Method

  1. Mix 45 g greek yoghurt, 4.5 g mustard oil and the marinade chilli (1.3 g kashmiri chilli powder) in a large bowl. Add 700 g bone-in lamb leg pieces and turn until coated. Cover and chill for 1 hour, or overnight.
  2. Blend 10 g fresh ginger root and 2 g green bird’s eye chilli with a splash of the 348 g water to a smooth paste.
  3. Grind 0.5 g cinnamon stick, 1.1 g green cardamom pod and 0.1 g clove to a fine powder, then mix with 0.6 g ground nutmeg.
  4. Heat 26.4 g ghee in a large saucepan over medium heat.
  5. Add the whole spices for the ghee: 3 g dried kashmiri chilli, 0.4 g dried bay leaf, 0.9 g green cardamom pod and 1.3 g cinnamon stick. Cook until they sizzle.
  6. Stir the asafoetida from the same masala (2.8 g) and 4.2 g granulated sugar into the ghee.
  7. Add the ginger-chilli paste and fry for 1 minute.
  8. Add the marinated lamb with its yoghurt and the ground spices for the lamb: 1.3 g kashmiri chilli powder, 0.8 g ground turmeric, 14.4 g coriander-cumin powder and 2 g fennel seed. Fry for 10–12 minutes, turning, until the lamb is sealed.
  9. Pour in the rest of the 348 g water and add salt to taste. Cover and simmer over low heat for 50 minutes, stirring once halfway.
  10. Add 250 g potato, peeled and cut into large chunks. Cover and cook for 25 minutes until soft.
  11. Lightly crush some of the potatoes against the side of the pan. Stir in the finishing spices and 10 g mild green chilli, slit lengthways.

Don't have something?

Leg of lamb
  • Leg of spring lamb

    Use the same weight; younger and tenderer, so reduce cooking by 10–15 minutes.

  • Lamb shoulder

    Use the same weight; more fat, so cook 15–20 minutes longer and skim excess fat.

  • Leg of goat

    Use the same weight; stronger flavour and tougher, so cook 15–20 minutes longer.

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.

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.

Ghee
  • Unsalted butter

    Use 120% of the weight; melt gently over low heat to avoid burning the milk solids, which will yield a softer, creamier richness rather than a nutty aroma.

  • Vegetable oil

    Use 85% of the weight; holds high cooking temperatures without smoking, but the final dish will lack traditional dairy depth.

  • Mustard oil

    Use equal weight; heat to smoking point and cool slightly before cooking, bearing in mind it introduces an assertive, pungent edge.

Dried kashmiri chilli
  • Kashmiri chilli powder

    Use 1 g powder for every 1.5 g whole dried chilli; whisk with a spoonful of warm water and stir into the masala to provide identical ruby colour and mild heat.

  • Dried red chilli

    Use 35% to 40% of the weight; discard seeds before tearing into oil to temper. Delivers a much fiercer heat, with significantly less red colouring.

Bay leaf
  • Cinnamon stick

    Use a 2 cm piece (about 1 g) for every 1 to 2 bay leaves. Fry in whole-spice temperings; provides the cassia-like warmth typical of Indian tejpatta.

  • Ground cinnamon (cassia)

    Use 0.5 g per leaf. Stir into the sauce during simmering; gives the same warm woodiness but darkens the colour slightly.

Green cardamom pod
  • Green cardamom seed

    Use 35 to 40% of the total pod weight; lightly bruise the seeds before frying in oil to release their essential oils.

  • Ground green cardamom

    Use 20 to 25% of the pod weight (about 1 generous pinch per pod); stir in toward the end of cooking so the delicate floral notes do not dissipate.

  • White cardamom pod

    Use 1:1 by pod count or weight; crack gently before using, though it is slightly less intensely floral.

Cassia bark
  • Ceylon cinnamon

    True cinnamon: thinner, papery quills, milder and sweeter. Use about 1.5 times the weight, and taste.

