Trim lamb leg of nearly all
visible fat and leave to stand in a marinade made from the next five ingredients, in an
unpunctured plastic bag for at least an hour, but overnight if possible. Remove from
marinade, lie leg on sprigs of rosemary and roast uncovered at 160-180C (325-350F) for 1
½ - 2 hours, or for the time you like a leg cooked, basting occasionally with the
marinade.
After cooking leave to stand in a warm place for ¼ hour
before carving. Serve with Roasted Garlic Purée and a selection of roast or just cooked
seasonal vegetables.
