Don't have something?

Vegetable or coconut oil
  • Sunflower oil

    Use the same weight. Neutral, no change to flavour.

  • Groundnut oil

    Use the same weight. Slightly nutty, suits Indian dishes.

  • Mustard oil

    Use the same weight but heat to smoking point first. Strong pungent flavour changes the dish.

Black mustard seed
  • Mustard seeds

    Use equal weight. Pop in hot fat until they crackle and turn greyish; yields an almost identical nutty, pungent finish.

  • Yellow mustard seeds

    Use equal weight. Fry over medium heat; delivers a milder, sweeter pop and turns bitter quickly if the oil is excessively hot.

Onion
  • Shallot

    Use equal weight, finely sliced. Shallots soften and brown faster, giving a slightly sweeter and more delicate base to curries.

  • Cabbage

    Use 80% of the weight, finely shredded and browned slowly with a pinch of asafoetida. Replicates the bulk and natural sweetness in gravies without allium.

Curry leaf
  • Bay leaf

    Fry 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 juice

    Add a small squeeze (about 5 ml per sprig of curry leaves) right before serving; provides sharp citrus top notes without the toasty, herbal aroma.

Green bird's eye chilli
  • Bird's eye green chilli

    Use the same weight; heat and flavour are very close.

  • Green chilli

    Use 1.5 to 2 times the weight; deseed for less heat. Larger chillies are more watery.

  • Fresh green chilli

    Use 1.5 to 2 times the weight; chop finely and adjust heat by tasting.

Fresh ginger
  • Ginger paste

    Use equal weight. Sauté in hot fat until the raw allium smell disappears; slightly wetter, but provides identical warmth and pungency.

  • Ground ginger

    Use 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 paste

    Use equal weight. Fry gently in oil or ghee with the ginger; incorporates smoothly into curries without visible minced bits.

  • Garlic powder

    Use 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.

  • Shallot

    Use 1.5 times the weight, very finely minced. Sauté until golden; provides savoury allium sweetness, though it lacks garlic's pungent sulphur bite.

Water
  • Stock

    Use the same weight in savoury dishes; it adds body, so adjust salt.

  • Milk

    Use the same weight only in doughs or creamy dishes; it makes the result richer.

  • Coconut water

    Use the same weight in curries or rice; it adds sweetness and a faint coconut taste.

Sea bream
  • Sea bass

    Use the same weight; reduce cooking by 1–2 minutes.

  • Pomfret

    Use the same weight; similar firm flesh, and score the skin if cooking whole.

  • Firm white fish fillet

    Use the same weight; reduce cooking by 2–3 minutes and handle gently.

Coconut milk
  • Single cream

    Use 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 paste

    Whisk 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 milk

    Use 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 pulp

    Use 120–150% of the weight and strain; pulp is less concentrated, so simmer a little longer to thicken.

  • Tamarind extract

    Use 150–200% of the weight and reduce gently; extract is already diluted.

  • Lime juice

    Use 60–70% of the weight with a pinch of jaggery; sharper, so add near the end off the heat.

Lime juice
  • Lemon juice

    Use equal volume or weight; slightly sweeter and less pungent, but otherwise an imperceptible swap.

  • Dried mango powder

    Use 25% of the weight; imparts dry, fruity sourness, best stirred in right at the end of cooking.

  • Tamarind extract

    Use 50% of the weight; delivers pleasant fruity tang but turns pale sauces considerably darker.

Ground black pepper
  • Black peppercorn

    Use 1:1 by weight; pulverise in a spice mill or mortar to a fine powder for immediate, punchy heat.

  • Coarsely ground black pepper

    Use equal weight; offers the same bite, though it gives a visibly speckled finish and firmer crunch.

Ground turmeric
  • Ground ginger

    Use 50% of the weight. Mimics turmeric's warm, earthy, rhizome background, but provides none of the golden-yellow colour.

  • Saffron

    Steep 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.

Kashmiri chilli powder
  • Dried kashmiri chilli

    Grind deseeded dried pods to an equal weight of powder; gives identical vivid red colour and gentle warmth.

  • Red chilli powder

    Use 25% of the weight mixed with sweet paprika for colour; straight red chilli powder is substantially hotter and will make the dish fiery.

  • Chilli powder

    Use one-third of the weight; the sauce will be less intensely red and notably sharper in heat.
