Gratin

A gratin is the golden, epicurean crust that forms on the surface of savory baked or broiled dishes. Pungent Gruyère makes a genial topping that acts as a protective layer, preventing the potatoes from drying out.

Anne Macrae is a Scottish neighbor in Provence who shares my love of simple, big tastes. She served this luscious gratin one spring evening and explained that she devised the recipe when she and her husband, John, lived in an isolated part of northern Provence, in the Drôme. There were no fresh-produce markets nearby, but thanks to neighboring farmers she always had plenty of fresh goat's milk cheese—known as tomme. Her larder was always filled with the meaty black olives from nearby Nyons, and wild herbs were as near as the back door. In summer months Anne prepares the sizzling, fragrant first course with fresh tomatoes, and in the winter months she uses canned tomatoes. That evening she served the gratin in the individual gratin dishes, but I suggested it might be easier to make one huge gratin and pass it around. "I used to do that," she countered, "but people got greedy and never left enough for the other guests!" So controlled portions it is! This dish lends itself to endless variations: Think of it simply as a pizza without the crust. Add julienned bits of proscuitto, a bit of cooked sausage, sautéed mushrooms, or marinated artichokes. It's also a convenient dish when you're alone and want something warm and quick. I always add fresh hyssop, for the Provençal herb's pungent, mintlike flavor blends well with the tomato-cheese-olive trinity.

One of the great blue cheeses of the world, real English Stilton transforms potatoes au gratin into something extraordinary.
