Fifteen-Minute Fruit Gratin

If you take soft, ripe fruit, top it with a fancy sauce like crème Anglaise, and run the whole thing under the broiler, you have a four-star dessert. But if you top the fruit with something like sweetened heavy cream, whipped just enough so that it holds some body when broiled, or sweetened sour cream—which hardly needs to be whisked—you can produce a similarly glorious dessert in less than half the time. Although this preparation is lightning-quick, it has to be constantly watched while cooking. Get the broiler hot, put the dish right under the heating element, and keep your eyes open. You want the topping to burn a little bit—it will smell like toasting marshmallows—but obviously not too much. When the topping is nearly uniformly brown, with a few black spots, it’s done. The fruit will not have cooked at all.
