Toor dal

Red lentilsUse equal weight. Cooks considerably faster and breaks down into a softer, creamier consistency with an earthier taste.
Chana dalUse equal weight. Requires longer soaking and cooking; remains firmer with a nuttier bite and less starchy thickening.
Split mung beansUse equal weight. Cooks quickly to a lighter, more delicate, and silky texture.

Water

StockUse the same weight in savoury dishes; it adds body, so adjust salt.
MilkUse the same weight only in doughs or creamy dishes; it makes the result richer.
Coconut waterUse the same weight in curries or rice; it adds sweetness and a faint coconut taste.

Kashmiri chilli powder

Dried kashmiri chilliGrind deseeded dried pods to an equal weight of powder; gives identical vivid red colour and gentle warmth.
Red chilli powderUse 25% of the weight mixed with sweet paprika for colour; straight red chilli powder is substantially hotter and will make the dish fiery.
Chilli powderUse one-third of the weight; the sauce will be less intensely red and notably sharper in heat.

Ground turmeric

Ground gingerUse 50% of the weight. Mimics turmeric's warm, earthy, rhizome background, but provides none of the golden-yellow colour.
SaffronSteep a tiny pinch (0.1 g per 2 g turmeric) in 2 tbsp warm water; use to match the rich golden hue. Contributes an aristocratic, honeyed floral flavour rather than earthy bitterness.

Asafoetida

Garlic powderUse double the weight. Stir into hot oil just before adding wet ingredients; mimics the allium savoury background without the sulphurous edge.
Garlic pasteUse 2 g for every 0.5 g of asafoetida. Sauté in oil until the raw smell clears; adds moisture and sweet allium depth.

Fresh ginger

Ginger pasteUse equal weight. Sauté in hot fat until the raw allium smell disappears; slightly wetter, but provides identical warmth and pungency.
Ground gingerUse 20% to 25% of the weight (1 g for every 4 to 5 g fresh). Stir into the gravy; adds peppery heat and warmth, though it misses the crisp, zesty kick of raw root.

Green bird's eye chilli

Bird's eye green chilliUse the same weight; heat and flavour are very close.
Green chilliUse 1.5 to 2 times the weight; deseed for less heat. Larger chillies are more watery.
Fresh green chilliUse 1.5 to 2 times the weight; chop finely and adjust heat by tasting.

Coriander leaf


Tomato

Tomato puréeUse 40% to 50% of the fresh tomato weight mixed with a splash of water. Imparts a deeper red colour, thicker sauce, and slightly sweeter cooked flavour.
Plain yogurtUse 60% of the weight, whisked smooth and added on low heat. Provides rich body and sourness, though the gravy becomes paler and creamier.

Black peppercorn

Coarsely ground black pepperUse 75% of the weight. Add midway through simmering; spreads heat evenly through the dish instead of delivering isolated bursts.
Ground black pepperUse 50% of the weight. Stir in near the end of cooking; significantly darkens light gravies and provides an immediate, sharp bite.

Tamarind paste

Tamarind pulpUse 120–150% of the weight and strain; pulp is less concentrated, so simmer a little longer to thicken.
Tamarind extractUse 150–200% of the weight and reduce gently; extract is already diluted.
Lime juiceUse 60–70% of the weight with a pinch of jaggery; sharper, so add near the end off the heat.

Rice

Basmati riceUse the same weight; rinse and soak as needed. Fluffier and drier, so use slightly less water.
Long-grain riceUse the same weight; similar behaviour, adjust water to your usual method.
Short-grain riceUse the same weight; stickier and softer, so reduce water and avoid stirring.

Vegetable oil

Peanut oilUse 1:1 by weight. Handles high-heat frying identically and introduces a very subtle, pleasant nuttiness.
GheeUse 1:1 by weight. Yields a much richer, authentic aroma and a glossy, heavier mouthfeel.
Mustard oilUse 1:1 by weight. Heat until smoking, then cool slightly before cooking to temper its intensely pungent, sharp mustard kick.

Black mustard seed

Mustard seedsUse equal weight. Pop in hot fat until they crackle and turn greyish; yields an almost identical nutty, pungent finish.
Yellow mustard seedsUse equal weight. Fry over medium heat; delivers a milder, sweeter pop and turns bitter quickly if the oil is excessively hot.

Curry leaf

Bay leafFry 1 bay leaf for every 5 curry leaves in hot oil; imparts a warm, woodsy background note, but misses the citrus-sulphury punch entirely.
Lime juiceAdd a small squeeze (about 5 ml per sprig of curry leaves) right before serving; provides sharp citrus top notes without the toasty, herbal aroma.
