Ingredients:
 
Makes two 9 inch pie crusts, two 9 1/2-inch or 10-inch tart crusts, or one 9 inch covered pie crust

"This dough makes a light, flaky crust that shatters at the touch of a fork. If you need only a single pie or tart crust, decrease all ingredients by half or freeze half the dough for future use."

2 1/2 cups all-purpose flour
1 teaspoon white sugar or 1 tablespoon powdered sugar
1 teaspoon salt
1 cup solid vegetable shortening, or 1/2 cup shortening and 8 tablespoons (1 stick) cold unsalted butter
1/3 cup plus 1 to 3 tablespoon ice water, divided

Directions:

Using a rubber spatula, thoroughly mix flour, sugar, and salt in a large bowl.

Break the shortening into large chunks; if using butter, cut it into small pieces, then add it to the flour mixture. Cut the fat into the dry ingredients by chopping vigorously with a pastry blender or by cutting in opposite directions with 2 knives, one held in each hand. As you work, periodically stir dry flour up from the bottom of the bowl and scrape clinging fat off the pastry blender or knives. When you are through, some of the fat should remain in pea-sized pieces; the rest should be reduced to the consistency of coarse crumbs or cornmeal. The mixture should seem dry and powdery and not pasty or greasy.

Drizzle 1/3 cup plus 1 tablespoon ice water over the flour and fat mixture. Using the rubber spatula, cut with the blade side until the mixture looks evenly moistened and begins to form small balls. Press down on the dough with the flat side of the spatula. If the balls of dough stick together, you have added enough water; if they do not, drizzle 1 to 2 tablespoons ice water over the top. Cut in the water, again using the blade of the spatula, then press with your hands until the dough coheres. The dough should look rough, not smooth.

Divide the dough in half, press each half into a round fiat disk, and wrap tightly in plastic. Refrigerate for at least 30 minutes, and preferably for several hours, or for up to 2 days before rolling. The dough can also be wrapped airtight and frozen for up to 6 months; thaw completely before rolling.
