Instructions

  1. Step 1: Preheat oven to 300°F. Rub 4 lbs lamb shoulder all over with 3 tbsp olive oil, 1 1/2 tsp sea salt, 1 tsp black pepper, 5 minced garlic cloves, and 2 tbsp chopped fresh rosemary.
  2. Step 2: Place lamb in a roasting pan and roast uncovered for 3 hours, basting occasionally with pan juices to keep moist.
  3. Step 3: While lamb roasts, soak 1/2 cup dried bush tomatoes in 1/2 cup warm water for 20 minutes, then puree with 3 tbsp tomato paste, 2 tbsp brown sugar, 1 tsp pepperberry powder, and 1/4 cup red wine vinegar until smooth.
  4. Step 4: During the last 30 minutes of roasting, brush the bush tomato glaze generously over the lamb every 10 minutes, allowing it to caramelize and form a sticky crust.
  5. Step 5: Remove lamb from oven when tender and falling apart. Rest for 15 minutes before slicing and serving with roasted root vegetables or creamy mashed potatoes.
