Don't have something?

King prawn

Tiger prawnUse the same weight; split or halve if large. Same sweet shellfish flavour, similar cooking time.
Large prawnUse the same weight; they may need 1 minute less cooking. Slightly less sweet.
Firm white fish filletUse the same weight, cut into chunks and add 2-3 minutes later. Flakes easily and lacks prawn juice.

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.

Malt vinegar

White malt vinegarUse the same weight; sharper and clearer; reduce salt slightly.
White vinegarUse 90% of the weight, diluted with 10% water; harsher, so taste.
Lime juiceUse the same weight; fresher sourness but no malt flavour; reduce salt.

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.

Curry leaves

Curry leafUse the same weight; tear and fry in oil as usual.
Lime leafUse 50% of the weight, torn; citrusy but not resinous.
Basil leavesUse the same weight; sweet and aniseed-like, but quite different.

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.

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.

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.

Coconut milk

Single creamUse equal weight; simmer gently over low heat to prevent curdling. Imparts a comparable rich texture, though it adds dairy richness without any coconut fragrance.
Cashew pasteWhisk 1 part cashew paste with 2 parts water to match the consistency, then use equal weight. Provides a thick, velvety body without coconut flavour.
Whole milkUse equal weight, but reduce other cooking liquids by 20% to compensate for the lower viscosity. The curry will be lighter and lack sweetness.

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.

Coriander leaf


Coconut

Fresh coconutUse equal weight freshly grated or diced. Delivers the identical sweet, milky taste and juicy texture.
Desiccated coconutUse 60% of the weight and soak in hot water or milk for 15 minutes before using. The finished dish will be slightly sweeter and less fibrous.
Dried coconutFinely grate and use 50% of the weight, soaked in hot water for 20 minutes. Yields a firmer chew and a denser, oilier coconut aroma.

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.

Garlic

Garlic pasteUse equal weight. Fry gently in oil or ghee with the ginger; incorporates smoothly into curries without visible minced bits.
Garlic powderUse 15% to 20% of the weight (about 1 g for every 5 to 6 g fresh cloves). Whisk into sauces; gives a savoury, toasted garlic flavour without raw pungency.
ShallotUse 1.5 times the weight, very finely minced. Sauté until golden; provides savoury allium sweetness, though it lacks garlic's pungent sulphur bite.

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.

Cumin seed

Ground cuminUse 70% of the weight; add with ground spices or sauce bases rather than hot oil tempering, where it scorches quickly and turns bitter.
Black cumin seedsUse equal weight for oil tempering. Delivers an earthy profile with an additional musky, smoky, and slightly bitter edge.
Fennel seedUse 60% of the weight for tempering; offers comparable warm aroma, but leans sweet and liquorice-like rather than savoury and earthy.
