In a pressure cooker, heat up the ghee.
Add all the spices and fry until the mustard and cumin seeds pop.
Add the onion, garlic and ginger and fry till the onions have turned yellow.
Add the goat pieces.
Add enough water to just cover half the height of the goat pieces.
Cover the pressure cooker and cook for 20 minutes if goat is at room temperature. I cooked from frozen, so it took 45 minutes.
Adjust seasoning and heat with chilli powder.
Separate the goat pieces from the curry, and grind the curry into a smooth psate.
Serve with nasi bryani, pilaf, french loaves and plain rice. Better eaten the next day.
