Simple Pastry

Directions

1. 1
   In a food processor (or in a large bowl, using a pastry blender, 2 crossed knives, or your fingertips), combine the flour, salt, butter, and shortening until the mixture is crumbly and the size of peas. Break the egg into a measuring cup and beat lightly; add the vinegar and enough cold water to measure 1/2 cup. Slowly add the egg mixture to the flour mixture and stir until a soft dough forms. Divide in half. Shape each half into a flat disk and wrap in plastic. Refrigerate for at least 1 hour.
2. 2
   The vinegar makes the pie dough especially tender and workable, allowing you to wrap the disks of dough in resealable plastic bags and freeze them for up to 3 months. Thaw partially before rolling them out.
