This dish comes from the Caribbean. The lamb is marinated in a spicy paste for 2 or 3 hours, then roasted with red peppers and black eyed peas. The result is that the beans soak up the meat's dripping and the peppers lend a touch of sweetness to balance this one-dish meal. Weigh your lamb for the exact cooking time. 20 minutes per pound yields a medium-cooked roast. Allow 5 minutes less/per pound for rare and 5 minutes more/per pound for well done.
