Ingredients

1/4 Cup white vinegar
1 Can beer
1/4 Cup olive oil
4 large cloves garlic, chopped
2 bay leaves
1 Tablespoon crushed rosemary
1 Teaspoon oregano
1/4 Cup mint leaves, chopped
1 Tablespoon coarse ground black pepper
1 5-6 pound leg of lamb, bone in or butterflied

Instructions

Mix together vinegar, beer, olive oil, garlic and bay leaves. Lay lamb in large shallow glass baking dish. Reserve a small amount of marinade for basting and pour remaining marinade over the lamb. Mix together the remaining spices. Sprinkle a generous amount on the lamb and rub into the meat, reserving some of the mixture for later. Cover and refrigerate for 6 to 8 hours. Turn meat occasionally and rub in remaining spice mixture. (Add another can of beer or water to the marinade for more volume, if desired.) Grill lamb on low on a gas grill or with indirect heat method using charcoal. Place lamb on grill (fat-side-up) and cook for about 40 minutes, basting frequently with reserved marinade and turning at least once. Check for doneness using a meat thermometer after 30 minutes of cooking. Continue checking every few minutes. Do not overcook; medium-rare to medium is best for tenderness and juiciness. Carve into thin slices, cutting against the grain. Serve immediately with mint jelly or relish.
