Vegetable shortening produces a flaky pie crust that is slightly easier to work with than one made with butter, but the flavor will nott be as rich.
In a large bowl with a pastry blender or two knives, cut vegetable shortening into flour and salt until particles are the size of small peas. Sprinkle in water, 1 tablespoon at a time, tossing with fork until all flour is moistened and pastry dough almost cleans side of bowl (1 to 2 teaspoons additional water can be added if necessary). You want the ingredients to barely bind together.
Pie dough benefits from a rest period after mixing. This will make the dough easier to roll and shape. Once the dough has come together, form it into a disc (approximately 1/2 inch thick) and wrap it tightly in plastic wrap. Place the prepared dough in the refrigerator during this resting time. As long as the dough is kept in the refrigerator, you can keep it there for as long as 24 hours. When ready to use, let the dough sit at room temperature approximately 20 to 30 minutes before rolling.
Flour your hands generously. Tilt the rolling pin and sprinkle it with flour as you rotate the rolling pin. On a lightly floured surface, form pastry into a ball; shape into a flattened round. (For two-crust pie, divide pastry into halves and shape into two rounds.)
Roll pastry 2 inches larger than an inverted pie plate with a floured rolling pin. Try to control the rolling pin and move from the center out. Do not use the rolling pin to go back and forth. Use your rolling pin something like this: Roll North, pick up the pin, roll Northeast, pick up dough and move counter-clockwise, repeat. You want the crust as evenly rolled as you can.
Fold pastry into quarter folds and ease into pie plate, pressing firmly against bottom and sides of pie plate.
