Make this stunning lamb bhuna a day or two ahead of a big family feast – slow-cooked curries are better when the flavours have time to develop
Prep:30 mins
Serves 4
600g lamb neck fillet or shoulder, cut into large chunks
STEP 1To make the marinade, combine the ingredients with a large pinch of salt in a large bowl. Toss in the lamb, cover and marinate for 1 hr at room temperature, or chill overnight.STEP 2For the sauce, heat the oil in a flameproof casserole and fry the onions for 10 mins, stirring until soft and golden. Drizzle in more oil if the pan gets dry. Add the curry leaves and chillies and fry for a few minutes, then add the spices and cook for 5 mins more until the onions start to caramelise.STEP 3Tip in the lamb along with the marinade and turn the heat to high. Cook, stirring, for 5 mins until the lamb browns. Add the tomato purée and cook for 1 min, then stir in the tomatoes and 100ml water. Bring to a simmer, reduce the heat, cover and cook, stirring now and then, for 1 hr 20 mins until the lamb is tender.STEP 4Uncover and cook for 8-10 mins more until the sauce has reduced and thickened. Remove from the heat, stir in the garam marsala and season. Will keep chilled for up to three days or frozen for two months.
