A combination of North African spices give this braised, boneless lamb a subtle exotic flavour. Serve with pine nut and parsley rice for an alternative to your usual roast on Sunday. And there will be plenty leftover to make a mild lentil and lamb curry, a creamy herb dish with rice or a main course soup.
Preheat the oven to gas 3, 170°C, fan 150°C. Using a sharp knife, make several 2.5cm (1in) deep cuts in the lamb. Place a large flameproof casserole dish over a medium to high heat and add the oil. Brown the lamb on all sides to seal. Remove from the pan and set aside. Add the onion, celery, leek and carrots to the casserole dish and cook for 5 minutes until soft.
Season well and stir through the harrisa, coriander and cinnamon and cook for 2 minutes. Stir in the chopped tomatoes and return the lamb to the pan. Cover the lamb with a tight-fitting lid and transfer to the oven to cook for 2 hours. Then remove the lid, stir the stock into the vegetables and return to the oven, uncovered, for 30 minutes. Place the rice in a medium pan with 500ml (17fl oz) water. Bring up to the boil and simmer for 10-15 minutes until all the water has been absorbed.
Remove from the heat, cover and set aside until needed. Toast the nuts in a small, heavy-based pan, over a medium heat for 2‑3 minutes, until fragrant, moving them around in the pan often. Roughly chop the nuts and stir them through the rice with half the parsley. When the lamb is cooked, remove it from the casserole with a slotted spoon and cut into slices.
Stir the remaining parsley through the vegetable mix. Serve the sliced lamb with the rice, vegetables and sauce and a spoonful of natural yogurt. Set aside the leftover meat until cool. Wrap in foil or place in a lidded airtight plastic box and store in the fridge. Use within 2 days.
Remove the bone from the leg of lamb, then to butterfly, place the lamb, skin side down on a board, slice through the meat holding the knife parallel to the board to give you a flap of meat which you can open out like a book. Repeat on the other side, the idea is to produce a flattish piece of meat roughly the same thickness throughout.
