Chill the butter and prepare a bowl of ice water.

In a large bowl, whisk together the flour and salt.

Cut in the cold butter using a pastry cutter or your fingers until the mixture looks like coarse crumbs.

Add the ice water one tablespoon at a time, mixing until the dough just begins to come together.

Form the dough into a ball, divide into two discs, wrap, and chill for at least an hour.

Roll out the dough on a floured surface and transfer to your pie dish.

Bake according to your specific pie recipe.
