One of the delights of summer in Germany is fruit kuchen, an open face fresh fruit pie served warm from the oven. It's made with pastry crust or raised yeast dough crust; a custard mixture is poured over the fruit before baking. In this recipe fresh ripe peaches is used, plus a crispy, rich biscuit crust, somewhat like shortcake. Kuchen can also be made with canned or frozen fruit. Fragrant peach kuchen is especially delicious with whipped cream or a la mode. Time the kuchen to bake during dinner so that it will be at just the right temperature to serve for dessert. The batter may be mixed ahead of time, turned into a baking pan and refrigerated for as long as 3 hours. At brunch, serve kuchen instead of coffeecake.
