In a large bowl, combine flour and salt.

Add vegetable shortening; mix with pastry blender.

Add egg, vinegar and water; work with pastry blender until mixture resembles small peas. (don't be afraid to mix well and handle. If it falls on the floor, pick it up and go on: you can't hurt this recipe. The germs cook out.)

Roll on a floured board to make pie crusts or many, many tarts.

Freezes well If covered with foil.

Bake as usual for pie crust
