Prepare the dry ingredients: In a large mixing bowl, whisk together 2 1/2 cups organic all-purpose flour, 1 tsp sea salt, and 1 tbsp organic cane sugar (if using).
Cut in the butter: Add 1 cup (2 sticks) of chilled, cubed organic unsalted butter to the bowl. Use a pastry cutter or your hands to mix until the butter is evenly distributed, forming pea-sized pieces in the flour.
Add water gradually: Begin adding 6 tbsp of ice-cold filtered water one tablespoon at a time, mixing gently with a fork after each addition. Add just enough water for the dough to hold together when pressed
Form the dough: Turn the dough out onto a lightly floured surface and gather it into a ball. Divide it in half, flatten each half into a disc, and wrap in parchment paper or beeswax wrap. Refrigerate for at least 1 hour, or up to 2 days.
Roll it out: When ready to use, roll each disc out on a lightly floured surface to fit your pie pan. Gently transfer the dough to the pan, pressing it into the edges. Trim and crimp the edges as desired.
Use as needed: For pre-baked crusts, prick the bottom with a fork and bake at 375°F (190°C) for 15-20 minutes. For filled pies, follow your specific recipe's baking instructions
