It looks like a pizza, it cooks like a pizza, but don't make the mistake of actually thinking it's a pizza. Tarte flambée, the Alsatian flatbread topped with fromage blanc (a fresh, tart, spreadable cheese), thinly sliced raw onions and bacon, is as Franco-Germanic in flavor as can be. This method delivers a classic tart, made on pizza dough rolled very thinly and cooked on a blazing hot Baking Steel or pizza stone right under the broiler.
