Marmalade-glazed lamb recipe

1. Mix 2 tbsp marmalade, 2 tsp sumac, the garlic, zest and juice of 1 clementine and 2 tbsp oil. Put the lamb in a snug-fitting, hob-safe roasting tin and lightly score the fat side in a criss-cross pattern. Rub the spiced marmalade all over the lamb. Cover and chill in the fridge for at least 1 hr (or at room temperature if cooking immediately), or for up to 24 hrs to marinate. 
2. Bring the lamb up to room temperature at least an hour before cooking. Preheat the oven to gas 3, 170°C, fan 150°C. 
3. Lift the lamb out of the tin and arrange the onions cut-side down underneath. Put the lamb on top and season all over. Pour the stock around the lamb and cover tightly with a double layer of foil. 
4. Roast for 4 hrs 30 mins, basting in the juices every 2 hrs, until the meat pulls away with a fork. 
5. Increase the oven temperature to gas 6, 200°C, fan 180°C; remove the foil. Baste the meat with the cooking juices, then brush with the final 1 tbsp marmalade; return to the oven for 15 mins. 
6. Transfer the lamb and onions to a board to rest for 20 mins. Skim away any fat from the tin with a spoon and discard. Put the tin with the juices in it over a low heat to keep warm. 
7. Shred the meat and serve with the onions and warm roasting juices. Sprinkle with the mint, extra sumac and remaining clementine zest to serve.
