Whisk the gluten-free flour, sugar, and salt together in a large mixing bowl. Make sure the bowl is large enough that you can place your hands or a pastry cutter into it as you make the dough.
Combine the gluten-free flour and salt in the bowl of a food processor. Pulse three or four times to combine.
Transfer the mixture to a mixing bowl. Squeeze a handful. If it holds together, mix with a wooden spoon until a dough forms. If the handful falls apart, stir in an additional tablespoon of water until the dough forms.

The recipe was tested with Bob’s Red Mill and Cup4Cup Flour. Other gluten-free flour blends might not work as well.
Use a blend of half butter and half shortening for a flavorful and flaky gluten-free crust.
Be sure to use very cold water.
