsaturated fatty acids (ghee, groundnut, olive, rice bran) handle high heat and repeated frying better than polyunsaturated oils (sunflower, soybean). Use a mix of fats across the week.
• Don't reuse frying oil many times; discard dark, thick or smoking oil (Part 1.3, 5.4).

Unprocessing (Chatterjee, Spector): ultra-processed foods are industrial formulations with ingredients you wouldn't use at home (emulsifiers, flavourings, modified starches). Both doctors link them to overeating and poorer health; Chatterjee notes that more than half of UK food intake is ultra-processed. The practical answer is the rest of this guide: cooking from whole ingredients, batch-making staples (tomato masala, dahi, paneer, ghee, idli batter, stocks), and reading labels for what you do buy. Spector's "food matrix" point also applies: a whole orange or whole grain behaves differently in the body from its juice or refined flour, because fibre and structure slow digestion.

The preparations every cuisine builds on: cutting and organising, stocks, thickening, emulsions and handling spices. French cooking calls stocks and mother sauces its fonds (foundations); Indian cooking's equivalent is the paste, the masala and the spice blend.

3.1 Knife skills and mise en place

What it does: cutting to even sizes makes food cook evenly (2.1); having everything measured and ready before the heat goes on keeps fast techniques (tadka, bhuna, stir-fry) from burning. Jaffrey: many Indian dishes are cooked "in one, flowing sweep" with no time to hunt for a spice (IC p. 20).

The science: a sharp knife cuts cleanly through cells; a blunt one crushes them, releasing juice and enzymes that brown fruit and vegetables faster and pungent compounds in onions that make you cry. Cutting meat across the grain shortens the fibres so it chews tender (Jaffrey, SBS p. 14).

Your equipment: a 20 cm chef's knife and a small paring knife, kept sharp (steel before each use, sharpen on a stone or service every few months); a heavy board on a damp cloth so it doesn't slide; small bowls (katoris) for mise en place; a bench scraper to move chopped food.

Basic cuts

Method: mise en place for a curry

1. Read the recipe through; list the stages (Source notes: masala sequence).
2. Wash, cut and measure everything; group by when it goes in: whole spices in one bowl, pastes in another, ground spices together, liquids last.
3. Keep anti-browning items under water: cut potatoes in cold water with lemon (Jaffrey, SBS p. 13).
4. Put the bowls in cooking order beside the stove before lighting the burner.

Safety and hygiene: curl your fingertips under (claw grip) and guide the knife with your knuckles; a sharp knife is safer than a blunt one because it doesn't slip; separate boards for raw meat (Part 1.3); wash hands after chillies (Jaffrey, SBS pp. 13, 258).

3.2 Stocks

What it does: extracts flavour, gelatin and minerals from bones and vegetables into water, giving soups, sauces, risotto and pullao their depth. Koffmann calls veal stock "the absolute foundation of French cooking".

The science: long, gentle simmering dissolves collagen from bones and joints into gelatin (2.3), which gives stock body; it sets to a jelly when cold. A rolling boil emulsifies fat and protein specks into the liquid and clouds it, so keep it at a bare simmer and skim. Roasting bones and vegetables first (brown stock) adds Maillard flavour and colour. Fish bones are delicate and turn bitter if simmered too long. (Science of Cooking ch. 8)

Your equipment: largest triply pot on the sim burner; OTG at 200 °C to roast bones for brown stock; pressure cooker to cut times to a third; fine sieve or muslin; freezer containers or ice-cube trays.

Four stocks compared (Koffmann unless noted)

Method: any stock

1. Start in cold water so proteins coagulate slowly and rise as scum you can skim.
2. Bring just to a simmer; skim; then hold at a bare tremble, never a rolling boil.
3. Don't salt (it concentrates when you reduce the stock later).
4. Strain through a fine sieve; cool fast (shallow containers, ice bath); refrigerate. Lift off the set fat.
5. Keeps 3–4 days in the fridge, 3 months frozen. Reduce by half for a concentrated cube to freeze.

Nutrient note: stock adds gelatin, some minerals and flavour that lets you use less salt and fat elsewhere. Bone broth's health claims are mostly unproven; its main value is culinary.

Cuisine examples: FR — veal stock for Bordelaise, chicken stock for coq au vin (Koffmann); IT — brodo for risotto (MPW uses 400 ml per 100 g rice); PL — rosół is a clear chicken broth served as soup (Wikibooks); IN — yakhni (spiced mutton stock) for pullao and biryani, paya (trotter soup).

Common faults

3.3 Thickening

What it does: turns thin liquids into sauces, gravies, soups and custards with body.

The science: liquids thicken in four ways (Chemistry of Cooking ch. 14–21): evaporation concentrates dissolved solids and gelatin (reduction); starch gelatinisation swells granules that trap water (roux, cornflour, besan; 2.4); protein coagulation sets egg yolks into a network (liaison, custard; 2.3); and suspended particles (puréed onion, nuts, vegetables) add body. Indian sauces rely on the last; Jaffrey: "Flour is almost never used as a thickener for Indian sauces"; onions, garlic, ginger, yogurt and tomatoes do the job instead (IC p. 20).

Thickeners compared

Nutrient note: reductions and vegetable-based thickeners add flavour without much fat; nut pastes add protein and good fats but are calorie-dense; roux and cream are the richest. Thickening with puréed vegetables or pulses adds fibre.

Common faults

3.4 Emulsions

What it does: holds fat and water, which normally separate, together as a smooth sauce: vinaigrette, mayonnaise, hollandaise, béarnaise, butter-finished pan sauces.

The science: whisking breaks fat into tiny droplets dispersed in a watery liquid (vinegar, lemon juice, the water in egg yolk). Emulsifiers sit at the boundary and keep the droplets apart: lecithin in egg yolk, mucilage in mustard, proteins in milk. Add fat slowly at first so each new droplet gets coated. Temperature matters: cold butter or oil won't disperse; too much heat scrambles yolks (above \~70 °C) or melts butter emulsions into grease. Koffmann: the cooked yolks and the butter must be at about the same temperature (Hollandaise notes).

Your equipment: balloon whisk; heatproof bowl over a triply pot of barely simmering water (bain-marie) for hollandaise; stand mixer or mixer-grinder for mayonnaise; probe thermometer.

Method: vinaigrette (Koffmann's French dressing)

Whisk 1 tbsp Dijon mustard with 1 tbsp red wine vinegar, salt and pepper; whisking constantly, pour in up to 100 ml light olive oil gradually until thick. The mustard holds it together; shake again before serving. Ratio for everyday dressings: 1 part acid to 3 parts oil.

Method: hollandaise (Koffmann, summarised)

1. Clarify 350 g butter: melt gently, skim the foam, pour off the golden fat and leave the milky liquid behind. Keep warm.
2. Reduce 1 finely diced shallot, 4 tbsp white wine vinegar and 100 ml white wine until almost no liquid remains; cool.
3. Cook the yolks: 6 yolks with half an eggshell of water per yolk, plus the reduction, whisked in a figure-of-eight over gently simmering water for 5–10 min until fluffy. Done when a trail drawn with the whisk closes slowly (too fast: undercooked; solid: overcooked).
4. Mount: off the heat, whisk in the warm clarified butter in a thin stream.
5. Season with salt, white pepper and a squeeze of lemon. Use at once; hold at about 60–65 °C in the bain-marie if needed.
6. Béarnaise: make a second reduction with chopped tarragon and stir it into the hollandaise. (With tomato it becomes Choron; with mint, Paloise.)

Method: mayonnaise

1 yolk, 1 tsp mustard, 1 tbsp lemon juice or vinegar, salt; whisk while adding 200–250 ml neutral oil drop by drop at first, then in a thin stream. Thin with a little water if too stiff. MPW flavours it with truffle for asparagus.

Monter au beurre: swirling cold butter into a reduced sauce off the heat makes a light emulsion with gloss (5.1).

Nutrient note: these are rich sauces; use them in small amounts. Vinaigrettes with olive oil help you absorb fat-soluble nutrients from salad vegetables.

Common faults

Safety: raw-yolk mayonnaise and lightly cooked hollandaise aren't fully pasteurised: use very fresh eggs, keep cold (mayonnaise) or warm (hollandaise) and use within the day; avoid for pregnant, elderly, very young or immunocompromised diners, or use pasteurised eggs.

3.5 Spice handling

What it does: gets the most flavour from spices by choosing whole or ground, raw, roasted or fried, and storing them so they don't fade. Jaffrey: the same spice yields different flavours depending on how it is used, and "herein lies the genius of Indian cooking" (IC p. 20).

The science: a spice's aroma lives in volatile oils sealed inside its cells. Grinding breaks the cells and exposes the oils to air, so ground spices lose aroma within months while whole spices keep for a year or more. Heat transforms the oils: dry-roasting creates nutty, toasted notes through Maillard reactions (2.2); frying in fat dissolves and carries them (5.3); simmering in liquid gives a gentler, rounder flavour. Light, heat and moisture all speed staling.

Your equipment: spice or coffee grinder (wipe it after use so coffee doesn't taste of cumin, Jaffrey); small triply pan or cast-iron pan for dry-roasting; mortar and pestle for small amounts and wet pastes; mixer-grinder wet jar for ginger–garlic–onion pastes; masala dabba for daily spices; labelled airtight jars in a dark cupboard for the rest.

Four ways to use a spice (cumin as the example)

Method: dry-roast and grind

1. Small heavy pan on medium heat, no oil, preheated.
2. Add whole seeds; shake or stir constantly until a shade or two darker and fragrant: cumin and coriander 1–2 min, fennel 1 min, saffron a few seconds.
3. Tip onto a plate at once (the pan keeps cooking them); cool completely.
4. Grind in small batches; store in a small, tightly lidded jar. Roasted whole seeds keep for months.

Buy whole or ground? (Jaffrey's advice, summarised)

Wet pastes: blend ginger, garlic, onion or fresh chilli with just enough water to turn the blades (Jaffrey uses 3–5 tbsp); fry the paste until the raw smell goes and it darkens (5.2). Ginger–garlic paste keeps 1 week in the fridge with a little oil and salt, or freeze in ice-cube trays.

Storage: label every jar (Jaffrey can't tell ground cumin from ground coriander without smelling them); cool, dry, dark cupboard away from the stove; use ground spices within 6 months and whole within 1–2 years. Store fresh coriander roots in water under a bag in the fridge; freeze curry leaves flat; keep fresh chillies wrapped in newspaper, unwashed (IC; SBS).

Nutrient note: spices are among the most polyphenol-dense foods and each counts toward Spector's 30 plants a week (9.5). Turmeric with black pepper and fat absorbs far better (2.5).

Common faults

Water and steam cap the food's surface temperature near boiling point (about 95 °C at 1,370 m; about 118 °C in the pressure cooker), so these methods cook gently and evenly but never brown on their own. Combination methods (braise, dum) brown first in fat, then finish in liquid. Each page follows the template in the Plan tab; calibration numbers refer to Part 1.

4.1 Boil, simmer, poach, blanch

What it does: cooks food evenly in water at a controlled temperature; the four differ only in how hot the water is and for how long.

The science: water transfers heat about 20 times faster than air at the same temperature, so even a gentle simmer cooks quickly. Proteins toughen when the water is too hot (meat fibres contract, eggs rubberise); starches and vegetable fibres need near-boiling heat to soften. Vegetable pigments react to cooking: chlorophyll dulls to olive with acid and long cooking; anthocyanins (red cabbage, beetroot) turn blue in alkaline water and stay red with acid; carotenoids (carrot, pumpkin) are stable and fat-soluble. (Science of Cooking ch. 7; Lab Manual 3.2–3.3)

Your equipment: largest triply pot on the large burner (Test 4) for blanching and pasta, so the water returns to the boil fast; the sim setting of the small burner for poaching; probe thermometer to learn what each looks like on your hob.

Method: blanch and refresh green vegetables

1. Bring at least 3 L water per 500 g vegetables to a rolling boil; salt 10 g/L.
2. Add vegetables in small batches so the boil barely stops.
3. Cook until bright and just tender: beans 2–3 min, broccoli florets 1–2 min, spinach 20–30 s.
4. Lift straight into ice water (or under cold running water) for the same time; drain well.

Method: poach chicken breast or fish

1. Cover with cold or warm stock/water seasoned with salt, aromatics.
2. Heat to 75–80 °C (barely trembling); hold until the core reaches 74 °C (chicken) or 55–63 °C (fish).
3. Rest 5 min in the liquid off the heat.

Nutrient note: vitamin C, folate and other B vitamins leach into water and break down with heat. Boiling broccoli for 5 min can lose a third or more of its vitamin C; steaming or microwaving with a splash of water loses far less. Keep pieces large, time short, water minimal, and use the liquid where you can (dal, soup, rice). Carotenoids in carrots and tomato become more available after cooking, especially with a little fat.

Cuisine examples: IN — blanched spinach for palak (Jaffrey, SBS p. 137); IT — pasta and blanched broccoli rabe; FR — poached eggs, haricots verts; PL — boiled potatoes with dill; breakfast — poached eggs.

Common faults

4.2 Steaming

What it does: cooks food in water vapour without immersing it, so texture stays intact and fewer nutrients leach out.

The science: condensing steam releases a large amount of latent heat (about 2,260 J per gram) onto the food surface, so steam heats faster than the same temperature of dry air, yet never above boiling point. Food never sits in water, so water-soluble vitamins are largely retained. Microwave "steaming" heats the water inside the food directly, with similar retention. (Science of Cooking ch. 7; SBS p. 18)

Your equipment

• Stovetop: triply pot with a steamer insert or a rack; water 2 cm below the food at a steady boil; lid on; keep a kettle hot to top up (Jaffrey, SBS p. 18).
• Pressure cooker without the whistle: the classic idli and dhokla steamer. Remove the weight so steam escapes freely; it then steams at atmospheric pressure.
• Microwave: vegetables in a covered glass dish with 2–3 tbsp water; full power, stir halfway, stand 1 min. Time scales with your Test 6 wattage.

Method: steamed vegetables

1. Cut into even pieces (florets 3–4 cm, carrots 5 mm coins).
2. Bring the water to a full boil first, then put the food in and cover.
3. Times: broccoli 4–5 min, green beans 5–7 min, carrots 6–8 min, potato chunks 12–15 min (add 10–20% at altitude).
4. Season after steaming: salt, lemon, a little ghee or olive oil, or a tarka (Part 5.3).

Method: idli (from fermented batter, Part 7.3)

1. Grease idli plates; fill each mould three-quarters.
2. Bring 2–3 cm water to a boil in the pressure cooker; stack the plates in; lid on, weight removed.
3. Steam on medium-high 10–12 min; a skewer comes out clean.
4. Rest 2 min before unmoulding with a wet spoon.

Microwave times (800 W; scale by 800 ÷ your wattage)

Nutrient note: steaming and microwaving retain the most vitamin C and folate of the water methods. Steamed broccoli also keeps more of its glucosinolates (beneficial sulphur compounds) than boiled broccoli.

Cuisine examples: IN — idli, dhokla, momos, steamed fish in banana leaf (patra ni machhi); IT/FR — steamed mussels (moules), vegetables à la vapeur; PL — steamed pierogi or dumplings (pierogi na parze); breakfast — idli.

Common faults

Safety: open the lid away from you; steam scalds faster than boiling water.

4.3 Pressure cooking

What it does: cooks pulses, tough meat, stocks and root vegetables in a third to a quarter of the open-pan time, and it is the most reliable method at altitude.

