Mix Dry Ingredients: In a large bowl, whisk together the flour, sugar, and salt.
Incorporate Butter: Using a box grater (large-hole side), grate the cold butter directly into the flour mixture. If you don’t have a grater, slice the butter into thin pieces and work it into the flour using your hands or a pastry cutter.
Create Pea-Sized Crumbles: Using your hands, quickly mix the flour and butter together until the mixture resembles coarse crumbs with pea-sized pieces of butter.
Add Ice Water: Gradually add the ice-cold water, a tablespoon or two at a time, mixing after each addition. Depending on humidity, you may not need the full ½ cup. Stop adding water when the dough holds together without crumbling.
Form the Dough: Turn the dough onto a clean surface and gently shape it into two flat discs. Wrap each disc tightly in plastic wrap and refrigerate for at least 1 hour.
Roll Out the Dough: When ready to use, remove from the refrigerator and let sit for 25-30 minutes. Lightly flour your rolling surface and roll out the dough, lifting occasionally to prevent sticking.
Use or Store: Roll out the dough to fit your pie dish and proceed with your recipe. If not using immediately, refrigerate for up to 3 days or freeze for up to 3 months in a freezer-safe bag.
