Method
- 1
Mix the goat with the yoghurt, half the ginger and garlic, the turmeric, chilli powder and salt. Leave for 30 minutes.
30 min - 2
Heat the mustard oil in a heavy pan until it just starts to smoke, then take it off the heat for 30 seconds. Add the dried chillies, cumin seeds, bay, cinnamon, cardamom and cloves and cook for 20 seconds. If you use rapeseed oil, just heat it until hot.
0 min 30 s - 3
Add the onions and sugar and cook over a medium heat for 20 minutes, stirring often, until a deep chestnut brown.
20 min - 4
Stir in the remaining ginger and garlic, the ground cumin and ground coriander for 1 minute. Add the goat and marinade and fry hard for 15 minutes, stirring, until the meat darkens and the oil separates. This frying is the kosha.
15 min - 5
Add the hot water, cover and simmer very gently for 1 hour.
60 min - 6
Add the potatoes, cover and cook for a further 40 minutes, until both meat and potato are tender. Lamb shoulder needs about 20 minutes less in total.
40 min - 7
Uncover and cook for 10 minutes until the sauce is thick and dark and clings to the meat. Stir in the ghee and garam masala and serve with plain rice.
