Combine buttermilk and World Rub to form a marinade for the lamb. For the best result,
marinate overnight. Otherwise, marinade the meat for at least 3-4 hours.
Brush the kettle grill with oil. Cook the lamb over medium coals for 30-40 minutes depending on your preference. Remove and set aside for 5-10 minutes. Slice and serve with a green salad of your choice or Corn Salsa (page 100).