  • Ground cinnamon (cassia)

    Use about a third of the weight (0.5 g ground for a 2.5 cm piece), stirred in with the ground spices rather than fried whole, since the powder burns quickly.

  • Cassia buds

    Use 60-70% of the weight; stronger and more peppery, so taste before adding more.

Asafoetida
  • Garlic powder

    Use double the weight. Stir into hot oil just before adding wet ingredients; mimics the allium savoury background without the sulphurous edge.

  • Garlic paste

    Use 2 g for every 0.5 g of asafoetida. Sauté in oil until the raw smell clears; adds moisture and sweet allium depth.

Granulated sugar
  • Jaggery

    Use equal weight; grate or shave finely so it dissolves rapidly, giving a warm, caramel-like sweetness and slightly darker sauce.

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.

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.

Coriander-cumin powder
  • Ground coriander

    Use the same weight and add ground cumin at half the weight if you have it; without cumin it is flatter.

  • Ground cumin

    Use only one-third of the weight and top up with ground coriander; cumin alone is too strong.

  • Coriander seeds

    Grind to powder and use the same weight; add a pinch of ground cumin. Toast first for more aroma.

Fennel seed
  • Aniseed

    Use 75% of the weight. Fry in hot oil or ghee; has a sharper, more pronounced liquorice flavour, so use a lighter hand.

  • Ground fennel seed

    Use 60% of the weight. Stir into the sauce with ground masalas; provides identical sweet aniseed flavour without whole seed crunch.

  • Star anise

    Use one point (single carpel) per 1 g of fennel seeds. Simmer in gravies and remove before serving; gives a deeper, woodier liquorice aroma.

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.

Potato
  • Eggplant

    Use equal weight. Cut into large chunks; cooks down much faster (10-12 minutes) and softens into the sauce rather than staying starchy and firm.

  • Paneer

    Use 80% of the weight. Cube and add in the last 5-10 minutes of cooking; adds rich dairy protein instead of starchy bulk.

  • Dried chickpea

    Use 45% dry weight. Soak overnight and boil until fully soft before stirring into the sauce to simmer for 10 minutes.

Ground nutmeg
  • Nutmeg

    Grate whole nutmeg finely on a microplane; use 80% to 100% of the weight. Freshly grated nutmeg has significantly more aromatic oils and a more vibrant aroma.

  • Ground mace

    Use 100% to 120% of the weight. Mace is nutmeg's outer husk, providing almost identical warmth but with a lighter, slightly more delicate, floral edge.

  • Ground cinnamon (cassia)

    Use 75% of the weight. Adds comparable warmth and sweetness, though it lacks the musky, nutty undertone of nutmeg.

Mild green chilli
  • Mild chilli

    Use the same weight; deseed if you want less heat. Chop as required.

  • Jalapeño chilli

    Use the same weight; deseed for mildness. It is slightly firmer, so cook a minute longer.

  • Green bell pepper

    Use twice the weight for bulk with no heat; chop small and cook a little longer.

Greek yoghurt
Mustard oil
  • Peanut oil

    Use equal weight. It handles high-heat cooking well, but lacks the signature pungent, nasal heat of mustard oil.

  • Vegetable oil

    Use equal weight. Neutral in flavour, so your curry will lack the characteristic Bengali or North Indian pungent punch.

Clove
  • Ground cloves

    Use 1 g ground for 4 g whole (or 1 small pinch per 2 to 3 whole cloves). Add with spice powders; disperses intense warmth quickly, so use with restraint.

  • Allspice berries

    Use 100% of the weight whole in tempering. Imparts a warm, clove-like aromatic profile combined with hints of nutmeg and cinnamon.

  • Black cardamom pod

    Use 1 pod for 3 to 4 cloves in whole tempering. Shares a camphor-like warmth and medicinal depth, though it introduces a distinct smoky undertone.
