In a large bowl, combine the flour, salt, and sugar.
Add the cold, cubed butter and use a pastry cutter or your fingers to work the butter into the dry ingredients until the mixture resembles coarse crumbs.
Slowly add ice water, one tablespoon at a time, mixing until the dough just comes together. Be careful not to overmix.
Form the dough into a disk, wrap it in plastic wrap, and refrigerate for at least 30 minutes.
Preheat your oven to 425°F (220°C).
On a floured surface, roll out the dough into a 12-inch circle. Carefully transfer it to a 9-inch pie dish, pressing it into the bottom and sides. Trim any excess dough and crimp the edges.
