Hi The T - Keep it simple - brown the breast skin down for 3 mins in very hot fat in a baking tray then turn and 3 mins on the other side.
Place in hot oven and cook for no more than 5 mins then leave to rest while you make up the rest of the meal. Cherries are in season now and are good with duck, or as it quite a strong flavour anyway, it can take asian spices as well, or garlic as you suggest.
