Vol-au-vent
A vol-au-vent is a small hollow case of puff pastry. It was formerly also called a patty case. A vol-au-vent is typically made by cutting two circles in rolled out puff pastry, cutting a hole in one of them, then stacking the ring-shaped piece on top of the disc-shaped piece. The pastry is cooked, then filled with any of a variety of savory or sweet fillings.