The science: the sealed pot lets pressure build about 1 bar above the air, which raises the boiling point to about 118–120 °C. Softening of pulse cell walls and conversion of collagen to gelatin run roughly twice as fast for every 10 °C, so 118 °C is about 4–5 times faster than an open pan at 95 °C. Little water is used and little evaporates. (Science of Cooking ch. 8; Wikibooks: Pressure Cooking)

Your equipment: whistle-type cooker. Use the standard you set in Part 1 Test 7: full flame to the first whistle, then lowest flame for X minutes, then natural release. Times below assume this; add 5–10% at altitude and adjust after your benchmark dal.

Timing chart (minutes on low after the first whistle)

Method: pressure-cooked dal (base for 4.7)

1. Rinse dal until the water is nearly clear; add water, ¼ tsp turmeric and a few drops of oil (cuts foaming).
2. Fill no more than half full. Full flame to the first whistle, then lowest flame for the chart time.
3. Natural release (10–15 min) so foam doesn't spurt through the vent.
4. Whisk smooth, adjust thickness with hot water, salt, then add a tarka (Part 5.3).

Nutrient note: short time, little water and a closed pot give good retention of B vitamins and minerals, which stay in the dal liquid. Full pressure cooking destroys pulse lectins completely and lowers phytates further after soaking. Soaking water from rajma and chickpeas is discarded.

Cuisine examples: IN — dal, rajma, chole, mutton curry, khichdi; PL — bigos base or rosół stock in a fraction of the time; IT — risotto in 6–7 min, ossobuco 30 min; FR — stocks (Koffmann's chicken stock), pot-au-feu.

Common faults

Safety: check the gasket and vent before each use; never force the lid; never pressure-cook with less than 250 ml liquid; keep fill at two-thirds maximum (half for pulses and grains).

4.4 Braising and stewing

What it does: browns food in fat for flavour, then cooks it slowly, partly (braise) or fully (stew) covered in liquid, until tough cuts turn tender and the liquid becomes a sauce.

The science: muscle proteins tighten and squeeze out juice above about 60 °C, but the collagen in shoulder, shin, neck and thigh only melts into gelatin with long, moist heat at 70–95 °C. Gelatin coats the fibres so the meat feels juicy even though it has lost water. A gentle simmer, not a boil, keeps the fibres from tightening further. Browning first adds Maillard flavour the liquid alone can't create. (Science of Cooking ch. 8; Lab Manual ch. 11)

Your equipment: heavy triply casserole or kadai on the hob; the OTG at 150–180 °C for oven braises (gentler, even heat from all sides; check the casserole fits with the lid on); pressure cooker to cut braising time to about a third (4.3).

Method (any braise)

1. Dry and season the meat; dust with flour if you want a thicker sauce (Koffmann: flour helps the crust and thickens the gravy).
2. Sear in batches in a generous film of hot oil, without crowding, until golden. Set aside.
3. Aromatics: in the same fat, soften onion, carrot, celery (French/Polish) or build a masala (Part 5.2, Indian).
4. Deglaze with wine, stock, tomato or water, scraping up the browned bits (fond).
5. Return the meat and juices; liquid should come about halfway (braise) or just cover (stew).
6. Cook gently: lid on, barely simmering on the sim burner or in a 150–160 °C oven, until a fork slides in easily.
7. Finish: skim the fat, reduce the liquid if thin, add delicate garnishes last.

Times by cut

Nutrient note: B vitamins and minerals released from the meat stay in the sauce, so serve it. Skim surface fat after chilling for a leaner dish. Long-braised vegetables lose most vitamin C, so add a fresh vegetable or salad on the side.

Cuisine examples

• FR — coq au vin (Koffmann): floured, seared chicken; carrot and onion sweated in butter; red wine and veal stock; 15–20 min in a 180 °C oven; finished with lardons, mushrooms and butter-glazed pearl onions.
• PL — bigos: sauerkraut and fresh cabbage braised for hours with smoked sausage, pork and mushrooms; tastes better reheated over two or three days.
• IN — rogan josh, palak gosht, kheema (Jaffrey): masala sequence (Source notes) then 50–90 min gentle simmer.
• IT — ossobuco alla milanese: floured veal shanks seared, braised in white wine, stock and tomato, finished with gremolata.

Common faults

4.5 Dum and covered oven cooking

What it does: finishes partly cooked meat, rice or vegetables in a sealed pot so they cook in their own steam, absorb each other's flavours and stay moist.

The science: a sealed pot traps steam, so the inside sits near boiling point with almost no evaporation, while the oven heats the pot evenly from every side. That means no scorching at the base and no drying at the top, which a hob can't guarantee. Jaffrey: dum is today's slow-oven baking, replacing the dough-sealed pot set on embers with coals on the lid (IC pp. 68–69).

Your equipment: a heavy lidded casserole that fits the 36 L OTG on the lowest or middle shelf; foil crimped under the lid (or Jaffrey's flour-and-water dough rope); fan off for rice so the top doesn't dry; the true temperature from your Test 3 offset.

Method: pakki (cooked-meat) dum biryani

1. Cook the meat in its masala until just tender and the sauce is thick and clinging (Source notes: chicken \~15 min, lamb \~60 min).
2. Wash basmati until clear; soak 3 h in salted water.
3. Boil hard in plenty of salted water with whole spices until about two-thirds done: 6 min for lamb biryani, 7–8 min for chicken (add \~1 min at altitude). A grain should snap in half with a white core.
4. Layer rice over the meat in a mound; poke a central well to the bottom; streak saffron milk, dot butter, scatter fried onions.
5. Seal: damp cloth on the rice (optional), foil, lid.
6. Oven: 190 °C for 35 min (chicken) or 150 °C for 60 min (lamb).
7. Rest 5–10 min sealed; fold gently from the side with a slotted spoon.

Other dum and covered-oven uses

Nutrient note: sealed cooking loses almost no water, so leached vitamins and minerals stay in the dish. Rice parboiled in excess water loses some B vitamins to the drained water; the long salted soak and short boil keep that loss small.

Common faults

Safety: biryani holds warm for about an hour; refrigerate leftovers within 1 hour and reheat to steaming (rice, Part 1.3).

4.6 Rice and grains

What it does: turns hard grains tender by letting starch absorb water and swell; the method decides whether the grains end up separate (pullao, biryani), clinging (Japanese rice) or creamy (risotto).

The science: starch granules absorb water and burst (gelatinise) between about 60 and 80 °C. Washing removes loose surface starch that glues grains together; soaking pre-hydrates the grain so it cooks evenly and stays long. Frying grains in fat first coats them and keeps them separate. Risotto does the opposite: stirring rubs starch off into the liquid to make the sauce. Cooked starch that cools re-crystallises (retrogradation), forming resistant starch that digests more slowly. (Chemistry of Cooking ch. 18; Science of Cooking ch. 10)

Your equipment: heavy triply pot with a tight lid (foil under it if loose); sim burner; OTG for pullao finishing; pressure cooker for brown rice and khichdi; large pot and large burner for the pasta method.

Five methods compared

Method: pasta al dente

1. 1 L water per 100 g pasta; bring to a rolling boil; 10 g salt per litre.
2. Add pasta, stir for the first minute so it doesn't stick.
3. Start tasting 2 min before the packet time (add 1–2 min at altitude). Al dente: a thin white dot at the centre.
4. Save a cup of cooking water; drain; finish 1 min in the sauce with a splash of that water to emulsify.

Nutrient note: the absorption method keeps all the B vitamins and minerals in the pot; the pasta method drains some away. Brown rice and whole grains keep their bran (fibre, magnesium, B vitamins) but need 12–15 min in the pressure cooker. Cooling cooked rice or pasta overnight raises resistant starch; refrigerate within an hour and reheat to steaming hot (Part 1.3).

Cuisine examples: IN — jeera rice, matar pullao, khichdi, biryani; IT — risotto ai funghi (MPW), arancini from leftover risotto, polenta (cornmeal 1:4–5 water, 40 min stirring or 20 min pressure); PL — kasza gryczana (buckwheat, 1:2 water, 15 min); breakfast — poha, upma (Part 9).

Common faults

4.7 Pulses and dal tadka

What it does: turns dried legumes into soft, digestible, protein-rich dishes; the tadka poured on at the end adds the aroma.

The science: pulse seed coats and cell walls are held together by pectin and hemicellulose that soften only with long, wet heat. Soaking cuts cooking time and leaches out some of the oligosaccharides that cause wind. Hard water (calcium, magnesium) and early acid or salt firm the skins; a pinch of baking soda softens them but destroys some thiamine. Raw kidney beans contain the lectin phytohaemagglutinin, destroyed only by vigorous boiling or pressure cooking. Dal with a grain and yogurt gives complementary protein (Jaffrey, IC ch. 6). (Science of Cooking ch. 7; Lab Manual ch. 5)

Your equipment: pressure cooker (4.3) for every pulse; small triply pan or tadka ladle on the medium burner for the tadka; whisk or wooden madani to smooth the dal.

Soaking guide

Method: everyday dal tadka (serves 4)

1. Rinse 200 g toor dal (or 100 g toor + 100 g masoor); pressure-cook with 600 ml water and ¼ tsp turmeric (4.3: 8–10 min on low, natural release).
2. Whisk smooth; add hot water to the consistency Jaffrey describes: thicker than pea soup, thinner than porridge. Salt; simmer 5 min; lemon juice off the heat.
3. Tadka: heat 2 tbsp ghee or oil until shimmering (about 170–180 °C). Add a pinch of asafoetida (sizzles and swells in 2–3 s), then 1 tsp cumin seeds (darken in 5–10 s), then optional 2 dried red chillies and sliced garlic until golden.
4. Off the heat, add ½ tsp chilli powder for colour (it burns in seconds if the pan is still on the flame).
5. Pour straight onto the dal; it should hiss. Cover 1 min to trap the aroma. Coriander leaves to finish.

Other tadka sets: South Indian — mustard seeds (wait until they pop), urad dal, curry leaves, dried chilli; Gujarati — mustard, cumin, cloves, cinnamon, curry leaves; Bengali — panch phoron; Sodha's golden garlic tarka for chana dal — lots of sliced garlic fried slowly to gold.

Nutrient note: soaking and pressure cooking together lower phytates and lectins and improve iron and zinc absorption; vitamin C from lemon, tomato or a side salad further boosts iron uptake. Keep the cooking water in the dal. Adding the vegetables to the dal (Jaffrey's green lentil curry) keeps their leached vitamins in the bowl.

Cuisine examples: IN — dal tadka, moong dal (Jaffrey), daily masoor dal (Sodha), dal makhani (Sodha: 6 h soak, about 2½ h simmer), chole, rajma; IT — pasta e fagioli, lenticchie; PL — grochowka (split pea soup); FR — lentilles du Puy salad.

Common faults

Dry heat (hot metal, hot fat, hot air, flame) can take a food surface well above 100 °C once its moisture has gone, and that is where browning flavour comes from: the Maillard reaction between amino acids and sugars speeds up sharply above about 140 °C, and sugars caramelise above about 160 °C. The skill is getting the surface dry and hot while the inside cooks just enough. Above about 180–200 °C, browning turns to charring and acrylamide formation in starchy foods rises, so aim for golden, not dark brown. (Science of Cooking ch. 6)

5.1 Searing and pan sauces

What it does: builds a deep brown crust on meat, fish, paneer or mushrooms, then turns the browned residue in the pan (the fond) into a sauce.

The science: a wet surface can't rise above 100 °C until the water evaporates, so drying and a properly hot pan come first. Crust forms by Maillard browning at about 140–180 °C. "Searing seals in juices" is a myth: seared meat loses as much moisture as unseared; searing is for flavour. Protein sticks to steel until the crust forms and releases it naturally. Resting lets carry-over heat even out the centre (Part 1.2). (Science of Cooking ch. 6, 8)

Your equipment: triply frying pan, preheated to the skating-drop stage you found in Test 5, then a thin film of high-smoke-point oil (5.3 table). Probe thermometer. Not non-stick: it browns less and shouldn't be heated empty.

Method: seared steak, chicken thigh or paneer

1. Pat dry; salt at least 40 min ahead (or right before cooking, not in between, when the surface is wet with drawn-out juice).
2. Preheat the pan to the skating-drop stage; add 1 tbsp oil; it should shimmer.
3. Lay the food away from you; don't move it until it releases by itself (steak 2–3 min a side; chicken thigh skin-side 6–8 min on medium; paneer 1 min a side).
4. Cook to target core temperature (Part 1.2); rest on a warm plate.

Method: pan sauce (Koffmann's Bordelaise principle)

1. Pour off excess fat; on medium, sweat finely chopped shallot in a knob of butter until translucent.
2. Deglaze: add wine (or stock, or water) and scrape up the fond. Koffmann reduces half the red wine to a glaze, then the rest by at least half until syrupy.
3. Add stock; bring to the boil; taste and season.
4. Monter au beurre: off the heat, swirl in cold butter for gloss and body. Add the resting juices from the meat at the end.

Nutrient note: high-heat browning of meat forms heterocyclic amines, especially in charred or well-done meat. Keep crusts golden-brown, not black; marinating (especially with herbs, spices and acid) and turning frequently reduce them. Pan sauces with a little butter are fine; most of the fat stays behind if you pour it off first.

Cuisine examples: FR — fillet steak Bordelaise (Koffmann), steak au poivre; IT — scaloppine al limone, saltimbocca; IN — seared paneer for paneer tikka, tawa fish; PL — kotlet schabowy (breaded pork cutlet, shallow-fried; see 5.4).

Common faults

5.2 Sauté, stir-fry and bhuna

What it does: cooks small, even pieces quickly in a little fat over high heat, moving them constantly. Bhuna (bhunao) is the Indian form: frying a masala or meat in fat, stirring and scraping, until the water is gone and it browns, often with splashes of water to stop it catching.

The science: small pieces give a large surface for browning and a short path for heat to the centre. Constant movement prevents any surface from burning while keeping the pan hot. In bhuna, each cycle of adding a little water, evaporating it and frying again dissolves the browned layer from the pan and distributes it through the masala, deepening colour and flavour (the same chemistry as deglazing, 5.1). Onions must lose their water before they can brown, which is why Jaffrey says to start on medium-high and lower the heat as they colour (IC p. 22).

Your equipment: triply kadai or sauté pan on the large burner for stir-fries (use your Test 4 power figure: below \~1.5 kW, cook in smaller batches); flat wooden spatula for bhuna scraping; prep everything first (Jaffrey: masalas cook "in one flowing sweep").

Method: bhuna onion masala (base for most North Indian curries)

1. 3 tbsp oil, medium-high. Whole spices 10–20 s until bay darkens or cardamom puffs.
2. 2 large onions, finely sliced or chopped: 3–4 min on medium-high, then medium for 8–12 min, stirring more as they colour, until rich reddish-brown.
3. Ginger–garlic paste 1–2 min until the raw smell goes.
4. Lower heat; ground spices with a splash of water, 1–2 min.
5. Tomatoes (or yogurt a spoon at a time); fry 5–10 min, adding 1–2 tbsp water whenever it sticks, until the masala is thick, glossy and oil beads at the edges (masala chhod raha hai tel: the oil separates). That is the doneness cue.

Method: stir-fried vegetables (sabzi or Western-style)

1. Cut everything to the same size; pat greens dry.
2. Kadai on full flame; 1 tbsp oil; tempering spices or garlic and ginger 10–20 s.
3. Add hard vegetables first (carrot, beans), then soft (peppers, cabbage, greens); toss every 15–20 s.
4. Salt near the end (salt draws out water and makes the pan stew).
5. Off the heat when just tender and still bright: 3–6 min total.

Nutrient note: quick, low-water cooking keeps most vitamin C and folate; a little fat improves absorption of carotenoids and vitamin K from greens. Bhuna takes onions and tomatoes to full flavour, and cooked tomato with oil delivers more lycopene than raw.

