  3. For marinade, in a 12 inches 8 inches baking dish, combine peppercorns and the next 5 ingredients. Add butterflied lamb turn upon to coat evenly. Cover with plastic wrap; refrigerate for at least 12 hours, turning meat occasionally.
  4. About 45 minutes before serving: Preheat broiler if manufacturer directs. Drain lamb, reserving marinade. Place lamb on rack in the broiling pan. Broil about 5 inches from the source of heat (or at 450° F.) for 10 minutes, occasionally basting with marinade. Turn and broil 15 minutes longer for rare or until meat is of the desired doneness. Place on carving board; garnish lamb with sprigs of parsley.

Butterflying a Lamb Leg Shank Half

Place lamb, fat side down on cutting board. With a boning knife, cut through meat parallel to the bone to expose the main leg bone. Keeping the knife blade against the bone, scrape all meat from around the body until you reach the knee connected.

Turn the leg slightly and cut around the knee joint. Continue to cut meat from the knee down to the second leg bone. Remove leg bone. Since the boned lamb has an uneven thickness, cut the thicker muscles almost in half and open like a butterfly to make it flatter for a more even thickness. It will have an irregular shape. Trim excess fat from meat.
