Trim the lamb, if necessary, and rub both sides of the rack with olive oil. Sprinkle with rosemary and pepper, rubbing them into the meatiest parts of the racks. Prepare a charcoal or gas grill. Lightly spray the grill rack with vegetable oil cooking spray. The coals should be moderately hot to hot. Grill the racks, meat side down, for 4 or 5 minutes, or until the temperature of the meatiest part reaches 100Â°F. Move the racks to the edge of the grill, away from the hottest part of the fire, and cook, covered, for 15 to 20 minutes longer, or until the temperature reaches 140Â°F for rare meat.
Rack of lamb should be cooked rare, or at most medium rare. The instructions are for a rack 1 1/4 to 2 pounds big. If you are cooking multiple racks (unless you are doing a crown roast which is a different matter), lay them out separately on the pan, and you may need to increase the cooking time. Preheat oven to 450Â°F, arrange the oven rack so that the lamb will be in the middle of the oven. Score the fat, by making sharp shallow cuts through the fat, spaced about an inch apart. Sprinkle the rack all over with salt and pepper. Place the lamb rack bone side down (fat side up) on the pan.