Cuisine examples: IN — bhuna gosht, aloo-gobi sukhi sabzi, bhindi masala, cabbage thoran; IT — funghi trifolati (MPW sautés mushrooms separately to keep them firm); FR — pommes sautées; PL — fried onions and mushrooms for pierogi filling.

Common faults

5.3 Tempering in fat (tadka, baghaar, chhaunk)

What it does: flashes whole spices, aromatics or curry leaves in very hot fat so they release and transform their flavour, then uses that fat either as the first step of a dish (sabzi, rice, curry) or poured over as the last (dal, raita, chutney). Dal tadka is covered in 4.7.

The science: most spice aroma compounds (cumin's cuminaldehyde, mustard's isothiocyanates once crushed, chilli's capsaicin, turmeric's curcumin) dissolve in fat, not water. At about 170–190 °C they volatilise and react in seconds: cumin darkens and turns nutty, mustard seeds pop as internal water flashes to steam, curry leaves crisp. A few seconds more and they burn and turn bitter. Jaffrey: hot oil gives the spices a "new, more concentrated character" (IC pp. 20–21).

Your equipment: small triply pan or tadka ladle on the medium burner; everything measured in small bowls beside the stove; a lid or splatter guard for mustard seeds.

Order of addition (cooking times in hot oil)

Method: tempered dry sabzi (e.g. cabbage, beans, potatoes)

1. 1½ tbsp oil on medium-high until shimmering.
2. Mustard seeds, covered until popping slows; then cumin, curry leaves and a green chilli.
3. Add the vegetable at once (this also stops the spices cooking); turmeric and salt; toss 1 min.
4. Lower heat; cover; cook 5–10 min, stirring occasionally, with a sprinkle of water if it sticks, until just tender.
5. Finish with lemon, fresh coconut or coriander.

Choosing the fat (smoke points are approximate and vary with refining)

Nutrient note: a small amount of fat makes the fat-soluble compounds in spices and vegetables (curcumin, carotenoids, vitamin K) more absorbable; black pepper's piperine greatly increases curcumin absorption. Don't let oil smoke heavily or reuse tadka oil: overheated fat forms oxidation products.

Cuisine examples: IN — jeera aloo, cabbage poriyal, raita with roasted cumin, lemon rice; IT — aglio, olio e peperoncino is an Italian tadka; FR — beurre noisette poured over fish; PL — okrasa: fried onion or bacon and its fat poured over pierogi.

Common faults

5.4 Shallow, deep and oven frying

What it does: surrounds food with fat at 160–190 °C so the surface dehydrates into a crisp, browned crust while the inside steams in its own moisture.

The science: the moment food enters hot oil, its surface water boils violently outward; that outward flow of steam is what keeps oil from soaking in. Oil absorption happens mostly when food is too cool (oil below \~160 °C) or as it cools after frying, so drain at once. Batters work by drying into a lacy shell: cold water and rice flour or besan limit gluten so the coat stays crisp, and a pinch of baking soda adds bubbles. Overcrowding drops oil temperature by 20–40 °C. (Lab Manual 6.2; Science of Cooking ch. 6)

Your equipment: triply kadai for deep-frying (Jaffrey: the karhai needs the least oil for depth; about 5 cm oil); clip-on or probe thermometer; spider or slotted spoon; tray lined with paper or a rack. OTG at 220 °C fan for oven-frying.

Oil temperatures

Method: deep-frying

1. Heat 5 cm oil in the kadai on medium; check with the thermometer (no thermometer: a cube of bread browns in \~60 s at 175 °C).
2. Fry in small batches; let the oil recover to temperature between batches.
3. Drain on a rack or paper; salt immediately.
4. Cool, strain and store the oil (Part 1.3 reuse limits; Jaffrey: top up half old, half fresh; keep fish oil for fish).

Method: oven "frying" in the OTG

1. Cut potatoes, okra, cauliflower or paneer into even pieces; dry very well.
2. Toss with 1 tbsp oil per 500 g plus spices (Sodha's baked masala chips).
3. Single layer on a preheated tray, 220 °C fan, top-middle shelf; 25–35 min, turning once. Uses about one-tenth the oil of deep-frying.

Shallow frying: oil 3–5 mm deep, for cutlets, tikkis, kotlet schabowy, paneer, eggs; medium heat; turn once.

Nutrient note: deep-fried foods absorb about 5–20% of their weight in oil; keep temperatures right and drain well to stay at the low end. Starchy foods form acrylamide when fried or roasted dark: aim for golden, not brown; soaking cut potatoes in water first (MPW washes his) lowers it. Repeatedly heated oil degrades, so don't overuse it.

Cuisine examples: IN — pakoras, pooris, samosas, kachori; IT — fritto misto, arancini (MPW); FR — pommes frites; PL — pączki (doughnuts), placki ziemniaczane (potato pancakes, shallow-fried).

Common faults

Safety: never leave hot oil; dry food well (water spits); keep a lid or baking tray beside the pan to smother a fire, and never use water on burning oil; switch off the gas.

5.5 Roasting and grilling in the OTG

What it does: cooks food in hot, dry air (roasting) or under intense radiant heat from the top element (grilling/broiling), browning the outside while the inside cooks through.

The science: an oven moves heat to food far more slowly than water or fat, so roasts take longer but brown evenly once the surface dries. A fan strips away the cool, moist layer of air around the food and speeds both cooking and browning (Test 3: fan settings run hotter at the surface). Radiant heat from a glowing element falls off sharply with distance, so shelf height controls grilling intensity. Large roasts need resting: carry-over can add 3–8 °C (Part 1.2). (Lab Manual ch. 10; Science of Cooking ch. 8)

Your equipment: OTG element and shelf guide

Method: roasted vegetables

1. Preheat to 210 °C fan with the tray inside.
2. Cut to even 2–3 cm pieces; dry; toss with 1 tbsp oil per 500 g, salt and spices.
3. Single layer, space between pieces (crowding steams them). Roast 25–40 min, turning once and rotating the tray for your hot spots.
4. Done when edges are browned and a knife slides in easily.

Method: roast chicken (whole or spatchcocked)

1. Dry the skin; salt 1–24 h ahead, uncovered in the fridge, for crisper skin. Marinate under the skin if spicing (Sodha's whole roast masala chicken).
2. 200 °C fan on a rack over a tray; spatchcocked (backbone removed, flattened) roasts in \~45 min, whole \~60–75 min.
3. Pull at 74 °C in the breast and 80–85 °C in the thigh; rest 10–15 min.

Method: reverse sear (thick steak, lamb chops, paneer blocks)

1. Season; place on a rack in a 110–120 °C oven.
2. Remove when the core is 5 °C below target (Part 1.2), usually 30–60 min.
3. Sear 45–60 s a side in a very hot triply pan (5.1). Even colour edge to edge, no grey band, and little resting needed.

Nutrient note: roasting concentrates flavour without leaching; vegetables keep minerals and fibre, though heat-sensitive vitamin C falls with long roasting. Fat drips away from meat on a rack. Roast starchy vegetables golden rather than dark (acrylamide, 5.4).

Cuisine examples: IN — tandoori chicken (Jaffrey, adapted in Source notes), chicken tikka (Sodha), roasted aloo gobi salad (Sodha); FR — whole baked sea bass with preserved lemon and tomato (Koffmann); IT — verdure al forno, porchetta-style pork; PL — roast duck with apples (kaczka z jabłkami).

Common faults

5.6 Open-flame cooking on LPG

What it does: uses the burner's flame directly to puff flatbreads, char vegetable skins for smoky flavour, and toast papad, with no pan and no oil.

The science: an LPG flame is about 1,900 °C at its tip and transfers intense radiant and convective heat. On a phulka, the flame flashes the water in the half-cooked dough into steam, which inflates the bread between its two cooked skins. On aubergine or peppers, the skin chars and the flesh inside steams in its own juice; burning lignin and sugars create smoky compounds (guaiacol and others). Wrapping the hot vegetables afterwards lets trapped steam loosen the skin (MPW).

Your equipment: medium or large burner; tava or heavy triply pan for half-cooking breads; flat tongs; a wire rack (roti jali) set on the burner for aubergines and peppers, or rest them directly on the grate as MPW suggests; foil under the grate to catch drips.

Method: phulka (from chapati dough, Source notes)

1. Roll a 15–16 cm disc with dry flour.
2. Tava on medium-high: first side until small bubbles show (15–20 s); flip; second side until brown spots appear (30–40 s).
3. Lift with tongs and place first side down directly on a medium flame; it puffs within 2–3 s. Turn for 2 s more.
4. Stack in a cloth-lined box; brush with ghee if you like.

Method: charred aubergine (baingan bharta, baba ganoush)

1. Prick a large aubergine a few times (stops it bursting); rub lightly with oil.
2. Directly on a medium-high flame, turning every 2–3 min with tongs, until the skin is blackened all over and the aubergine collapses: 12–18 min.
3. Wrap or cover in a bowl for 15–20 min (MPW) so it steams and the skin slips off.
4. Peel, discard the stem, mash. For bharta, cook into a bhuna of onion, tomato, garlic and green chilli (5.2); for baba ganoush, mix with tahini, garlic, lemon and olive oil.

Method: papad (Jaffrey's flame method; Sodha's dry pan)

With tongs, wave over a medium flame 10–20 s, turning, until it blisters and changes colour all over. Or dry-toast in a very hot pan 15 s a side, pressing with tongs (Sodha). Far less oil than frying.

Nutrient note: no oil is needed. Keep charring to the skin you discard. Blackened food contains polycyclic aromatic hydrocarbons, so peel aubergines and peppers well and don't char breads.

Cuisine examples: IN — phulka, baingan bharta, roasted corn (bhutta), smoky tomato chutney; Middle East via MPW — baba ganoush; IT — peperoni arrostiti (charred peppers in olive oil); PL — not traditional.

Common faults

Safety: keep sleeves and tea towels clear; turn off the gas at the knob when you finish; clean the burner ports afterwards (blocked ports make yellow, sooty flames).

5.7 Confit and low-temperature cooking

What it does: cooks food slowly in fat (confit) or dry air well below boiling point, so tough cuts become meltingly tender and delicate fish stays silky, with no overcooked outer layer.

The science: fat at 90–95 °C doesn't boil, so it surrounds the food at a precise, steady temperature; collagen in duck legs slowly turns to gelatin over hours while the muscle stays moist. For fish, fat held at 45–50 °C sets the proteins only just enough. The salt cure first draws out surface moisture and seasons deeply. Cooling in the fat stops evaporation, so the meat stays juicier (Koffmann). (Chemistry of Cooking ch. 22, low-temperature cooking)

Your equipment: a small, heavy triply saucepan on the small burner at its lowest (Test 4 sim) with the probe clipped in, to hold the fat at the target ±3 °C by nudging the flame; a cartouche (circle of baking paper) on the surface. Many manual OTG dials don't go below \~100 °C or are imprecise there, so use the hob for confit and the OTG for low roasting at 110–150 °C.

Method: duck (or chicken) leg confit (Koffmann)

1. Cover legs with coarse salt; refrigerate 12–24 h. Brush off and rinse.
2. Heat enough duck fat (or ghee/oil) to cover to 90–95 °C: calm, the slightest bubble.
3. Slide the legs in (barely any reaction); cartouche on top; hold at 90–95 °C about 2½ h (chicken thighs: about 1½ h) until a skewer slides out of the thickest part easily.
4. Cool in the fat to room temperature, then lift out. Crisp skin-side down in a dry pan, or in a hot oven if chilled.

Method: confit salmon (Koffmann)

Hold fat at 45–50 °C; slide in a 190 g centre-cut fillet; cook gently (about 15–20 min) until a skewer passes through easily. Translucent and silky.

Low and slow in the OTG

Nutrient note: confit is high in fat, but most of the fat stays in the pot: lift the meat out and drain. The fat can be strained and reused for roasting potatoes. Low-temperature methods retain more moisture and form far fewer browning by-products than high heat.

Cuisine examples: FR — duck confit with braised red cabbage, salmon confit with peas, lettuce and ham (Koffmann); IT — pomodori confit, tuna sott'olio; IN — slow dum cooking (Part 4.5) is the closest relative; PL — no traditional equivalent, though roast duck with red cabbage pairs the same way.

Common faults

Safety: garlic or herbs stored in oil at room temperature risk botulism, so refrigerate garlic confit and use it within 4 days, or freeze. Salmon at 45–50 °C is not pasteurised: use very fresh fish, and avoid it for pregnant, elderly or immunocompromised diners.

Richard Bertinet: "Good dough makes good bread. It is as simple as that." This part follows his course for bread, the Iowa State lab manual and Chemistry of Cooking for the science of flour, leavening, cakes and pastry, Koffmann for quiche, and Jaffrey and Sodha for Indian breads. Bertinet's temperatures are for a fan oven; use your Test 3 offset.

6.1 Flour, water, yeast, salt

Bertinet's foundation dough uses only these four: 1 kg strong white bread flour, 700 g water, 20 g fresh yeast, 20 g fine salt. Bakers write recipes as percentages of flour weight (baker's percentages), so this is 100% flour, 70% water (hydration), 2% yeast, 2% salt. Scale any amount by keeping the percentages.

The science of fermentation: yeast breaks down sugars (from flour starch broken by the flour's own enzymes) into carbon dioxide and alcohol. Gluten traps the gas; in the oven the gas expands, alcohol and water vapour add lift (oven spring), and the structure sets as starch gelatinises and gluten coagulates (Chemistry of Cooking ch. 47–50). Temperature controls speed: Bertinet's ideal resting spot is 22–24 °C, and dough fermenting in a cool kitchen just takes longer. The fridge slows it overnight for more flavour.

At altitude: dough rises faster in lower air pressure. Use 15–25% less yeast or watch it closely; Bertinet's rule already fits: prove until "just under" double, never over (Part 1.4).

6.2 Making dough: by hand, then the stand mixer

What it does: turns a sticky mass into a smooth, elastic dough full of air. Bertinet's view: learn it by hand first so you know the feel you're asking the machine to reach; machines were invented to mimic hands.

The science: stretching and folding aligns gluten proteins into sheets (2.4) and traps air pockets that become the bubbles yeast later inflates. Bertinet doesn't "knead" or "knock back" in the sense of pushing air out; he stretches and folds to bring air in, and avoids adding flour, which would dry the dough.

Method: Bertinet's hand technique (summarised; watch his video lessons for the movement)

1. Mix flour, crumbled yeast, salt and neutral-temperature water in a bowl with a scraper until it looks like sticky porridge.
2. Turn out onto an unfloured surface. Resist adding flour.
3. Stretch and arc: slide your fingers under the dough, lift it, slap it down "tail first", stretch it up and outwards, then fold it forward over itself, trapping air. Repeat with rhythm.
4. Skim: when it gets too sticky to control, slide the scraper under it to gather it, then carry on stretching and arcing.
5. Finish when the dough is smooth, silky, elastic and pulls cleanly off the surface (typically 5–10 min); shape it into a ball with a few quarter turns.
6. Rest covered with a cloth in a cosy, draught-free spot (22–24 °C) for about 1–1½ h, until just under double.

Method: stand mixer

1. Use cool water (Bertinet), or work out the exact water temperature from your Test 8 friction factor so the dough finishes at 24–26 °C.
2. Water in the bowl first, then flour, yeast and (a minute later) salt.
3. Dough hook: speed 1 for 2 min to combine, then speed 2 for 5–8 min until the dough comes away cleanly from the bowl and passes the windowpane test.
4. Optionally finish with a minute of stretch-and-fold by hand.
5. Paddle, not hook, for very wet or rye doughs (Bertinet's rye). Don't run above medium speed for long: the motor and the dough both overheat.

