Wash the lamb and place in a 2-3 inch deep dish.
For marinade, combine remaining ingredients and mix well.
Pour over lamb being sure to cover thoroughly.
Cover and refrigerate for 1-2 days.
To cook, lightly barbecue and turn to low heat.
Place lamb on grill and cook 10-12 minutes each side, or until meat is cooked to your liking.
Pour remaining marinade over meat as it is cooking.
Lamb is typically served a bit on the rare side, but some like it more thoroughly done.
Serve with fresh cantaloupe and grapes paired with a green salad and steamed mini artichokes.
