In a bowl, whisk together flour and salt. Use a fork or your fingers to work the grated butter into the flour until it resembles coarse crumbs.
Stir in cold water, one tablespoon at a time, until the dough starts to come together. It should be slightly sticky but not wet. Kneed until your dough comes together and roll into a ball.
Roll out your dough on a lightly floured surface into a 12-inch circle.
Press the dough into a greased 9-inch pie dish, trimming any excess. Crimp the edges if desired.
(Optional) Preheat oven to 375°F. Prick the bottom with a fork and bake for 10 minutes before adding your filling.
