Preheat your oven to 400 degrees.

In your 6 or 8 cup food processor place the flour, cubed butter, egg, sea salt and sugar. Run the food processor on high until a crumbly mixture forms.

Add the water 2 tablespoons at a time while the food processor is running on low until a dough ball forms. If you add too much water and the dough is sticky add a couple of tablespoons of gluten free flour.

If you are using a 9x13 pan place the dough into the greased pan and press out evenly with your hands. If you want two 9 inch pie crusts, divide the dough and roll each disc out between two sheets of parchment paper. Prick the dough with a fork and place pie beads or beans onto the pie crust to keep it from rising.

Bake at 400 degrees for 15 to 20 minutes. The pie crust will be lightly browned. Let the crust cool slightly before placing your pie ingredients in and cooking according to the pie recipe's directions.
