Instructions

  1. Step 1: Preheat oven to 325°F. Score the fat on a 3 lb bone-in lamb shoulder in a crisscross pattern. Insert 6 sliced garlic cloves and 4 sprigs of fresh rosemary into the cuts.
  2. Step 2: Rub the lamb shoulder all over with 3 tbsp olive oil, then season generously with 2 tsp sea salt, 1 tsp black pepper, and 1 tbsp crushed native pepperberry.
  3. Step 3: Place the lamb in a roasting pan and pour 1 cup dry white wine and 1 cup water into the pan to keep the meat moist during cooking.
  4. Step 4: Cover the pan tightly with foil and roast in the oven for 3.5 to 4 hours, basting every hour with pan juices, until the lamb is fork-tender and falling off the bone.
  5. Step 5: Remove foil and roast uncovered for an additional 15 minutes to crisp the exterior. Let rest for 15 minutes before slicing and serving.
