Apple, Leek, and Sweet Potato Gratin is an adaption of a French classic. The addition of apple and leeks add tremendous flavour. However, changing normal potato for sweet potato is a stroke of genius. The soft delicate flesh of the potato with the sweetness of the apple and leeks makes this a lovely side dish.
