Slow-Cooked Lamb and Potato Curry with Fennel Seeds, Mustard Oil and Garam Masala
Non-vegetarianOrigin East
A slow-cooked Bengali lamb curry with potatoes, fennel and garam masala, enriched with mustard oil and yoghurt. It is gently spicy, aromatic and rich, with tender lamb and soft potatoes.
Marinade chilli
1.3 gStirred into the yoghurt and mustard oil marinade (step 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.
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.
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.
Heat 26.4 g ghee in a large saucepan over medium heat.
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.
Stir the asafoetida from the same masala (2.8 g) and 4.2 g granulated sugar into the ghee.
Add the ginger-chilli paste and fry for 1 minute.
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.
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.
Add 250 g potato, peeled and cut into large chunks. Cover and cook for 25 minutes until soft.
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.
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.
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.
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.
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.
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.
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.
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.
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.
