4 cups all-purpose flour
1 3/4 cups vegetable shortening
1 TBSP sugar
2 tsp salt
1 TBSP vinegar
1/2 cup water
Mix flour, shortening, sugar, and salt with a pastry blender or your fingers. In a separate bowl, beat the vinegar, egg and water together. When the pastry crumbs are fine, gradually pour the liquid on top. Stir or toss the crumbs with a fork until all the ingredients are moist.
Form the dough into a ball. Chill in the refrigerator, covered, for at least 15 minutes before rolling out.
Divide into 5 balls. Roll each ball on a floured board or between sheets of waxed paper. Place in pie pans and crimp the edges. These freeze well if wrapped in plastic wrap.
To bake - place in a preheated 425 degree oven for 8 - 10 minutes until golden.
