Spread the gluten-free flour onto a flat work surface or Silicone Pastry Mat, then create a hollow or well in the middle.
Add the cold butter cubes, salt, sugar, and eggs. Blend the ingredients together with your fingers or a pastry scraper until they form rough, crumbly pieces.
Incorporate the cold water and mix until the mixture forms a cohesive dough. Shape the dough into a disk, cover it in plastic wrap, and chill in the refrigerator for at least one hour.
After chilling, roll the dough to your preferred thickness by rolling it out between two parchment papers. For even thickness, use measuring dough strips.
Transfer the dough into a pie dish or tart tins with the help of a rolling pin. Prick the bottom several times with a fork and then trim the edges. Before baking, place in the freezer or refrigerator to firm up for 20 minutes.
If needed, pre-bake large pie crust for 15-20 minutes at 190°C (375°F) in a preheated oven, then remove the weights and bake for an additional 10 minutes.
For small tart crusts, bake for 15 to 18 minutes.
Cool at room temperature before using.
