Slow cooker at about 225 if it's still partially frozen, add a splash of cooking wine, color doesn't really matter that much, or a splash of bourban even. It's precooked/smoked so you don't want to get too carried away with seasonings. Just a little hint, if it's on the bone, cook it till it pulls away from the ends of the bone, if it falls off the bone, its overcooked, and you lost all of the natural flavoring to the drippings.
