Julia Child’s Provençal Potato Gratin

Potatoes aren't usually associated with Provençal cooking, but every French region must have its gratin: sliced potatoes baked into a delicious mass that is the perfect side dish for roasts. The binder can be milk, broth, cream or, as in this case, the natural juices of vegetables like tomatoes and onions. With less liquid, this gratin is more foolproof than most. Anchovies give the dish a South of France funk, but you can leave them and the cheese out to make a vegan gratin.
