Did a 10+ pound leg of lamb a few years ago. Started off by cleaning up the loose skin and fat that didn't look right. Made up a mixture of melted butter, olive oil, fresh rosemary, fresh lemon juice, tons of garlic slivers, salt and pepper. I took a knife and stabbed the leg a few dozen times. into those stabs I put the garlic/rosemary mixture in as far as I could. Cooked over an open charcoal pit with a hand-cranked rotisserie. Brushed with remaining mixture throughout the cook. Can't remember how long it took but the final temp was at 135-145. The aroma brought out neighbor's I hadn't seen before. This is a slicing temperature and not for pulling. The flavor can be a little bit strong for some. But damn it made some great ass sandwiches.
