For a 14-inch round pizza, on a lightly floured surface place 1 sheet of pastry on top of the other sheet, staggering corners. Roll pastry from center to edge, forming a 14-inch circle. (For a 15 x 10-inch rectangular pizza, place pastry sheets on top of each other without staggering the corners. Roll out pastry, forming a 15x10-inch rectangle.) Wrap pastry around the rolling pin. Unroll pastry into a 14-inch deep-dish pizza pan (or a 15 x10 x1-inch baking pan). Prick bottom well with the tines of a fork. Bake in a 375 degree F oven for 25 to 30 minutes or until pastry is golden brown. (Pastry may shrink).
