(This is fine for mutton and can also be used cooked as a sauce for hamburger patties and for making a leg of lamb in a casserole in the oven)
Mix all ingredients and use as marinade. If used for sauce over patties, please cook till onions are done, or else you can saute the onions and garlic before putting it into the marinade, and only heat up the sauce before serving it with the burgers. If used for marinade, put meat overnight in it and remove just before barbequing it over hot coals. Baste frequently while roasting it over coals. If used to make a leg of lamb in the oven, put the leg of lamb in it and bake in sauce till tender and done. Serve this with maize bread and a green salad.
