Instructions

  1. Step 1: Preheat the oven to 275°F (135°C). In a small bowl, mix 4 tbsp olive oil with 3 tbsp chopped fresh rosemary, 6 minced garlic cloves, 2 tbsp ground wattleseed, 2 tsp salt, and 1 tsp black pepper.
  2. Step 2: Rub this herb and spice mixture all over the 4 lb bone-in lamb shoulder, ensuring even coverage.
  3. Step 3: Place the lamb in a roasting pan and pour 1 cup dry white wine and 1 cup beef or lamb stock around it.
  4. Step 4: Cover the roasting pan tightly with foil and slow-roast in the oven for 4 to 4.5 hours until the lamb is tender and pulls apart easily with a fork.
  5. Step 5: Remove the foil, increase oven temperature to 425°F (220°C), and roast uncovered for an additional 15 minutes to crisp the exterior.
  6. Step 6: Let rest for 15 minutes before slicing or pulling the lamb for serving with pan juices.
