Pastry-dough circles or squares that are covered with a sweet or savory filling, then folded in half to create a pastry in the shape of a triangle or semicircle. The edges are usually pinched or crimped to prevent the filling from leaking. Turnovers may be baked or deep-fried. They can range from bite-size to about 6 inches across and can be served as appetizers, luncheon entrées or desserts.
