I am firmly of the belief that a good pie crust improves just about any dish, be it savory or sweet. Flaky, crisp, and butter-rich, such a crust can transform many a ho-hum pile of fruit or bowl of stew into exciting new fare. Take the Vol-au-Vent from Yvette van Boven's Home Made Winter, for example. A simple stew of root vegetables, mushrooms, and crème fraîche is good enough on its own; but place it inside a buttery pastry shell, and it turns into an elegant vegetarian main dish. Brightened up with a smidgen of red onion compote, and you'll have a real winter winner on your hands.