Proving cues (Bertinet): check every 30 min. Ready when the dough is domed, firm and springs back slowly when pressed lightly with a fingertip. Under-proving is better than over-proving, which makes the dough wrinkle and collapse. Cover with a cloth plus a large bag to stop a skin forming in draughts.

Common faults

6.3 Lean breads in a 36 L OTG

What it does: bakes crusty, open-crumbed bread from lean dough (flour, water, yeast, salt) in a small home oven.

The science: a very hot start gives oven spring: gas and steam expand fast before the crust sets. Steam in the first minutes keeps the surface soft so the loaf can expand, then gelatinises surface starch into a thin, shiny, crackly crust. A preheated stone or heavy tray delivers a burst of heat to the base (Bertinet: the initial surge "seals the base of the bread"). Big loaves need the heat turned down after 10 minutes or the crust burns before the centre is baked.

Your equipment and its limits: a 36 L OTG holds one tin loaf, two 30 cm baguettes or one 28 cm pizza at a time; the dial may top out at 230–250 °C. Use an upturned heavy baking tray or a baking stone/steel that fits the rack; preheat it with the oven for at least 30–45 min (Bertinet preheats stones for an hour). Lower-middle shelf for loaves (the top element is close), top-middle for pizza.

Steam in an OTG: Bertinet mists inside the oven with a spray bottle as the bread goes in. In a small OTG, aim the spray at the oven floor and walls, never at the glass door, the bulb or the elements. Alternative: a small metal tray on the oven floor, preheated, into which you pour 100 ml boiling water as the loaf goes in. Skip steam for egg-glazed bread.

Bake guide (Bertinet's temperatures, fan)

Oven temperatures, the tin-loaf and focaccia timings are Bertinet's; the baguette time is Bertinet's; the ciabatta time is a typical value to check against his lesson notes and your oven. Pizza is covered in full in Part 10.5.

Scoring: a quick, confident slash 5–10 mm deep with a razor or very sharp knife just before baking controls where the loaf opens (Bertinet: cut cleanly, don't drag).

Nutrient note: long, slow fermentation (overnight in the fridge, or a ferment) breaks down some phytate and partially breaks down gluten and FODMAPs, which some people find easier to digest. Replace 20–30% of the white flour with wholewheat or rye for more fibre without losing the texture.

Common faults

6.4 Rye and sourdough

What it does: makes deeper-flavoured, longer-keeping breads using rye flour or a home-grown culture of wild yeasts and lactic bacteria instead of (or alongside) commercial yeast.

The science: rye has little gluten (Bertinet: 100% rye is very dense), so its structure comes from pentosans (gums) that hold water; its dough is "more like a thick batter". Rye is rich in amylase enzymes that would break its starch into a gummy crumb; the acidity of a sourdough or long ferment slows them. A sourdough starter is a stable community of wild yeasts (for gas) and lactic acid bacteria (for sourness and keeping quality); the acid also lowers phytate and slows staling (Chemistry of Cooking ch. 31).

Your equipment: stand mixer with the paddle for rye; mini loaf tins (Bertinet uses 9 × 6 × 4 cm) suit a small OTG well; a clear jar for the starter; the fridge for slow fermentation; a proving basket or a bowl lined with a floured cloth.

Method: Bertinet's rye bread (summarised)

1. Poolish: 250 g dark rye flour, 6 g fresh yeast, 275 g warm water mixed to a thick paste; cover and leave 3–12 h (overnight is best) until spongy with air pockets.
2. Dough: add 250 g water, 200 g dark rye, 210 g strong white flour, 20 g fresh yeast, 15 g salt, 1 tbsp ground coffee ("almost like a spice"), 1 tsp caraway, optional 250 g sultanas. Mix with a wooden spoon or the mixer's paddle; it stays sticky.
3. Fill ten small tins (\~140 g each) or one large tin; prove until risen; bake (small loaves bake quickly; extend for one big loaf).

Method: sourdough starter (Bertinet's four stages, summarised)

Then keep feeding it regularly (Bertinet's lesson 20), and freeze or dry a portion as a back-up (lesson 21). In the mixer, mix the sourdough 5–6 min, add the salt, then 5–6 min more until it comes away cleanly from the bowl.

Cool-kitchen note: at 15–20 °C a starter and sourdough take 1½–2 times as long. Use the OTG proving trick (Part 9.3: probe to 26–30 °C) or a spot near the stove.

Nutrient note: wholegrain rye and sourdough have more fibre and a lower blood-sugar response than white yeasted bread; long fermentation improves mineral availability.

Common faults

6.5 Enriched doughs: brioche and buns

What it does: adds butter, eggs, sugar or milk to dough for a soft, rich, tender crumb: brioche, buns, babka, challah-style loaves, stollen, pav.

The science: fat coats gluten strands and shortens them, so the crumb is tender instead of chewy; sugar holds water and feeds yeast but in large amounts slows it; eggs add protein (structure), colour and emulsifiers. Enriched doughs ferment more slowly and brown faster (more sugar and protein for Maillard reactions), so they bake at lower temperatures. Butter melts at about 32–35 °C: if the dough gets warm, the butter seeps out and the dough turns greasy and heavy (Bertinet).

Your equipment: stand mixer with dough hook (Bertinet recommends a mixer for brioche because it's so sticky and mustn't be overworked); cold butter softened by bashing it between two sheets of greaseproof paper with a rolling pin; the fridge for resting.

Method: brioche (Bertinet's approach, summarised)

1. Bertinet's brioche has no milk, and butter is almost half the flour weight: a very rich dough.
2. Mix flour, yeast, sugar, salt and eggs with the hook on slow speed until combined.
3. Turn up to medium and add the cold-but-pliable butter a piece at a time so it is absorbed without warming the dough.
4. Rest and prove in a cooler place than usual, so the butter stays in the dough; overnight in the fridge makes shaping much easier.
5. Shape (100 g balls for buns, à tête in a fluted tin, or balls packed into a loaf tin) keeping the smooth top uppermost.
6. Prove 45 min–1 h until just under double.
7. Glaze: beat egg with a pinch of salt about 1 hour ahead (the salt deepens the colour); brush two thin coats ("caress the dough").
8. Bake at 180 °C (lower than lean bread, to stop burning), buns 15–18 min until shiny and golden. No steam with an egg glaze.

Nutrient note: enriched breads are treats: richer in fat and sugar and lower in fibre. Babka and stollen with nuts and dried fruit add some fibre; a part-wholemeal flour or fruit filling helps.

Cuisine examples: FR — brioche, pain au lait; PL — chałka (braided egg bread), drożdżówki (sweet yeast buns), pączki (5.4); IN — pav for pav bhaji (Sodha's "Disha's pav bhaji"), Goan poi with toddy ferment; IT — panettone.

Common faults

6.6 Pastry, quiche and cakes

What it does: uses fat, flour, eggs, sugar and chemical or egg-foam leavening to make tender, flaky or light baked goods.

The science: these are low-gluten products (2.4). In pastry, cold fat coats flour so little gluten forms; flakes of fat melt and release steam in the oven, separating layers. In cakes, creaming butter with sugar beats in air bubbles that baking powder then enlarges; eggs set the structure. In muffins and quick breads, wet and dry are mixed only until combined, because overmixing develops gluten and makes tunnels. Egg-white foams (soufflés, angel cake) trap air in stretched egg proteins that set in the oven (Lab Manual ch. 9, 12, 13; Chemistry of Cooking ch. 36, 54–55).

Your equipment: stand mixer with the paddle (creaming) and whisk (egg whites, cream); OTG on the lower-middle shelf, fan off or reduced 10–20 °C for cakes (Appendix B); tart tin with removable base; baking beans or raw rice for blind baking; scale.

Mixing methods compared (Lab Manual)

Method: quiche Lorraine (Koffmann, summarised)

1. Pastry: 500 g plain flour in a well with a pinch of salt; 4 eggs, 100 ml cold water and 400 g softened butter in the middle; mash together, then bring in the flour by hand until absorbed. Wrap and chill completely.
2. Oven 160 °C. Roll 1–2 mm thick; line the tin with an overhang; trim by rolling the pin across the top; prick the base.
3. Blind bake: line with greaseproof paper and fill with uncooked rice or lentils; bake about 20 min until firm and lightly golden; remove the paper and rice.
4. Filling: 225 g lardons (fried), 150 g grated Gruyère, then 3 eggs + 3 yolks whisked with 375 ml milk, 375 ml cream, salt, pepper and nutmeg.
5. Bake until just set at the edge with a wobble in the centre; Koffmann takes it out "before it is fully set" so carry-over finishes it.

Nutrient note: pastry and cakes are energy-dense treats; Koffmann's quiche pastry is 80% butter by flour weight. For everyday baking, swap a third of the flour for wholemeal, cut sugar by up to 25% in most cake recipes without failure, and use fruit and nuts for sweetness and fibre.

Common faults (Lab Manual defect tables, condensed)

6.7 Indian breads: chapati, paratha, naan

What it does: makes everyday unleavened flatbreads on the tava and flame, and yeasted naan in a pan or the OTG.

The science: atta's finely milled bran and damaged starch absorb a lot of water, making a soft dough with moderate gluten that stays pliable when rested. A very hot surface cooks the outside quickly while steam inside puffs the bread (Jaffrey: preheating the tava stops the chapati going hard and brittle). In paratha, layers of ghee separate sheets of dough so they puff into flaky layers. Naan gets its softness from yogurt, milk and a little fat, and its lift from yeast plus baking powder.

Your equipment: heavy tava or triply/cast-iron frying pan; LPG flame for puffing (5.6); rolling pin and board; OTG at maximum with a preheated stone or upturned tray for naan.

Method: chapati and phulka — see Source notes (Jaffrey and Sodha compared) and Part 5.6. In short: 450 g atta, ½ tsp salt, 3 tbsp oil rubbed in, \~300 ml hot water, knead 6–8 min to soft and pliable, rest 20–30 min; roll 16 cm; tava medium-high 30–40 s a side, then puff on the flame or press on the tava.

Method: layered paratha

1. Chapati dough (above), rested.
2. Roll a 15 cm disc; spread ½ tsp ghee and dust with atta.
3. Fold in half, ghee and dust again, fold into a triangle (or roll up into a rope and coil it for a round, more layered paratha); roll out gently to 3–4 mm.
4. Tava on medium: cook 30 s, flip; brush with ghee; flip and press with a spatula until golden spots cover both sides, about 2–3 min in all.
5. Stuffed (aloo, gobi, paneer, Sodha's cinnamon-lamb): seal the filling in a ball of dough, roll gently, cook a little longer on lower heat.

Method: naan (Sodha's "Aunty Harsha's naan", summarised)

1. 500 g plain flour; in a well add 2 tbsp oil, 4 tbsp whole-milk yogurt, 7 g dried yeast, 2 tsp sugar, 2 tsp salt, 1 tsp baking powder; rub to crumbs.
2. Add about 275 ml hand-hot milk gradually to a very sticky, soft dough; knead about 5 min on a floured surface; oil lightly.
3. Rise in a warm place at least 1 h, until doubled.
4. Divide into 12; roll each to about 12 × 20 cm.
5. Pan (Sodha): dry pan on medium-high; cook until bubbles appear (20–30 s), flip, the same on the other side.
6. OTG option (blistered, tandoor-like): stone or tray preheated at maximum (240–250 °C) with top and bottom elements; 2–4 min until puffed with charred spots; or cook in the pan, then 30–60 s close under the top element.
7. Brush with ghee or garlic butter; stack wrapped in foil or a cloth.

Nutrient note: atta chapatis are wholegrain: much more fibre, magnesium and B vitamins than maida naan. Mixing in besan, millet flour (Sodha's millet flatbread) or methi leaves adds protein, variety and plant count (9.5). Brush ghee lightly, not on every bread.

How eggs and milk set, curdle and culture, and how salt, acid, oil, microbes and cold keep food. Everyday egg cookery is in Part 9.1; the science of protein setting is in Part 2.3.

7.1 Custards and egg foams

What it does: uses egg proteins to thicken milk into custards and sauces, or traps air in whipped whites for soufflés and meringues. Rice puddings (kheer, phirni) thicken with starch instead.

The science: diluted in milk and sugar, egg proteins set at a higher temperature than whole eggs: a stirred custard thickens at about 80–82 °C and curdles above about 85 °C (2.3). Sugar raises the setting point further; starch (a little cornflour) protects against curdling. Whipping egg whites unfolds their proteins, which then re-link around air bubbles; fat (a trace of yolk, a greasy bowl) stops foam forming, while acid (lemon, cream of tartar) and sugar stabilise it. Heat expands the air and sets the protein walls (Lab Manual ch. 8–9).

Your equipment: heavy triply saucepan and a wooden spoon or silicone spatula; probe thermometer; stand mixer with the whisk for whites; OTG with a water bath (roasting tin of hot water) for baked custards, at 150–160 °C, fan off.

Method: crème anglaise (stirred custard)

1. Heat 500 ml milk (or milk and cream) with vanilla or cardamom to steaming.
2. Whisk 5 yolks with 80 g sugar; pour the hot milk on slowly, whisking (tempering).
3. Return to low heat, stirring constantly in a figure of eight, until it coats the back of a spoon and a finger drawn through leaves a clean line: about 80–82 °C (the Lab Manual gives 77–84 °C depending on how many eggs per cup of milk; richer custards set lower).
4. Strain at once into a cold bowl. For ice cream or kulfi, chill and churn.

Method: baked custard (caramel custard, crème caramel)

2 eggs + 2 yolks, 60 g sugar, 400 ml warm milk, strained into ramekins over caramel; bake in a water bath at 150–160 °C for 30–45 min until set at the edges with a slight wobble in the centre (Lab Manual 8.2: until a knife inserted comes out clean; then cool quickly).

Method: kheer and phirni

• Kheer: 50 g washed rice in 1 L full-fat milk, simmer gently 45–60 min, stirring often so it doesn't catch, until creamy; sugar, cardamom and nuts at the end (sugar added early slows the rice softening). Pressure cooker: 1 whistle, then 10 min on low.
• Phirni: soaked rice ground to a coarse paste, whisked into hot milk and stirred 10–15 min until thick; set in clay or small bowls (Sodha's fig firni).

Method: soufflé (principle, Koffmann's pistachio soufflé)

A thick flavoured base (pastry cream or flavoured sauce) lightened with whites whipped to stiff, glossy peaks, folded in thirds; buttered and sugared dishes; straight into a preheated oven; serve immediately. Koffmann pairs his with ice cream.

Nutrient note: egg and milk give high-quality protein, calcium and B12; custards are also sugar-rich. Jaggery or dates can replace some sugar in kheer; cardamom, saffron and nuts add flavour without much sugar.

Common faults

7.2 Dairy: dahi, paneer, ghee, khoya

What it does: turns milk into the staples of the Indian kitchen: set yogurt, hung curd, fresh cheese, clarified butter and reduced milk solids.

The science: milk is an emulsion of fat droplets in water carrying casein proteins (in clusters called micelles), whey proteins and lactose. Acid makes casein clump: slowly and evenly from bacteria (dahi), or instantly from lemon juice near boiling (paneer, chhena). Heat unfolds whey proteins; heating milk before culturing gives thicker yogurt. Evaporation concentrates milk into khoya and rabri. Clarifying removes water and milk solids from butter, leaving stable fat (ghee) (Science of Cooking ch. 3, 5; Chemistry of Cooking ch. 58–64).

Your equipment: heavy triply pan (milk scorches on thin bases); probe thermometer; muslin; OTG as an incubator (Part 9.3 trick, checked at 40–45 °C); microwave for quick khoya.

Staples at a glance (full methods in Source notes — Indian cookery)

Microwave khoya shortcut: full-fat milk powder 100 g + 50 ml milk + 1 tbsp ghee in a wide bowl; 1 min bursts at full power, stirring between, 3–5 min total, until it holds together.

