1. Mix the dry ingredients:

• In a large mixing bowl, whisk together the flour, salt, and sugar (if using).

2. Cut in the butter:

• Add the cold butter to the bowl. Using a pastry cutter or your fingertips, work the butter into the flour mixture until it resembles coarse crumbs with some pea-sized pieces of butter remaining.

3. Add the water:

• Gradually add the ice water, 1 tablespoon at a time, mixing with a fork or your hands until the dough just comes together. Be careful not to overmix. The dough should hold together when pressed but not be sticky.

4. Chill the dough:

• Divide the dough in half, shape each half into a disk, and wrap tightly in plastic wrap. Refrigerate for at least 1 hour or up to 2 days.

5. Roll out the crust:

• On a lightly floured surface, roll out one disk of dough to fit your pie dish, about 1/8 inch thick. Gently transfer it to the dish, pressing lightly to fit. Trim the edges, leaving about 1 inch of overhang if adding a top crust.
• If using a top crust, roll out the second disk of dough.

6. Assemble and bake:

• Fill the pie with your desired filling, cover with the top crust (if applicable), and crimp the edges to seal. Cut a few small slits in the top crust to allow steam to escape.
• Follow the baking instructions for your specific pie recipe.
