1. Using a mortar and pestle, crush the garlic cloves, cumin seeds, sea salt, saffron, paprika, ginger, turmeric and cayenne, then add the butter to make a thick, creamy marinade. Rub the marinade into the lamb and refrigerate overnight.

2. Remove the lamb from the refrigerator 2 hours before cooking.

3. Preheat oven to 130˚C. Place lamb shoulders in a roasting tin large enough to fit both and drizzle with 2 tbsp olive oil. Add 125ml water. Fold the edges of two sheets of foil together to make a tent over the lamb, seal tightly then cook for 2½-3 hours.

4. Reduce the heat to 110˚C and cook for 4 hours more (if using a single large shoulder, keep oven at 130˚C for a similar cooking time). When the meat is ready, you will be able to tease it from the bone with a fork. Remove from the oven and allow to rest for 20 minutes, opening up the foil a fraction, then shred the meat off the bone.

5. Place meat on a platter, or divide among plates, and serve with lemon juice and extra virgin olive oil with the slivered almonds and parsley scattered over the top, as well as a really good grind of fresh pepper. Serve with orange and fennel salad.
