In a large mixing bowl, combine the sifted flour and salt. Whisk them together to ensure that the salt is evenly distributed throughout the flour.
Add the cold, cubed butter to the flour mixture. Using a pastry cutter or fork, cut the butter into the flour until the mixture resembles coarse crumbs with small pieces of butter throughout for flakiness.
Gradually add cold water, one tablespoon at a time, mixing gently with a fork after each addition until the dough starts to come together. Do not overmix.
Turn the dough out onto a lightly floured surface. Gather it into a ball, then flatten it into a disc. Wrap the disc in plastic wrap.
Refrigerate the dough for at least 30 minutes to solidify the butter for a flaky crust.
Remove the dough from the refrigerator and let it sit for a few minutes. On a floured surface, roll it out to about 1/8 inch thickness.
Carefully transfer the rolled dough to your pie dish. Gently press it into the bottom and sides of the dish, trimming any excess dough hanging over the edges.
If pre-baking, preheat oven to 350°F (175°C) and bake crust for 15-20 minutes or until lightly golden. Otherwise, fill immediately with your pie filling of choice.