Why milk curdles in curries and how to stop it (Part 2.3): acid (tomato, tamarind) plus heat plus salt makes casein clump. Use full-fat yogurt at room temperature, whisk it smooth, add a spoon at a time over moderate heat (Jaffrey), or stabilise it with 1 tsp besan or cornflour per 200 g. Add cream or milk after the acid has cooked down, and don't boil hard afterwards.

Nutrient note: dahi's live cultures count as a fermented food (9.5); its lactose is partly digested, so many people who struggle with milk tolerate it. Paneer keeps most of milk's protein and calcium. Ghee is almost pure fat; use it for flavour in small amounts.

Common faults

7.3 Fermentation

What it does: lets salt-tolerant lactic acid bacteria, already present on vegetables (or in a starter culture), turn sugars into lactic acid, preserving the food and making it sour, complex and alive.

The science: salt (about 2–3% by weight) and the absence of air under brine suppress spoilage microbes while lactic acid bacteria thrive; within days they drop the pH below about 4, at which harmful bacteria can't grow. Temperature sets the pace: 18–24 °C is ideal; cooler is slower and often tastier; warmer is fast and can turn soft. Spector: home ferments can carry up to 30 live microbe varieties against two or three in some shop versions; eat "little and often" (Science of Eating Well, lesson 15). Fermentation also raises some B vitamins and lowers phytate (2.6).

Your equipment: wide-mouth glass jars, washed in hot soapy water and rinsed with boiling water; a weight to keep vegetables under brine (a small water-filled bag or a smaller jar); kitchen scale (salt by weight, not volume); cloth or loose lid so gas escapes.

Five ferments

Idli and dosa batter, dahi and sourdough are fermentations too (9.3, 7.2, 6.4).

Method: sauerkraut

1. Weigh shredded cabbage; add 2% of that weight in non-iodised salt.
2. Massage 5–10 min until liquid pools; pack tightly into a jar, pressing until brine covers the cabbage by 2 cm.
3. Weight it down; loosely cover; stand on a plate (it can overflow).
4. Press down daily for the first week; taste from day 5; refrigerate when you like the sourness.

Nutrient note: live fermented vegetables add microbes and their by-products; cooking kills the microbes (the flavour remains). Fermented vegetables can be salty, so a forkful or two a day is the right amount (Spector: little and often).

Common faults and safety

7.4 Pickling: achaar and quick acid pickles

What it does: preserves vegetables and fruit with salt, acid, oil and spices. Indian oil pickles (achaar) often ferment in the jar; quick pickles use lime juice or vinegar and are ready in an hour.

The science: salt draws water out of the vegetable (osmosis) and, with time, lets lactic bacteria sour it; mustard oil and spices (mustard, fenugreek, turmeric, chilli, asafoetida) add antimicrobial compounds and seal the surface from air. Heating mustard oil until very hot, then cooling it, drives off much of its harsh pungency (Jaffrey: it turns "from a pungent oil to a sweet one"). Vinegar or lime pickles rely on acid: below about pH 4.6 harmful bacteria can't grow (Lab Manual 2.2 osmosis; Chemistry of Cooking ch. 51–53).

Your equipment: glass or ceramic jars with non-metallic lids (acid corrodes metal); dry spoons only (water introduces mould); a sunny windowsill, or the OTG light for warmth on cold days; a spice grinder for coarse mustard.

Method: cauliflower and white radish achaar (Jaffrey, IC, summarised)

1. Cut 225 g cauliflower into slim florets and 225 g white radish (mooli) into 1 cm rounds (turnip works too).
2. Coarsely grind 4 tsp black mustard seeds.
3. Heat 110 ml mustard oil until very, very hot; turn off and let it cool completely (stay with it).
4. Toss the vegetables with the mustard, 2 tsp salt, ½ tsp turmeric and ½–1 tsp cayenne; mix in the cooled oil.
5. Pack into a 1.2 L jar; keep in a warm, sunny spot by day, indoors at night; shake 3–4 times a day.
6. Ready when sour enough: 4–5 days in summer, about 8 in winter. Store in a cool place.

Quick pickles

Nutrient note: pickles are salty: a teaspoon or two per meal. Lacto-fermented achaar and kiszone pickles may carry live microbes; vinegar pickles don't. Pickles with raw garlic, ginger or lime keep some vitamin C and other compounds.

Common faults and safety

Safety: never store garlic, ginger or herbs in oil at room temperature without acid or salt curing (botulism risk); keep quick oil-based pickles in the fridge.

7.5 Freezing, batch cooking and safe reheating

What it does: makes weekday cooking fast by preparing bases and staples ahead, and keeps them safe and good to eat.

The science: at −18 °C microbes stop growing (they aren't killed), and chemical changes slow to a crawl. Slow freezing forms large ice crystals that rupture cells, so food weeps when thawed; small portions, flat bags and a cold freezer freeze faster and keep better texture. Fats slowly oxidise even frozen, so fatty foods keep for shorter times. Air contact causes freezer burn (dry, discoloured patches). Bacteria multiply between 5 and 60 °C (Part 1.3).

Your equipment: freezer at −18 °C or below (check with the probe); flat zip bags, ice-cube trays, labelled tubs; marker for name and date; shallow trays for fast cooling.

What to batch-make and how long it keeps (frozen at −18 °C)

Thawing: overnight in the fridge, in the microwave on defrost then cook at once, or in a sealed bag under cold running water. Never on the counter (Part 1.3). Curries and dals can be reheated straight from frozen in a covered pan with a splash of water.

Reheating: to 75 °C or steaming throughout, once only; stir and stand when microwaving. Add delicate finishes after reheating: fresh coriander, lemon, a new tadka, cream.

A sample Sunday batch session (about 2 hours): a pot of pressure-cooked dal (4.3); 1 kg bhuna onion masala (5.2) frozen in cubes; tomato masala base; ginger–garlic paste; a jar of lime-pickled onions; idli/dosa batter set to ferment; a tray of roasted vegetables (5.5). That covers four to five weekday dinners with 15–20 minutes' cooking each.

Nutrient note: freezing preserves most vitamins well, often better than several days in the fridge; most loss happens in blanching and reheating, so keep both short.

Marco Pierre White: "I am just the architect, while Mother Nature is the true artist." His vegetarian course rebuilds humble vegetables as centrepieces; Indian home cooking has always made vegetables the main event. This part combines both, with Koffmann's mash and Wikibooks' pierogi. Nutrient principles are in Part 2.5; the cooking methods themselves are in Parts 4 and 5.

8.1 Potatoes

What it does: five classic preparations, each depending on choosing the right potato and controlling its starch.

The science: floury (mealy) potatoes have more starch in looser cells that separate when cooked: fluffy mash, crisp chips. Waxy potatoes have less starch and firmer cells that hold their shape: gratins, boulangère, salads. Indian markets rarely label them: older, dry-skinned potatoes with a powdery cut surface behave as floury; new, smooth, moist ones as waxy. Washing cut potatoes removes surface starch (and reduces acrylamide, 2.2) so slices don't glue together and chips crisp; drying them lets them brown. Overworking hot cooked potato ruptures the starch cells and turns mash gluey (Science of Cooking ch. 7).

Your equipment: potato ricer or masher (never a blender for mash); mandoline with hand guard for 2 mm slices and matchsticks; heavy triply sauté pan for rösti; ovenproof dish for gratins; kadai and thermometer for chips.

Five potato dishes

Nutrient note: potatoes supply vitamin C, potassium and fibre, mostly just under the skin: cook them in their skins where you can (boiled, baked, pressure-cooked 5–6 min, 4.3) and peel afterwards. Cooled cooked potatoes form resistant starch (2.4). Cream-and-butter dishes are occasional treats.

Common faults

8.2 Bag-poached and braised vegetables

What it does: cooks whole vegetables gently in their own juices (MPW's sous-vide-style poaching) or in a little flavoured liquid (braising), so they taste intensely of themselves and the juices become the sauce.

The science: sealed in a bag, a vegetable can't leach flavour, minerals or water-soluble vitamins into the cooking water; the juices it does release are trapped and reused (MPW's point, and it agrees with Part 2.5). Holding the water just below boiling (MPW: about 95 °C) softens the pectin in cell walls evenly from edge to centre without the outer layer breaking up. Lemon on cut surfaces stops enzymatic browning. Braising adds aromatics, wine and stock, and reduces them into a glaze (4.4).

Your equipment: heat-safe roasting or vacuum bags (MPW's alternatives: a roasting/poaching bag, or a tight wrap of cling film rated for cooking); a large triply pot on the sim burner with the probe in the water. At \~95.5 °C boiling point (1,370 m), "just below boiling" means about 88–92 °C: barely moving water.

Bag-poaching times (MPW)

Method: artichokes barigoule (braise, MPW after Roger Vergé)

1. Trim artichokes to the heart and stem, remove the choke; hold in lemon water.
2. Sweat sliced carrots, onions, garlic, bay and thyme in olive oil in a casserole.
3. Add the artichokes; pour in white wine and reduce until you can no longer smell its acidity.
4. Add vegetable stock; braise gently until tender; finish with basil butter (basil blended with olive oil and butter).

Indian equivalents: dum vegetables in a sealed pot (4.5) and Jaffrey's covered cauliflower bhaji (8.5) work on the same principle: little water, a lid, gentle heat.

Nutrient note: bag-poaching and covered braising keep far more of the water-soluble vitamins and potassium than boiling and draining (2.5). Use the bag juices; they hold what the vegetable released.

Common faults

8.3 Gratins, stuffed and baked vegetables

What it does: turns vegetables into centrepieces by pre-cooking them to concentrate flavour, filling them, and finishing in the oven under a crust.

The science: most stuffed vegetables hold a lot of water, so MPW pre-cooks each part separately (frying, roasting, microwaving or bag-poaching) to drive off water and develop flavour before assembly; otherwise the dish steams and turns soggy. A crust of breadcrumbs, cheese and herbs browns in dry heat (Maillard, 2.2) while the inside just heats through, which is why his gratins bake at moderate temperatures (140–180 °C).

Your equipment: OTG (middle shelf; top element for the final browning); microwave for quick aubergine "caviar"; kadai for frying components; probe to check a stuffed vegetable is hot through (75 °C).

MPW's stuffed and baked dishes

Indian parallels: bharwan (stuffed) baingan, bhindi and karela use the same logic: pre-cook or salt to remove water, fill with a dry spiced masala (besan, peanut, coconut, amchur), then cook covered on low and uncover to crisp; in your OTG, bake at 180 °C brushed with oil. Baingan bharta is the open-flame route (5.6).

Nutrient note: roasting and microwaving vegetables before stuffing keeps more vitamins than boiling. Cream, cheese and fried components make these rich, so serve with a salad or dal; replace some cheese with breadcrumbs, nuts and herbs for a lighter crust.

Common faults

8.4 Vegetable pasta, rice and dumplings

What it does: builds filling vegetarian mains from a starch (pasta, vegetable "sheets", risotto, dumpling dough) plus a vegetable sauce or filling.

The science: a slow-cooked vegetable ragù develops sweetness and depth as onions, carrots and celery soften and brown and tomatoes reduce (2.2), and it tastes better the next day as flavours blend (MPW). Béchamel is a roux-thickened milk sauce (3.3). In arancini, cold risotto's retrograded starch (2.4) holds the ball together; a thin flour–egg–crumb coat browns quickly in 160 °C oil while the inside heats through. Pierogi dough is a soft, rested egg-and-flour dough: resting relaxes gluten so it rolls thin without shrinking.

Your equipment: heavy triply pot for ragù; saucepan and whisk for béchamel; OTG for lasagne; kadai and thermometer for arancini; rolling pin and a 7–8 cm glass or cutter for pierogi; large pot for boiling dumplings.

Method: MPW's vegetable lasagne (summarised)

1. Ragù (ideally a day ahead): grated onion and garlic in olive oil; diced celery, carrot, celeriac and cauliflower with thyme and bay, cooked down slowly; add a good tomato sauce; simmer until thick.
2. "Pasta": MPW replaces pasta sheets with thin slices of bag-poached celeriac (8.2: 75 min just below boiling). Ordinary lasagne sheets work too.
3. Béchamel: 75 g butter + 50 g flour cooked 2 min; whisk in 500 ml warm milk with a bay leaf and nutmeg; simmer 5–10 min; finish with 50 ml cream.
4. Layer ragù, sheets and béchamel; finish with béchamel and grated hard cheese; bake until bubbling and golden (about 180 °C, 30–40 min); rest 15 min before cutting.

Method: arancini (MPW, from leftover risotto, 4.6)

1. Set up three trays: 150 g flour, 4 beaten eggs, 350 g breadcrumbs (for 500 g risotto).
2. Roll cold risotto into 6 cm balls.
3. Roll in flour and shake off the excess; splash egg over (don't roll it in the egg); into crumbs.
4. Egg splash again, firm the shape between your palms, then the lightest dusting of crumbs. MPW's rule: the crust should be as thin as an eggshell.
5. Deep-fry at 160 °C for 8–9 min; drain on paper.

Method: pierogi (Wikibooks, Pierogi I, metric)

1. Dough: beat 1 tbsp salt, 1–2 eggs and 120 ml cold water; mix into \~440 g plain flour; add up to 240 ml more water until soft and slightly wet; add 1½ tbsp melted butter; knead \~15 min until very smooth.
2. Rest covered in the fridge at least 1 h, ideally 24 h.
3. Roll a third at a time to 3 mm; cut circles with a glass; fill with 1 tsp–1 tbsp filling (potato and twaróg/paneer ruskie; sauerkraut and mushroom; or fruit).
4. Fold into half-moons and pinch closed, pressing out air.
5. Boil in batches of a third in salted water 5–10 min (they float when nearly done); drain, rinse lightly; serve or fry in butter with onions (okrasa, 5.3). Freeze uncooked on paper, not touching, up to 6 weeks.

Indian parallels: momos and modak (steamed, 4.2), samosa and kachori (fried, 5.4), and vegetable biryani or tahiri (rice with vegetables, 4.5–4.6).

Nutrient note: vegetable ragù and fillings with pulses, cheese or paneer make these balanced meals; replacing some pasta with vegetable sheets (MPW) lowers refined starch and raises fibre. Arancini and fried pierogi are richer: serve with salad.

Common faults

8.5 Sabzi methods: sukhi, rasedar, bharta, saag

What it does: four templates cover almost every everyday Indian vegetable dish. Learn the template and any vegetable fits it.

The science: all four start with a tadka or masala in fat (5.2, 5.3) to carry fat-soluble spice flavour, then cook the vegetable in its own moisture (sukhi), in a sauce (rasedar), after charring and mashing (bharta), or wilted and puréed (saag). Cooking covered with only sprinkles of water steams vegetables in their own juices and keeps more water-soluble vitamins than boiling (2.5). Acid (lemon, amchur, tomato) goes in late, because it slows softening and dulls green colour (4.1).

Your equipment: triply kadai or wide sauté pan with a lid; pressure cooker for rasedar potatoes and saag; LPG flame for bharta (5.6).

The four templates

Method: sukhi template, cauliflower (after Jaffrey)

1. 3 tbsp oil, medium. 2½ cm ginger blended to a paste with 4 tbsp water, plus ½ tsp turmeric: fry 2 min.
2. Green chilli and a handful of chopped coriander: 2 min.
3. One cauliflower in slim florets: stir-fry 5 min, sprinkling warm water if it sticks.
4. 1 tsp ground cumin, 2 tsp ground coriander, 1 tsp garam masala, 1 tbsp lemon juice, salt and 3 tbsp warm water; stir 3–4 min.
5. Cover and cook on low until tender with a trace of crispness. Jaffrey gives 35–40 min; with slim florets on your triply pan, check from 12–15 min (shorter keeps more vitamin C, 2.5).

