Achari gosht is a slow-cooked lamb curry with a thick, clinging gravy and pickling-style spices. It tastes tangy, savoury and warmly hot, with tender lamb and a rich sauce.
Turmeric for the lamb boil
3 gStirred into the lamb and water at the start (step 1)
Put 850 g lamb shoulder on the bone, 0.3 g salt, 3 g ground turmeric and 596 g water into a heavy-based saucepan. Heat over medium-high until boiling, then cover, lower to a gentle simmer and cook for 30 minutes. Switch off and let cool slightly.
Lift the lamb out with a slotted spoon into a bowl. Keep the lamb and the cooking stock separately.
Blend 18 g garlic, 5 g ginger root and 3 tbsp water to a smooth paste. Set aside.
Crush 3.5 g black mustard seed, 2 g fennel seed and 2.1 g cumin seed coarsely in a pestle and mortar. Set aside.
Heat 54 g vegetable oil in a large heavy non-stick saucepan over medium heat. Add 250 g white onion, thinly sliced, and fry for 17–18 minutes, stirring and scraping any browned bits from the pan, until beginning to brown.
Add the dried chillies for the onion pan (6 g dried kashmiri chilli) and fry for 2 minutes.
Add the whole spices for the onion pan (1.9 g black cardamom pod, 0.4 g clove and the reserved crushed seed mix) and stir-fry for 1 minute.
Stir in the garlic and ginger paste and fry for 10 seconds until the raw smell goes.
Mix the ground achari spices for the sauce (1.4 g asafoetida, 5.6 g mango powder and 3.9 g kashmiri chilli powder) with 2 tbsp reserved lamb stock in a bowl. Stir this slurry into the pan.
Add the reserved lamb pieces and season with extra salt to taste. Mix and fry for 2–3 minutes.
Pour in 450 g of the reserved lamb stock and add 13.5 g dark brown sugar. Stir well, cover and simmer over low heat for 50 minutes, stirring twice so it does not catch. Add a little more stock only if the gravy looks too dry; aim for a thick gravy.
Scatter chopped coriander to taste over the curry before serving.
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.
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.
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 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 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.
