- two 7- to 8-pound legs of lamb, trimmed of excess fat, boned, and butterflied by butcher (each 4 to 4 3/4 pounds boneless)
- 1 cup fresh lemon juice
- 12 garlic cloves, chopped fine
- 1/4 cup chopped fresh thyme leaves
- 1/4 cup chopped fresh oregano leaves
- 1/2 cup chopped fresh rosemary leaves
- 3 tablespoons coarse salt
- 1 cup olive oil
- freshly ground black pepper to taste
- Garnish: fresh herb sprigs
- Accompaniment:coriander chutney
- Put each leg of lamb into a large sealable plastic bag, folding meat if necessary.
- In a bowl whisk together remaining ingredients and divide between bags. Seal bags, pressing out excess air, and stack in a shallow baking pan. Marinate lamb, chilled, turning it once or twice, at least 8 hours and up to 1 day.
- Prepare grill.
- Remove lamb from bags, discarding marinade, and grill on an oiled rack set 5 to 6 inches over glowing coals 8 to 12 minutes on each side (medium-rare for thin parts of meat and rare for thicker parts). (Alternatively, lamb may be broiled 3 to 4 inches from heat.) Cool lamb to room temperature. Lamb may be cooked 1 day ahead and chilled, wrapped well. Slice lamb thin and arrange on a platter. Bring lamb to cool room temperature, its surface covered with plastic wrap.
- Garnish lamb with herb sprigs and serve with chutney.
