Mix gluten free flour, salt and sugar in a bowl. Cut in shortening with a pastry blender or 2 knives (I use my fingers). Add egg, vinegar and 3 tablespoons water. Mix lightly. If dough is too dry, add more water. Mix with hands. Don’t over mix. Mix just until the dough sticks together.

Divide in half. Roll out to make 2 pies crusts. When using the crust for the top of the pie, sprinkle sugar on top and poke with a few steam holes. Crust can be frozen in balls and then defrosted and rolled out when ready to use. Makes 2 crusts.
