Combine 1/4 cup oil with spices and rub all over lamb. Allow to marinate in self-sealing plastic bag in refrigerator overnight.
Korma Sauce
At least one day in advance, heat 1/2 cup vegetable oil in saucepan and sauté shallots and gingerroot. Reduce heat to medium.
Combine spices with shallots and ginger; mix well. Continue to cook about 10 to 12 minutes. Stir in water, coconut milk and raisin paste; heat and simmer for 15 minutes more. Turn into blender and purée. Cool.
Lamb
Preheat oven to 400°F. Drain lamb, discarding marinade. Heat remaining 1/4 cup oil in heavy pan and sear lamb. Transfer to oven and roast at 400°F for 15 minutes until medium (160°F).
To Serve:
When lamb is done, let stand for 10 to 15 minutes. Reheat sauce over low heat to slow bubble; finish with salt and lemon juice. Slice lamb and arrange on serving platter. Spoon Korma Sauce over all. Serve with Indian Buttered Rice (Nasi Biryani) and Malaysian Pickles (Achar).
Note:
Commercially prepared California raisin paste is available from foodservice and industrial suppliers. To make your own paste, grind or process in a food processor California raisins equal to twice the amount of paste (1 cup natural raisins) until very finely chopped and smooth.Nutrition Information (per serving)Calories 870(76% from fat); Total Fat 74g (sat 31g, mono 30g, poly 8g); Cholesterol 165mg; Protein 38g; Carbohydrates 16g; Fiber 2g; Iron 5mg; Sodium 1310mg; Calcium 62mg
