ABSTRACT:
An illustrative embodiment of the invention comprises an annular device for preparing pie crusts in which the inner margin of the device defines the central, circular opening. The margin, perpendicular to the base of the device, also forms a cutting edge that slopes away from the opening and toward the base until it intersects a flat working surface for the device. An arcuate surface, curving from the working surface to the base enables the device to be positioned on a breadboard with the cutting edge oriented in the proper direction. By rolling dough deposited in the opening, the opening fills up to the margin and surplus dough flows over the cutting edge and onto the working surface, the cutting edge severing the surplus dough from the shaped mass in the opening. The device, with surplus dough, is lifted smartly away from the breadboard, leaving a circular pie crust of uniform thickness defined by the marginal distance between the base and the crest of the cutting edge.
