Grind together in an electric blender the coriander, cumin, poppy seeds, turmeric, garlic, ginger, cayenne pepper, green chili, coconut, paprika, cloves, cardamom, and one of the onions.
Heat vegetables oil and brown the remaining onion which has been thinly sliced.
Put in the cinnamon stick and the ground-spice paste. Fry for 3 minutes.
Add meat and fry for 5 minutes.
Put in salt and yogurt.
Cover and simmer slowly until meat is tender, adding just enough water to keep it from burning and to form a thick gravy.
