Preparation / Directions:
Place all ingredients (except the roast) in a blender and blend.
Pierce roast on all sides and place in a zip-lock with the marinade. Chill, turning frequently about 12 hours.
Grill one and one half hours, covered. Start roast on a hot grill, about 15 minutes, to char outside; turn heat to low.
Baste frequently with marinade. Remove from heat, allow to rest 10 minutes, slice and serve.
If you have fresh rosemary throw a couple sprigs on the coals as you grill...smells wonderful.
