2 cups onions, chopped
3 garlic cloves, chopped
2 teaspoons ginger root, chopped
1/2 cup cold water
1/2 teaspoon cayenne pepper

Total time: 1 hrs 45 mins

1.In a large bowl, combine saffron and boiling water; soak for 10 minutes. Add yogurt, caraway seed, and salt. Add diced lamb and toss to coat evenly. Marinate at room temperature for about 30 minutes.
2.Combine almonds and boiling water in a bowl, and soak for 10 minutes. Pour the almonds and the soaking water into a blender and blend to a smooth paste; set aside.
3.In a heavy skillet, heat butter until hot. Add cinnamon stick, cardamom, and whole cloves. Stir for 1 minute. Saute chopped onions, chopped garlic cloves, and chopped ginger root. Cook, stirring constantly, for 7 to 8 minutes, or until the onions are soft and golden brown. Remove the lamb from the marinade and add to the skillet. Cook over moderate heat until evenly browned. Stir in the marinade and cold water, then add the almond puree and cayenne pepper. Cook for 10 minutes, stirring occasionally. Pour in coconut milk, bring to a boil, reduce the heat, and simmer for 20 minutes, or until the lamb is tender. Discard the cinnamon stick and cloves.
