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.

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.

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.

Mild dried red chilli

Dried kashmiri chilliUse the same weight; similar mild heat and good colour. Remove seeds if you want it milder.
Kashmiri red chilli powderUse half the weight of whole chilli (1 g powder for 2 g whole); add to hot oil briefly so it does not burn.
PaprikaUse the same weight; sweeter and milder, good for colour. Add a pinch of cayenne pepper if you need heat.

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.

Potato

EggplantUse equal weight. Cut into large chunks; cooks down much faster (10-12 minutes) and softens into the sauce rather than staying starchy and firm.
PaneerUse 80% of the weight. Cube and add in the last 5-10 minutes of cooking; adds rich dairy protein instead of starchy bulk.
Dried chickpeaUse 45% dry weight. Soak overnight and boil until fully soft before stirring into the sauce to simmer for 10 minutes.

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.

Aubergine

Baby aubergineUse the same weight; halve or quarter and cook 2–3 minutes longer. They hold their shape better in the sauce.
Small aubergineUse the same weight; slice or cube to the recipe's size. Similar flesh, slightly firmer.
Round aubergineUse the same weight; cube and salt for 10 minutes if the recipe does. It absorbs oil a little more.

Ground cumin

Cumin seedDry-roast briefly and grind finely; use equal weight (1:1). Imparts an even punchier, nuttier, toasty aroma than pre-ground cumin.
Ground corianderUse equal weight (1:1). Adds mild, lemony sweetness rather than cumin's smoky, earthy bite; curries will taste lighter and less savoury.
Black cumin seedsGrind finely; use 60% to 75% of the weight. Produces a darker, more complex, smoky-herbal flavour suited to rich gravies.

Ground coriander

Coriander seedsDry-roast lightly in a pan and grind to a fine powder; use equal weight (1:1). Offers a noticeably fresher, brighter citrus note.
Ground cuminUse 50% to 75% of the weight. Lacks the floral, citrusy profile of coriander and turns the gravy heavier, earthier, and darker.
Garam masalaUse 50% of the weight and stir in near the end of cooking. Adds warmth and depth since it contains ground coriander, but introduces stronger spices like clove and cinnamon.

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.

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.

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.

Jaggery

Granulated sugarUse 80% of the weight. Granulated sugar is sweeter by weight, but gives a cleaner, one-dimensional sweetness that lacks jaggery's caramel, molasses depth.
RaisinSoak and blend into a paste; use 100% to 120% of the weight. Adds rich, natural, fruity sweetness with complex, dark molasses notes that thicken the gravy.

Coriander

Coriander leafUse equal weight, chopped fresh and stirred in off the heat or used as garnish. Matches the citrus-herbal profile identically.
MintUse 40% to 50% of the weight; chop finely and add at the very end. Adds fresh herbal brightness, but shifts the aroma toward cool menthol.
