Ingredients

Instructions

  1. Step 1: Preheat oven to 275°F (135°C). Rub 3 lbs lamb shoulder all over with 3 tbsp olive oil, 2 tsp salt, 1 tsp black pepper, 5 crushed garlic cloves, and 4 fresh rosemary sprigs, pressing the herbs and garlic into the meat.
  2. Step 2: Place the lamb in a roasting pan, cover tightly with foil, and slow-roast for 3.5 to 4 hours until the meat is tender and easily pulls apart.
  3. Step 3: Meanwhile, in a small bowl, whisk together 2 tbsp finger lime pulp, 1 tbsp honey, and 1 tbsp red wine vinegar to make the glaze.
  4. Step 4: Remove the lamb from the oven, increase oven temperature to 425°F (220°C), brush the finger lime glaze over the lamb, and roast uncovered for 10-15 minutes until caramelized and sticky. Rest for 15 minutes before carving.