Nutrient note: the sukhi and saag templates are among the most nutrient-preserving ways to cook vegetables: little water, a lid, a little fat for absorption, and acid and herbs added at the end. Pairing a sabzi with dal and a whole-grain roti gives the balanced Indian plate Jaffrey describes (IC, Menus).

Breakfast is where technique meets habit: the same few methods, repeated daily, matter more for health than any single dish. Chatterjee's advice is to start the day with protein and real food rather than sugary cereal, and to add vegetables to every meal including breakfast; Spector's is to eat a wide variety of plants and some fermented food. The pages below give the techniques to do that quickly.

9.1 Eggs

What it does: sets egg proteins to the texture you want, from a runny yolk to a firm, creamy omelette, in minutes.

The science: egg white proteins begin to set at about 62 °C and are firm by 80 °C; the yolk thickens from about 65 °C and is crumbly by 77 °C. Gentle heat gives tender, moist eggs; high heat squeezes water out (rubbery whites, weeping scrambled eggs). A green-grey ring on a hard-boiled yolk is iron sulphide from overcooking. Cooking makes egg protein about 90% digestible versus about half raw, and frees biotin. (Science of Cooking ch. 9; Lab Manual 8.3)

Your equipment: small triply pan with lid for boiling; non-stick 15–20 cm pan for omelettes (Koffmann insists: 15–18 cm non-stick); probe for poaching water; never microwave eggs in their shells (they burst).

Boiled eggs (from the fridge, lowered into boiling water)

Cool at once in cold water for 2 min; this stops cooking and makes peeling easier.

Method: French omelette (Koffmann)

1. Beat 3 eggs with salt and white pepper using a fork; don't overwork.
2. Melt a generous knob of butter in the pan on medium-high until bubbling.
3. Add the eggs; shake the pan and stir like scrambled eggs.
4. At about 70% set, stop and let the base set for a few seconds.
5. Off the heat, fold the sides, then roll it over by tapping the handle; turn out. It should still wobble inside (Koffmann: dish up while it's still wobbly).

Method: masala omelette (Sodha)

Whisk 2 eggs per person with spring onion, green chilli, coriander, a pinch of turmeric and chilli powder, salt. 1 tsp oil per omelette in a 20–22 cm pan on medium; pour, swirl, leave about 1 min until set but still soft on top; fold. With spring onion and coriander, it starts on Chatterjee's two vegetables per meal.

Method: eggs poached in spiced tomato (Sodha's Parsi "Bombay eggs")

Build a bhuna base of cumin, coriander, sliced onion, garlic, ginger and plenty of fresh tomato (5.2) until thick; make wells, crack in eggs, cover and cook on low until the whites set and yolks are still soft, 5–8 min. Serve with yogurt and bread.

Other methods: poached eggs in water at 80–85 °C (fresh eggs hold together), 3–4 min; scrambled eggs on low heat with butter, stirred slowly, off the heat while still glossy; akuri (Parsi spiced scrambled eggs) the same way with onion, tomato and green chilli.

Nutrient note: eggs are complete protein with choline, vitamin D and B12. Gentle cooking keeps the yolk's nutrients and avoids oxidising its cholesterol. Adding tomato, onion and greens to egg dishes covers the vegetables and fibre eggs lack.

Common faults

9.2 Grains: porridge, overnight oats, poha, upma

What it does: turns quick-cooking grains into a warm or cold breakfast in under 15 minutes.

The science: oats contain beta-glucan, a soluble fibre that thickens porridge and slows the rise in blood sugar; the less processed the oat (steel-cut > rolled > instant), the slower. Soaking oats overnight in milk or yogurt softens them without heat, since rolled oats are already steamed during processing. Poha is rice that has been parboiled and flattened, so it only needs rehydrating, not cooking (Sodha: "it cooks in just 5 minutes"). Upma toasts semolina in fat first so the grains stay separate when hot water goes in, the same principle as frying rice for pullao (4.6). (Science of Cooking ch. 10)

Your equipment: small triply saucepan; kadai for poha and upma; microwave for single-serve porridge (Test 6 wattage).

Method: porridge

1. 40 g rolled oats + 250 ml milk or water (or half and half), pinch of salt.
2. Hob: bring to a simmer, stir 4–5 min until creamy. Microwave: in a large bowl (it foams), 2 min at full power, stir, 30–60 s more. Steel-cut oats: 1:4 liquid, 20–25 min, or 5 min in the pressure cooker.
3. Top with fruit, nuts and seeds rather than sugar.

Method: overnight oats

40 g rolled oats, 100 g yogurt, 100 ml milk, 1 tbsp chia or flax, grated apple or berries; stir, cover, refrigerate 6–12 h. Keeps 2 days.

Method: poha (Sodha's pomegranate and fennel poha, method summarised)

1. Rinse 200 g thick poha in a sieve under cold water for a few seconds until just soft; drain and leave 5 min.
2. 2 tbsp oil, medium heat; tadka of mustard seeds (wait for popping) and fennel seeds (5.3); sliced red onion until soft.
3. Turmeric, salt, peas; then the poha; toss gently 2–3 min until hot through.
4. Off the heat: lemon juice, pomegranate seeds, coriander; peanuts or sev if you like.

Method: upma

1. Dry-roast 150 g coarse semolina (rava) in the kadai on medium, stirring, until fragrant and a shade darker (5–6 min); set aside.
2. 2 tbsp oil or ghee; mustard seeds, urad dal, curry leaves, green chilli, ginger (5.3); onion and chopped vegetables (carrot, beans, peas) 3–4 min.
3. Add 450 ml boiling water and salt; stream in the semolina while stirring constantly to stop lumps.
4. Cover on low 2–3 min; lemon and coriander.

Nutrient note: oats and whole grains supply fibre and slow-release energy; poha is often iron-fortified, and the lemon's vitamin C improves iron absorption. Adding peas, vegetables, nuts and seeds turns these into balanced meals; serve with yogurt or eggs for protein.

Cuisine examples: IN — poha, upma, daliya (cracked wheat porridge), ragi porridge; IT — polenta or toast with ricotta; PL — owsianka (oat porridge), kasza manna (semolina in milk); FR — tartine with fruit.

Common faults

9.3 Pulse pancakes and fermented batters

What it does: turns soaked, ground pulses (and rice) into protein-rich pancakes: unfermented and quick (moong or besan chilla) or fermented overnight (dosa, idli, uttapam).

The science: blending soaked dal at length whips air into the batter, and urad dal's proteins and gums hold that air like egg white does. In fermented batter, lactic acid bacteria (mainly Leuconostoc and Lactobacillus) and wild yeasts produce carbon dioxide and acidity: the batter doubles, sours pleasantly and becomes easier to digest. Fermentation also lowers phytate and raises some B vitamins. Bacteria work best at 28–32 °C, so a cool hill kitchen needs a warm spot.

Your equipment: mixer-grinder (wet jar); heavy pan for pancakes (non-stick is easiest; a well-preheated triply pan works if wiped with oil between pancakes); OTG as a proving box: heat at the lowest setting for 5 min, switch off, put the batter in with the door closed (Sodha uses the same trick for yogurt), or leave only the oven light on. Check with the probe that the air is 28–35 °C before the batter goes in; above about 45 °C the bacteria die.

Method: moong dal pancakes with peas (Jaffrey, IC, Gujarati poore; summarised)

1. Soak 190 g moong dal in 1 L water for 5 h; drain.
2. Blend with ginger, garlic, green chilli, 1 tsp salt, ¼ tsp turmeric and 90 ml water until smooth, then 2–3 min more so the batter turns light and airy.
3. Stir in finely chopped onion, coriander and blanched peas. (Batter keeps 24 h in the fridge.)
4. Just before cooking, stir in ¼ tsp baking soda.
5. 1 tsp oil in a 20 cm pan on medium-low; spiral about 55 ml batter out with the back of a spoon to 14–15 cm; drizzle a little oil on top and around; cover 2 min until the base is golden; flip and cook the other side.

Method: dosa and idli batter (makes about 1.2 kg)

1. Soak 300 g idli or parboiled rice and, separately, 100 g whole skinned urad dal with 1 tsp fenugreek seeds, 4–6 h.
2. Grind the urad with ice-cold water, a little at a time, until very light and fluffy (10 min in a mixer, in two batches). Grind the rice smooth for dosa, slightly gritty for idli.
3. Mix by hand (hand microbes help start fermentation, by tradition) with 1½ tsp salt; the jar should be under half full.
4. Ferment 8–14 h at 28–32 °C until doubled, bubbly and pleasantly sour. In cold weather it may need up to 24 h.
5. Idli: steam (Part 4.2). Dosa: thin the batter slightly; heat the pan until a sprinkle of water sizzles away instantly; wipe with oiled onion half; ladle and spiral out thin; drizzle oil; cook one side until crisp and golden, 1–2 min. Refrigerate the rest; use within 3–4 days.

Nutrient note: dal plus rice gives complementary protein; fermentation improves mineral availability and adds B vitamins. Fill dosas with vegetables (potato and onion masala, or spinach) and serve with sambar to add fibre and more pulses.

Cuisine examples: IN — moong chilla, besan chilla (gram flour batter, no soak), dosa, idli, uttapam, adai, dhokla; IT — farinata (chickpea flour pancake); FR — socca; PL — racuszki (yeasted pancakes, Wikibooks).

Common faults

9.4 Polish and continental breakfasts

What it does: builds a cold or quick-cooked breakfast around fresh cheese, eggs, good bread and raw vegetables, the pattern of Polish and much of central European breakfast (Wikibooks: "simple, often meatless").

The science: fresh cheeses like twaróg and paneer are made by acid or bacterial curdling of milk (Sodha's paneer method, Source notes) and keep most of milk's protein and calcium. Rye bread gets its dense, moist crumb from pentosans (gums) that hold water instead of gluten, and its sourness from sourdough fermentation, which rye needs to stop its enzymes breaking down the starch (Chemistry of Cooking ch. 31; Bertinet's rye bread).

Your equipment: triply pan for eggs; OTG to toast bread or bake racuszki in batches; stand mixer for rye and sourdough loaves (Part 6).

Five breakfasts

Nutrient note: wholegrain rye has more fibre and a gentler blood-sugar response than white bread; fresh cheese adds protein to slow digestion (Chatterjee's protein-first breakfast). Raw radish, cucumber, tomato and herbs add vitamin C and plant variety with no cooking losses. Lacto-fermented pickles (ogórki kiszone, Part 7.3) are a fermented food Spector would count; vinegar pickles are not.

Common faults

9.5 Building the plate

A healthy everyday plate is built from a few parts the techniques above already deliver. Chatterjee and Spector agree on most of it; where they give different targets, both are shown, and both stress that nutrition is personal.

How the techniques help: pressure-cooked dal and steamed or stir-fried vegetables keep the most nutrients (4.2, 4.3, 5.2); a tadka adds spices with their fat-soluble compounds (5.3); batch-made staples (tomato masala, dahi, sprouts, idli batter) make a 15-minute plate possible on weekdays.

A note on evidence: plant diversity, fibre and whole foods have strong support. Time-restricted eating and fermented-food benefits have promising but more modest evidence, and Chatterjee advises caution with eating windows for some people (his course flags it; check with a doctor if you have a medical condition, are pregnant or have a history of disordered eating).

The classical repertoire every cook builds on: Escoffier's mother sauces and their families, butter sauces, French onion soup, the potato classics, and two Italian pillars, pizza and pasta. It draws on Koffmann, who teaches that one sauce becomes another by switching ingredients in and out, Marco Pierre White, Bertinet, the textbooks and Wikibooks. Foundations (stocks, thickening, emulsions) are in Part 3.

10.1 The mother sauces and their families

What it does: five base sauces, codified by Escoffier, each the parent of dozens of others. Learn the five methods and the variations follow by adding or swapping one ingredient (Koffmann calls them "mother sauces" in his hollandaise lesson).

The science: each mother sauce uses one thickening principle from Part 3.3: roux (starch gelatinisation) for béchamel, velouté and espagnole; reduction and gelatin for demi-glace; purée and reduction for tomato; emulsion (egg-yolk lecithin) for hollandaise (3.4). Roux cooked longer turns darker and nuttier but thickens less, because heat breaks starch into dextrins (2.4).

Your equipment: heavy triply saucepan; balloon whisk; fine sieve; bain-marie bowl for hollandaise; stocks from Part 3.2.

The five and their children

Nutrient note: roux and butter sauces are rich; a little goes a long way. Lighter modern options from the same families: a reduced stock thickened only by reduction (5.1), a tomato sauce, or a velouté made with vegetable stock and finished with yogurt off the heat instead of cream.

Common faults

10.2 Butter and reduction sauces

What it does: quick, modern French sauces made in minutes from a reduction and butter, without roux: beurre blanc for fish and vegetables, red-wine reductions for meat, browned butter, and pan gravy.

The science: reduction concentrates flavour, acidity and gelatin (5.1). Cold butter whisked into a small amount of hot, acidic reduction forms an emulsion: butter's own milk proteins and the reduction's solids hold the fat in droplets. It is stable only between about 30 and 60 °C; hotter and the fat separates, colder and it sets. Browned butter (noisette) is butter heated until its milk solids toast at around 150–160 °C, a Maillard reaction (2.2).

Your equipment: small heavy triply saucepan; whisk; probe; cold butter cut in 1–2 cm cubes; the sim burner.

Four sauces

Nutrient note: butter sauces are high in saturated fat; serve 1–2 tbsp per portion. Reductions of stock and wine carry most of the flavour with little fat; most alcohol cooks off in a long reduction but some remains in short ones.

Common faults

10.3 French onion soup (soupe à l'oignon gratinée)

What it does: turns a kilo and a half of onions, stock, bread and cheese into a deep brown, sweet, savoury soup under a bubbling cheese crust. It is the purest lesson in browning onions, the same skill as Indian birista and bhuna (5.2; Jaffrey: take onions to rich reddish-brown or the dish will be pale and weak).

The science: onions are about 90% water and rich in sugars. Slow cooking first evaporates the water, then caramelises the sugars and drives Maillard reactions with the onion's amino acids (2.2), producing sweetness, colour and savoury depth. The browned film that forms on the pan base (fond) is the most flavourful part: deglazing with a splash of water every time it forms puts it back into the onions. A pinch of baking soda speeds browning (alkaline pH, 2.2) but makes onions softer and slightly less sweet, so use it sparingly if at all.

Your equipment: wide, heavy triply casserole (more surface = faster evaporation); wooden spatula; the large burner then the sim; oven-proof soup bowls; OTG top element on maximum for gratinating.

Method (serves 6)

1. Slice 1.5 kg onions thinly from root to tip (pole to pole slices hold their shape).
2. Sweat: 40 g butter + 1 tbsp oil, onions and 1 tsp salt, covered on medium 10–15 min until they collapse and release water.
3. Brown: uncover; medium-low, stirring every few minutes, for 45–60 min (longer at altitude). Each time a brown film forms on the base, add 2–3 tbsp water and scrape. Stop at a deep, even chestnut brown.
4. Deglaze: 1 tbsp flour optional (body); 150 ml dry white wine or 2 tbsp brandy; boil off.
5. Simmer: 1.5 L hot brown stock (Koffmann's veal stock is classic; chicken or beef work; MPW's mushroom stock for vegetarians, 3.2) with thyme and bay, 20–30 min. Season; a few drops of sherry or wine vinegar brightens it.
6. Gratinée: toast thick slices of baguette until dry (OTG 180 °C, 10 min). Ladle soup into oven-proof bowls, float a croûte, cover with 40–50 g grated Gruyère (or Emmental, or a mix with Parmesan) per bowl.
7. Under the OTG top element on maximum, top shelf, 3–5 min until bubbling and browned in patches.

