Spice blend for 1 kilo of lamb cubes:
2 tblsp fennel seeds
Seeds from 1 tblsp green cardamom pods
1 tsp cloves
1 (real) cinnamon stick
1 bay leaf
Dry roast all of the above for a minute or two until lightly toasted. Then grind to a powder.
Mix the powder well with the lamb and 4 cm grated ginger, five cloves garlic finely crushed, and 100 g full-fat yoghurt. Marinate for at least half an hour.
Blend 100 g cashew nuts to a paste with 1 tblsp boiling water.
Heat 100 g ghee over medium heat and soften (do not brown) one medium-sized onion, coarsely chopped. Add the meat with all the marinade and enough water to almost cover the meat.
Cook for 45 minutes to an hour. Add a heaped tsp salt and 1 tsp ground seeds from green cardamom pods.
Add the cashew nut paste and 50 ml double cream. Add water if needed. Heat through before serving.
