Cut slits in the top of lamb, place in a roasting tray and pour marinade over the top. Massage well all over, including the slits, and pour a little stock into the tray. Cover with foil and cook in the oven for 30 mins. Then uncover and cook for about another 30-45 mins, to desired degree, basting now and again and adding a little more stock if needed.
