Let the dough soften slightly. On a floured work surface, roll out the dough to a round, about 1/8 inch thick. Roll the dough onto the rolling pin and unroll it over a 9-inch glass pie plate. Press the dough into the pie plate, being careful not to stretch it. Using scissors, trim the overhang to 1 1/2 inches. Fold the dough under itself and crimp decoratively. Refrigerate the pie shell until firm, at least 30 minutes.
