Recipe: Sweet Potato Gratin

SWEET POTATO GRATIN

Potato gratin is a classic french dish and there are so many versions. Dauphinoise is perhaps the most popular and this recipe is SORTED's twist on that. Made with layers of sweet potato and white potato and finished with an infused cream it's baked and served with marinated and pan-roasted pork fillet and savoy cabbage. A surprisingly cheap family dish that oozes flavour...
