Combine Dry Ingredients: In a food processor or mixing bowl, add the gluten-free flour and sugar. Pulse or whisk to combine.
Add Cold Butter: Cut the cold, salted butter into small cubes. Add it to the flour mixture and pulse (or use a pastry cutter) until the mixture resembles coarse crumbs with pea-sized pieces of butter throughout.
Add Vinegar and Water: Drizzle in the apple cider vinegar. Then, gradually add the cold water, 1 tablespoon at a time, pulsing or stirring gently after each addition. Use just enough water for the dough to hold together when pressed.
Form Dough: Turn the dough out onto a piece of plastic wrap. Gather it into a ball, then flatten it into a disc. Wrap it tightly in the plastic wrap and refrigerate for at least 30 minutes (or up to 1 hour) to let it firm up.
Roll Out Dough: Once chilled, place the dough between two pieces of parchment paper or on a floured surface. Roll it out into a circle about 1/8 inch thick and 1–2 inches larger than your pie pan.
Transfer to Pie Pan: Carefully place the dough into your pie pan, pressing gently to fit it into the bottom and sides. Trim any excess dough around the edges and crimp or shape the edge as desired.
Chill and Bake: If the recipe calls for a pre-baked crust, chill the shaped crust in the pie pan for 10–15 minutes. Then, prick the bottom with a fork OR don’t prick the bottom (always go according to your recipe's instructions) Bake according to the recipes instructions.
Line the Crust: Cut a piece of parchment paper or aluminum foil large enough to cover the crust and extend up the sides. Gently press it down onto the crust, covering the bottom and edges.
Add the Beans: Pour dried beans (or rice) onto the parchment or foil, filling the crust about halfway up the sides. Distribute the beans evenly so they press the crust down and hold it in
Blind Bake: Bake the crust with the beans in the oven according to the recipe’s instructions—usually for 15-20 minutes at 375°F (190°C), or until the edges begin to turn golden.Do show the baked crust in the step-by-step.