Pressure-cooker shortcut: onions, butter, salt and 60 ml water, 1 whistle and 15 min on low, natural release; then boil off the liquid uncovered and brown 15–20 min. Not quite as deep, but about half the time.

Nutrient note: onions bring prebiotic fibre (fructans) that Spector counts as gut-friendly; slow cooking keeps the minerals in the soup. The cheese and butter make it rich; a smaller cheese crust or a croûte rubbed with garlic and olive oil lightens it.

Common faults

10.4 Classic French potato techniques

What it does: the potato is the most-taught vegetable in classical French cooking: MPW recalls five potato dishes on the menu every day of his apprenticeship. Part 8.1 has full methods for mash (Koffmann), rösti, gratin dauphinois, pommes boulangère and chips (MPW). This page adds the other classics and shows how they relate.

The science: two choices decide every potato dish (8.1): floury or waxy, and keep or wash off the surface starch. Washing gives separate, crisp pieces (chips, sautées); keeping the starch glues layers together (MPW: don't wash slices for pommes Maxim, the starch is "the necessary cement"). Drying slices on a cloth lets them brown instead of steam. Butter browns potatoes beautifully but its milk solids burn, so classical recipes use clarified butter or ghee (7.2).

The classic family

Your equipment: mandoline with guard; ricer; heavy triply sauté pan; ovenproof pan or dish for Anna and fondantes; piping bag for duchesse; OTG 200 °C.

Nutrient note: potatoes boiled or steamed in their skins keep the most vitamin C and potassium (8.1); classical dishes add a lot of butter or cream, so pair them with green vegetables or salad (MPW: "Man cannot live on potatoes alone"). Pommes sautées from cooled potatoes contain more resistant starch (2.4).

Common faults

10.5 Pizza in the OTG (Bertinet)

What it does: makes Neapolitan-style pizza with a crisp, blistered base and a slightly chewy crumb in a home oven that tops out around 230–250 °C (a wood-fired oven runs at 450 °C or more).

The science: a pre-ferment (Bertinet's biga) and a slow, cold rise develop flavour, a little acidity and extensible gluten, so the dough stretches thin without tearing (Bertinet: crisp outside, slightly chewy inside). A thoroughly preheated stone or heavy tray stores heat and delivers it fast to the base, mimicking a pizza oven floor; the top element browns the cheese. Wet toppings (fresh buffalo mozzarella, watery sauce) steam the dough, so Bertinet uses firm mozzarella and sieved tomatoes.

Your equipment: stand mixer; scale; baking stone, steel or upturned heaviest tray on the top-middle shelf; pizza peel or a flat, rimless tray dusted with semolina; OTG on maximum, top and bottom elements. A 36 L oven bakes one pizza of about 22–26 cm at a time.

Bertinet's dough (makes 6–7 pizzas, summarised)

1. Biga: 125 g strong white flour, 5 g fresh yeast, 125 g warm water; rest at least 3–4 h at room temperature (or overnight in the fridge) until bubbly and creamy.
2. Dough: 1 kg strong white flour, 20 g coarse semolina, 25 g salt, 20 g fresh yeast, 650 g cool water (mixer), 30 g olive oil, all the biga. Mixer on slow 4 min, then medium until smooth and elastic.
3. Rest: 3–6 h at room temperature, or overnight up to 48 h in the fridge (better texture and flavour).
4. Divide into 200 g pieces; shape into balls; rest on a semolina-dusted oiled tray. (Balls freeze well; shape bases after thawing.)

Method: bake

1. Preheat the oven with the stone or tray at 230 °C or as high as it goes, for at least 45–60 min.
2. Dust the surface with half flour, half semolina. Press each ball out from the centre with the heel of your hand, then stretch to a 20–22 cm circle; don't roll (it knocks out the gas).
3. Onto a semolina-dusted peel; thin layer of sieved tinned plum tomatoes (Bertinet pushes them through a fine sieve or blitzes them); slices of firm mozzarella; torn basil, oregano, salt, pepper, olive oil.
4. Slide onto the stone. If preheated to 240–250 °C, drop to 230 °C; bake 6–8 min at the top of the oven until the edges are golden and crisp.
5. For more top colour, switch to top element only for the last 1–2 min.

Nutrient note: a thin base with a light topping of tomato (cooked tomato gives more lycopene, 2.5), vegetables and a moderate amount of cheese is a balanced meal; replacing 20–30% of the flour with wholewheat adds fibre. Long fermentation may make the base easier to digest (6.3).

Common faults

10.6 Fresh pasta

What it does: turns flour and eggs (or semolina and water) into silky ribbons, sheets and filled pasta that cook in minutes.

The science: egg supplies the liquid, protein and fat. Kneading develops gluten for elasticity (2.4); resting relaxes it so the dough rolls thin without shrinking back. Durum semolina has strong, less stretchy gluten and gives a firmer bite, while soft flour (Italian "00", or Indian maida) gives silkier pasta. Fresh pasta has no dried, set starch surface, so it cooks in 2–5 min and absorbs sauce readily; it suits delicate butter, cream and light tomato sauces (Wikibooks: Pasta).

Your equipment: scale; stand mixer with the dough hook (or a food processor, as Wikibooks suggests, or hands); rolling pin and a large board, or a pasta-roller attachment if your mixer takes one; sharp knife; a broom handle across two chairs, or floured trays, for drying; large pot of boiling salted water.

Method: egg pasta (Wikibooks, 3 servings, about 375 g)

1. Dough: 300 g plain flour or durum semolina (or half and half) with 1 tsp salt. Beat 3 eggs with 1 tbsp olive oil; work into the flour (processor, mixer or a well on the board) until it forms a ball, adding water a teaspoon at a time only if needed. General ratio: 100 g flour per egg.
2. Knead 10 min on a lightly floured surface until smooth and elastic (by hand or mixer hook on low).
3. Rest wrapped, 30 min in the fridge; knead briefly again as it warms.
4. Roll by hand: half the dough at a time; roll, turn 90°, roll again, repeatedly, until paper-thin (you can see your hand through it), flouring if it sticks. Rest the sheet 10 min.
5. Or roll by machine: widest setting 5–6 times, folding in thirds each time, then thinner settings one by one to about 1 mm.
6. Cut: dust, roll up loosely and slice: 3 mm (tagliarini), 6 mm (tagliatelle, fettuccine), 2 cm (pappardelle), 10 cm (lasagne). Shake out the ribbons.
7. Cook in plenty of boiling salted water (about 10 g salt per litre) 2–5 min until al dente (Wikibooks allows up to 5–10 min for thicker hand-rolled pasta); at altitude allow a little longer. Keep in the fridge up to 24 h, floured, or freeze.

Filled pasta (ravioli, tortellini): roll sheets to about 1 mm; place teaspoons of filling (ricotta or paneer with spinach and nutmeg; mushroom duxelles, 8.3; pumpkin) 4 cm apart; brush around with water; cover with a second sheet; press out all air; cut. Cook 3–4 min; serve with beurre noisette and sage (10.2).

Eggless semolina pasta (orecchiette, cavatelli): 200 g durum semolina + about 100 ml warm water, kneaded 10 min, rested 30 min; roll into ropes, cut 1 cm pieces, drag each with a knife tip and press over the thumb into "little ears". Cook 4–6 min. Atta can replace some semolina for an Indian-pantry version.

Nutrient note: egg pasta adds protein and fat compared with plain dried pasta; swapping a third of the flour for wholewheat or semolina adds fibre and slows digestion. Pair with vegetables and legumes (pasta e fagioli) for a balanced plate.

Common faults

10.7 Dried pasta and the classic sauces

What it does: cooks dried pasta al dente and binds it with a sauce that coats every strand instead of pooling in the bowl.

The science: dried durum pasta has a dense, set protein network that keeps it firm (al dente) while the starch inside gelatinises (2.4). Pasta water carries dissolved starch that acts as a thickener and helps oil, butter and cheese stay emulsified (3.4); finishing the pasta in the pan with the sauce and a splash of this water (mantecatura) is what makes Italian sauces cling. Cheese and egg sauces must stay below the point where proteins clump: egg yolks thicken from about 65 °C and scramble above about 75 °C (2.3); hard cheeses go stringy if overheated.

Your equipment: large pot (Wikibooks: about 4 L water per 200 g pasta) on the large burner; wide triply sauté pan for finishing; tongs; a mug to save pasta water; microplane for cheese.

Cooking dried pasta (4.6 has the basics)

1. Rolling boil, 10 g salt per litre; add pasta; stir in the first minute.
2. Start tasting 2 min before the packet time (add 1–2 min at altitude). Dried pasta generally takes 9–12 min (Wikibooks).
3. Save a mugful of water; drain 1 min early; finish in the sauce.

Four classic sauces (2 servings, 200 g pasta)

Wikibooks' Italian page also lists alle vongole (clams), puttanesca (tomato, olives, capers, anchovy) and pasta e fagioli for further practice.

Indian pantry versions: masala pasta with a bhuna tomato base (5.2); vermicelli upma or seviyan kheer use the same dry-roast-then-cook principle as upma (9.2).

Nutrient note: al dente pasta digests more slowly than soft pasta; wholewheat pasta adds fibre. A 75–100 g dry portion per person with plenty of vegetables, pulses or fish keeps the plate balanced. Carbonara uses lightly cooked eggs: use very fresh eggs.

The North Indian masala sequence

Four of her braises (chicken moghlai p. 107, kheema p. 136, lamb with spinach p. 137, roghan josh p. 140) follow the same nine-stage order, and the order is the technique: each stage needs a different temperature, and later wet ingredients stop earlier browning. Use a heavy triply pot or kadai.

Variants. Roghan josh (p. 140) adds dry-roasted cumin, coriander, coconut and almonds ground into the paste, which thickens and darkens the sauce. Lamb with whole spices (p. 141) skips the paste: meat braises with whole spices and its own juices until only oil and a clinging sauce remain. Kheema (p. 136) fries the mince 7–8 min, breaking lumps, before simmering 1 hour.

Her core Indian techniques

IC's thesis is that Indian technique is mostly about coaxing different flavours out of the same spices (whole, ground, roasted or fried) and thickening sauces with onion, garlic, ginger, yogurt and tomato instead of flour. She also insists on full mise en place, because a masala is cooked in one continuous sweep.

Pulses (IC ch. 6, SBS p. 187)

• Always cooked with at least one of ginger, asafoetida or turmeric, traditionally for digestibility.
• Wash in several changes of water. Whole beans: soak overnight, or boil 2 min and soak 1 hour in that water. Fresher pulses cook faster.
• Split dals froth; keep the lid ajar (in the pressure cooker, fill no more than half).
• Moong dal: about 280 g dal to 1.2 L water, skim the froth, simmer 50–60 min with turmeric, garlic and ginger to between pea soup and porridge thickness; salt and lemon at the end, then the tarka.
• Chickpeas: soak overnight with a little baking soda, simmer about 1 hour, keep some cooking liquid for the sauce. Nutrient note: alkali speeds softening but destroys some thiamine (vitamin B1); a pressure cooker gets the same softness without it.
• Dal + grain + yogurt makes a complete protein, as she notes and nutrition science supports.

Rice (IC ch. 8, SBS pp. 190–195)

• Wash in several changes of water to remove milling starch, then soak 30 min so grains stick less.
• Liquid ratio by volume: never more than 1½ : 1, and 1⅓ : 1 for soaked rice.
• Sauté soaked basmati gently, or the fragile grains break.
• Heavy pot, tight lid; seal with foil under the lid if it fits loosely. Very low heat about 25 min, or a 170 °C oven for 25 min. Do not lift the lid.
• Undercooked top layer means steam is escaping: cover it with cooked rice from below, add 1–2 tbsp water, seal with foil, 10 min more on very low.
• Pullao: fry soaked rice 7–8 min until translucent, add hot stock, cook until the surface looks dry, then cover and finish in a 160 °C oven for 20–25 min and rest 10 min (SBS p. 195).
• Saffron: dry-roast briefly, crumble into 2 tbsp warm milk, soak 20–30 min, then drizzle over the rice in streaks.

Breads (IC ch. 7): chapati dough is soft; roll with plenty of dry flour; cook on a preheated tava or heavy pan (preheating keeps it from going hard), then puff directly over a low gas flame. Pooris deep-fry best in a karhai, which needs the least oil for depth.

General techniques (SBS Techniques chapter)

SBS pp. 12–19 covers methods shared across Indian and Far Eastern cooking. Each maps onto your equipment as below.

Home staples and ingredient preparation

Jaffrey and Meera Sodha (Made in India: Cooked in Britain, Penguin, epub in the filtered collection; MI below) give compatible methods for the staples an Indian kitchen makes itself. Where they differ, both are shown.

Chapatti method compared. IC: soft dough, plenty of dry flour, preheated tava, then puff directly over a low gas flame. MI: 450 g atta, ½ tsp salt, 3 tbsp oil rubbed in, about 300 ml hot water, knead 6–8 min to soft and pliable; roll to 16 cm; cook 30–40 s a side on a medium-high pan, then flip twice more, pressing so it puffs. MI's fix for stiff dough: poke holes, add 1–2 tbsp hot water, rest, knead again, and cook hotter and shorter.

Worked example: Jaffrey's lamb biryani (pakki dum)

This recipe chains almost every technique above into one dish: masala sequence, parboiled rice and oven dum. It is the template for Part 4.5. Quantities serve about 6; method summarised from MasterClass.

Food-safety note: the rice sits warm for a long time in this method, so serve it hot and refrigerate leftovers within an hour (Part 1.3).

Two biryani methods compared

All three Food & Wine PDFs in the filtered collection are Jaffrey recipes. Her chicken biryani uses the same pakki (cooked-meat) dum method as the lamb, but faster and hotter, because chicken needs less braising.

Both leave a well in the centre of the rice down to the bottom, which lets steam rise evenly through the mound. OTG note: a 36 L oven fits a 24–26 cm casserole on the lowest shelf; use your Test 3 offset to hit the true temperature.

Tandoori chicken on a grill or in your OTG

Jaffrey's simplified tandoori (Food & Wine) uses a two-stage marinade and fierce heat. About 1.1 kg skinless, bone-in thighs and drumsticks:

1. Slash to the bone: two 2–3 cm diagonal cuts on each side of each piece, not starting at an edge. Marinade then reaches the centre, and the meat cooks more evenly.
2. Acid and salt first: squeeze 2 lemons over, rub in 2 tsp salt, including into the slits; rest 20 min. This seasons the meat deeply before the yogurt goes on.
3. Yogurt paste: blend 180 g yogurt, ½ onion, 5 garlic cloves, 2 cm ginger, ½ green chilli and 2 tsp garam masala until smooth (\~3 min). Coat, working it into the slits; refrigerate 5–24 h.
4. Cook hot: over very hot charcoal, basting with melted butter (\~110 g), 10 min a side, then turn for about 12 min more until lightly charred.
5. Finish: lemon wedges; serve with naan.

Your equipment: no charcoal needed. Use the OTG at its highest setting (230–250 °C), top element on, chicken on a rack over a foil-lined tray on the upper shelf. Turn once and baste; about 25–30 min. Pull at 74 °C in the thickest part (80–85 °C in thighs for tenderness). Her recipe deliberately omits red colouring; Kashmiri chilli is the traditional source of the colour.

Green lentil curry: tarka paste added at the end

Jaffrey's green lentil curry (Food & Wine) reverses the usual order: the spice base is cooked separately and stirred into finished lentils, like a tarka.

