Combine flour, sugar and salt in Classic Batter Bowl. Cut shortening into flour mixture using Pastry Blender until shortening resembles size of large peas. Combine egg and vinegar in small bowl; stir into flour mixture, mixing slightly. Add water, 1 tablespoon at a time, mixing just until dough is moist enough to form a ball. Shape dough into 2 balls. Flatten 1 ball to 1/2-inch thickness, rounding and smoothing edges.
Divide dough into 2 portions; shape each portion into a ball. Flatten 1 ball to a 1/2-inch-thick circle, rounding and smoothing edges. On lightly floured surface, roll dough into a 11-inch circle. Slide Large Spreader under dough to loosen. Lightly fold pastry in half; place in pie plate. Gently unfold dough, easing into pie plate; press onto bottom and sides of pie plate. Trim dough to 1/2-inch beyond edge of pie plate.
Roll out remaining dough for top crust, if double-crust pie is being prepared, or roll out as directed above for another single-crust pie shell. Fill pie shell as recipe directs. Place top crust over bottom crust; seal and trim edges evenly. Crimp or flute edges as desired. Cut several slits in top crust to allow steam to escape. Bake as directed.
