  3. Step 3: Place 4 smashed garlic cloves and 3 rosemary sprigs around the lamb in a roasting pan and add 1/2 cup water to the base.
  4. Step 4: Roast uncovered for 3 hours, basting every 45 minutes with pan juices to keep the meat moist and flavorful.

  6. Step 6: Increase oven temperature to 400°F (200°C) and roast for an additional 20 minutes until the glaze is sticky and caramelized.