1. Wet spice paste: 1 tsp grated ginger, 1 mashed garlic clove, 2 tsp ground coriander, 1 tsp ground cumin, 60 ml water.
2. Spice base: heat 3 tbsp oil until shimmering; ¼ tsp cumin seeds about 5 s until sizzling; 1 minced shallot about 1 min until lightly browned; the paste about 2 min until most liquid evaporates; 1 tbsp tomato paste + 1 tbsp water about 1 min until thick.
3. Lentils: \~240 g whole green lentils + ¼ tsp turmeric + 1.2 L water; boil, then partly covered on low 20 min until barely tender.
4. Vegetables: add 115 g green beans (2 cm lengths), 115 g finely chopped kale, 1 sliced carrot, most of a cup of chopped coriander, ½ tsp cayenne, salt; 15 min until tender.
5. Finish: scrape in the spice base and remaining coriander; simmer 5 min.

Why it works: whole green lentils keep their shape, so the dish stays chewy, not porridge-like. Frying the wet paste until the water is gone lets the ground spices cook in oil instead of stewing. Nutrient note: the vegetables cook in the curry liquid, so the water-soluble vitamins that leach out are eaten, not drained. Pressure cooker: lentils + turmeric + 1 L water, first whistle then about 5 min on low; then add the vegetables and simmer uncovered.

At a glance

Extra-creamy scrambled eggs (J. Kenji López-Alt)

Why it works: a little starch dispersed in the eggs gets between the proteins as they set, so curds stay tender and don't squeeze out water, at any doneness. Kenji notes potato or tapioca starch works at slightly lower temperatures than cornflour, giving a slightly more tender result. It is the same principle as a little cornflour protecting a custard from curdling (3.3, 7.1).

Method (2 servings)

1. Whisk 2 tsp potato starch, tapioca or cornflour with 1½ tbsp water until smooth. Add half of 55 g cold butter cut in 5 mm cubes, then 4 eggs and a pinch of salt; whisk until frothy (butter lumps remain).
2. Plate ready by the stove. Heat 1 tbsp water in a 25 cm non-stick pan on medium-high until it has just evaporated (his built-in temperature test); immediately add the rest of the butter and swirl about 10 s until foamy, not brown.
3. Add the eggs; push and fold for 1–2 min until slightly less done than you want; plate at once. Fast stirring gives fine, soft curds; slow stirring gives large, fluffy curds. For 2 eggs, 15–30 s; for 8 eggs, 3–4 min, in a bigger pan.

Kitchen notes: works with cornflour from the pantry. Replace the water with milk for even creamier eggs (Kenji's option). For a masala version, fold in Sodha's chopped spring onion, green chilli and coriander at the end (9.1).

Everyday pancakes (Mark Bittman)

Why it works: a classic muffin-method batter (6.6): dry and wet mixed separately, then combined only until the flour is moistened, lumps and all, so little gluten forms and the pancakes stay tender. Baking powder starts working when wet and again with heat.

Method (4–6 servings)

1. Preheat a tava or large pan on medium-low.
2. Mix 250 g plain flour, 2 tsp baking powder, ¼ tsp salt, 1 tbsp sugar (optional).
3. Beat 2 eggs into 360 ml milk, then 2 tbsp melted, cooled butter (optional). Stir gently into the dry mix just until moistened; add milk up to 480 ml total if thick.
4. Butter or oil the pan; when the foam subsides or oil shimmers, ladle in batter. Flip when bubbles rise to the surface and the base is brown, 2–4 min; cook the second side until lightly browned. The first batch needs more heat than later ones.
5. Keep warm on a plate in the OTG at its lowest (about 95 °C) for up to 15 min.

Kitchen notes and nutrition: Bittman suggests wholewheat or buckwheat flour and fruit as variations: use half atta, add grated apple or banana and skip the sugar. Serve with dahi and fruit for protein (9.5). At altitude, cut baking powder to about 1½ tsp if they over-rise and collapse (1.4).

Jordan Marsh's blueberry muffins (Marian Burros)

Why it works: despite the name, this uses the creaming method (6.6), not the muffin method: butter and sugar beaten until light trap air, giving a cake-like, even crumb. Crushing some of the berries into the batter adds moisture and colour so the muffins stay soft for longer; a sugar sprinkle gives a crisp top. Burros advises storing them uncovered, or they turn too moist by the second day.

Method (12 muffins)

1. Oven to 190 °C (170 °C fan, Appendix B); line a 12-hole muffin tin.
2. Cream 115 g soft butter with 250 g sugar until light (stand mixer, paddle, 3–5 min).
3. Beat in 2 eggs one at a time, then 1 tsp vanilla.
4. Sift 250 g plain flour, ½ tsp salt, 2 tsp baking powder; add alternately with 120 ml milk.
5. Crush about 75 g of the blueberries (½ cup) with a fork and mix in; fold in the remaining berries (about 300 g in total).
6. Fill the cases; sprinkle 3 tsp sugar over the tops; bake 30–35 min until golden and a skewer comes out clean.
7. Cool at least 30 min before eating; store uncovered.

Kitchen notes: frozen blueberries work: fold them in frozen (thawed ones streak the batter). Local alternatives: chopped mango with cardamom, or mulberries in season. In a 36 L OTG, bake on the middle shelf and rotate the tin halfway (Test 3). At altitude, reduce baking powder to about 1½ tsp and sugar slightly (1.4). Health: these are cake; cutting the sugar by a quarter usually works.

Creamy macaroni and cheese (Julia Moskin)

Why it works: no pre-boiling. Uncooked pasta bakes in a blended cheese-and-milk sauce, absorbing the liquid while its starch thickens the sauce (2.4, 10.7). Puréed cottage cheese and dry mustard keep the sauce smooth and emulsified rather than greasy; covering for the first half keeps the moisture in, uncovering browns the top (gratiner, 10.8).

Method (6–8 servings)

1. Oven to 190 °C, rack in the upper third. Grease a 23 cm baking dish with 1 tbsp of 2 tbsp butter.
2. Blend 225 g full-fat cottage cheese, 480 ml whole milk, 1 tsp dry mustard, pinch each of cayenne and nutmeg, salt and pepper.
3. Reserve a handful of cheese; in a large bowl combine the rest of 450 g grated sharp Cheddar, the milk mixture and 225 g uncooked elbow macaroni.
4. Pour into the dish; cover tightly with foil; bake 30 min.
5. Uncover, stir gently, scatter the reserved cheese and dot with the remaining butter; bake 30 min more until browned. Rest 15 min before serving.

Kitchen notes: cottage cheese is hard to find in India: blend fresh, unpressed paneer (7.2) with a few spoons of dahi to the same weight, or use ricotta. Use the OTG's upper-middle shelf; switch to top element only for the last 5 min if it needs colour. Health: rich; serve a small portion with a big green salad, or stir in blanched broccoli or peas before baking.

Roasted chicken Provençal (Sam Sifton, after Steven Stolman)

Why it works: a combination roast. Floured chicken sits high in a hot roasting tray so its skin crisps in dry heat, while underneath shallots, garlic and lemon soften and caramelise in a shallow bath of vermouth and rendered fat that becomes the sauce (5.5 above, 4.4 below). Flour helps the skin brown and slightly thickens the pan juices (Koffmann uses the same trick for coq au vin).

Method (4 servings)

1. Oven to 200 °C. Season 4 chicken legs or 8 bone-in, skin-on thighs with about 1 tsp table salt and 1 tsp black pepper; dredge lightly in 60–90 g flour, shaking off the excess.
2. Swirl 3 tbsp olive oil in a large roasting tray; add the chicken; sprinkle with 2 tbsp herbes de Provence. Scatter a quartered lemon, 8–10 peeled garlic cloves and 4–6 halved shallots around; pour in 80 ml dry vermouth.
3. Roast 25–30 min; baste with the pan juices; roast 25–30 min more until very crisp and cooked through (thigh 80–85 °C, 1.2).
4. Serve in the tray with thyme sprigs, with baguette or a green salad to mop up the sauce.

Kitchen notes: in a 36 L OTG use the largest tray that fits (6–8 thighs), middle shelf, fan on; rotate halfway. No vermouth? Use dry white wine, or stock with a squeeze of lemon (Appendix C). Small Indian red onions can replace shallots. Herbes de Provence = dried thyme, rosemary, oregano, a little fennel seed. Health: remove the skin before eating for less fat; the garlic, shallots and lemon add flavour without extra salt.

Marry Me chicken (Naz Deravian)

Why it works: thin, even cutlets cook through before the outside overbrowns; flour helps them brown and later thickens the sauce. The sauce is a classic pan sauce (5.1, 10.2): garlic, tomato paste fried until darker (Maillard), stock to deglaze and reduce, cream at a gentle simmer, Parmesan to thicken. A cousin of murgh makhani, with sun-dried tomatoes instead of a tomato masala.

Method (4 servings)

1. Slice 3 large chicken breasts (about 1 kg) horizontally into 6 cutlets; chilling them 20 min in the freezer makes this easier. Pat dry, season, dust with 30 g flour.
2. Heat 3 tbsp olive oil on medium-high, lower to medium, add 3 tbsp butter; cook cutlets in batches until golden, about 5 min, then 4–5 min on the second side. Set aside. (Probe: 74 °C.)
3. Low heat: 3 chopped garlic cloves 1–2 min; 1 tbsp tomato paste about 2 min until it darkens; ½ tsp dried oregano, chilli flakes.
4. Medium heat: 240 ml low-sodium chicken stock; simmer, scraping up the fond, until reduced by half (about 5 min).
5. Add 120 ml cream; keep at a gentle simmer about 3 min until slightly thickened (watch it; lower the heat if needed). Stir in 40 g grated Parmesan and about 40 g sliced oil-packed sun-dried tomatoes; more cream if you like.
6. Return the chicken for about 4 min to warm through; basil on top.

Kitchen notes: triply sauté pan preheated to the Test 5 skating-drop stage before the oil goes in. For a lighter sauce, replace half the cream with whole milk thickened with 1 tsp cornflour, or finish with hung curd off the heat (7.2). Serve with a green salad, rice or pasta.

Coq au vin (Melissa Clark)

Why it works: an overnight wine marinade seasons the chicken deeply; drying it before browning lets it sear instead of steam (5.1); the marinade is then boiled and reduced by half to drive off raw alcohol and concentrate flavour before the braise (4.4). Clark uses all dark meat, which stays succulent over an hour's simmering (white meat would dry out: add breasts only for the last 30 min). The garnish of pearl onions, mushrooms and lardons is cooked separately so it stays browned and firm, the same idea as Koffmann's garniture grand-mère.

Method (4 servings)

1. Marinate: season 1.35 kg chicken legs and thighs with about 1 tsp table salt and pepper; cover with 720 ml hearty red wine, a bay leaf and 1 tsp thyme; refrigerate at least 2 h, ideally overnight.
2. Lardons: 115 g diced lardons, pancetta or bacon on medium-low in a heavy casserole until the fat renders and they crisp, 10–15 min; lift out, keep the fat.
3. Brown: lift the chicken from the wine (keep the marinade), pat very dry, brown in the hot fat in batches, 3–5 min a side; set aside.
4. Vegetables: diced onion, carrot and half of 225 g mushrooms with a pinch of salt, about 8 min until lightly browned, scraping up the fond.
5. Build: 2 minced garlic cloves and 1 tsp tomato paste 1 min; 1 tbsp flour 1 min. Off the heat, add 2 tbsp brandy to a cleared side of the pot and ignite it (or simply cook it down 1 min). Add the marinade, boil and reduce by half (to about 360 ml), about 12 min, skimming the foam.
6. Braise: chicken, juices and half the lardons back in; covered on low 1 h, turning halfway; uncovered 15 min to thicken. Season.
7. Garnish: 225 g peeled pearl onions in butter and oil with a pinch of sugar, covered on low 15 min, shaking; then the rest of the mushrooms on medium-high until browned, 5–8 min.
8. Croutons: bread triangles fried in butter and oil until golden; dip in the sauce, then chopped parsley.
9. Combine the garnish and remaining lardons with the chicken; parsley and croutons on top.

Compared with Koffmann (4.4): Koffmann skips the marinade and flambé, sears floured chicken, adds wine and veal stock and finishes in a 180 °C oven for only 15–20 min; Clark's version is longer, deeper and wine-forward. Kitchen notes: the sim burner holds the hour's simmer; the pressure cooker cuts step 6 to about 5 min on low (4.3) but the sauce will need longer reduction. Small Indian onions (sambar onions) stand in for pearl onions. Flambé safety: off the heat, extractor off, long match, lid at hand (10.8).

Pumpkin oatmeal cookies (Yossy Arefi)

Why it works: creaming butter with brown and white sugar for a full 5 min beats in air (6.6); pumpkin purée adds moisture, so the cookies bake up soft and cake-like rather than crisp and barely spread. The oats and flour are mixed in just until combined to keep them tender. Brown sugar's molasses keeps them moist and chewy.

Method (about 30 cookies)

1. Oven 180 °C (160 °C fan); two trays lined with baking paper; racks in the top and bottom thirds.
2. Cream 113 g soft butter, 150 g light brown sugar and 50 g white sugar until light and fluffy, 5 min.
3. Mix in 115 g pumpkin purée, 2 tsp pumpkin spice, 2 tsp vanilla and about ½ tsp table salt.
4. Add 135 g rolled oats, 128 g plain flour and ½ tsp baking soda; mix on low until moistened, then finish by hand just until combined.
5. Heaped tablespoons 5 cm apart; press slightly flat with damp fingers (they barely spread).
6. Bake 14–16 min until matte and just golden at the edges, rotating and swapping the trays halfway. Cool on the trays.
7. Optional frosting: 113 g soft butter, 120 g icing sugar, 1 tbsp pumpkin purée, 1 tsp pumpkin spice, 1 tsp vanilla, pinch of salt, beaten 3 min until fluffy; about 2 tsp per cookie.

Kitchen notes: make the purée from Indian red pumpkin (kaddu): steam or pressure-cook chunks (1 whistle), drain well, mash smooth; excess water makes the cookies cakey and pale. Pumpkin spice: 3 parts cinnamon, 1 ginger, ½ nutmeg, ¼ cloves (Arefi: cinnamon alone works). In a 36 L OTG you may fit only one tray at a time: bake on the middle shelf and skip the swapping. Health: oats and pumpkin add fibre and beta-carotene; skip the frosting and cut the sugar by a quarter for an everyday version.

Conversion and lookup tables. All weights are approximate for spooned-and-levelled measures; for anything that matters (baking, rice, dal), weigh. Cup = 240 ml; tablespoon = 15 ml; teaspoon = 5 ml.

A. Cups and spoons to grams

Recipes from the US (Food & Wine, MasterClass) use cups; UK and Indian books (Jaffrey's IC, Sodha, Bertinet) use grams. Values are typical for spooned-and-levelled ingredients.

Salt warning: US recipes often specify kosher salt, which is about half as dense as Indian table salt. Halve the volume when using table salt (e.g. the Food & Wine biryani's 3 tbsp kosher salt ≈ 1½ tbsp table salt).

Weights: 1 oz = 28 g; 1 lb = 454 g; 1 fl oz = 30 ml; 1 inch = 2.5 cm.

B. Oven temperatures

Set the dial using your own offset from Part 1 Test 3, not the numbers printed on the knob.

Converting a recipe to your OTG: recipes written for a conventional oven: reduce 10–20 °C with the fan on, or keep the temperature and shorten the time by about 10%. Recipes written for a fan oven (Bertinet, most modern UK books): use as written, fan on. In a 36 L cavity the food sits close to the elements, so check 5–10 min early, rotate trays, and use the lower shelf for tall cakes and loaves.

Sugar stages at altitude: subtract (100 − your boiling point) from every sugar-syrup temperature; at \~95.5 °C boiling point, soft ball is about 107–111 °C instead of 112–116 °C (Part 1.4).
