Hi Kevin
What i do is heat some oil in a saucepan with 2 bay leaves, 1 star anise, 2 inches cassia bark (or cinnemon) half a dozen cracked green cardamums, some salt, 1tsp ginger paste, 1 tsp garlic paste 1 tsp turmeric, 1 tsp corriander powder and 1 tsp garam massala.
When everythings sizzling well; add the lamb and keep stirring until the meat is browned off. Then add enough boiling water to just cover the meat, turn the heat right down and simmer for an hour with the lid on. If its still a bit tough (doubtful) leave it to simmer for a bit longer. Its not my recipe - I got it off this site but cant remember where. I think its one of CK's. It has never failed me (yet)
Regards
Mick
