Chocolate Chess Pie

In a medium bowl, stir together the flour and salt. Using a pastry blender, cut in the shortening until pieces are pea-size. Sprinkle 1 tablespoon cold water over part of the mixture; gently toss with a fork. Push moistened dough to the side of the bowl. Sprinkle additional cold water, 1 tablespoon at a time, over mixture until all of the dough is moistened. Form the dough into a ball. On a lightly floured surface, flatten dough. Roll dough from center to edges into a 12-inch circle. To transfer pastry, wrap it around the rolling pin. Unroll pastry into a 9-inch pie plate. Ease pastry into pie plate, being careful not to stretch pastry. Trim pastry to 1/2 inch beyond edge of pie plate. Fold under extra pastry. Crimp edge as desired.
