Preheat oven to 425°F.
In a food processor, pulse 1 1/2 cup all-purpose flour, scant 1/4 cup granulated sugar, and a good pinch of salt until well combined.
Add 9 tablespoons cold unsalted butter, cut into small pieces, and pulse until the mixture resembles coarse crumbs.
With the machine running, add 3 tablespoons of cold water and process until the dough starts to come together in a ball. You may need to add a little more water if the dough is too dry or a little more flour if it is too sticky.
Transfer the dough to a lightly floured surface and shape it into a flat disk about 5" in diameter. Wrap it in plastic wrap and refrigerate it for at least an hour or up to two days.
When you are ready to use the dough, roll it out on a lightly floured surface to a thickness of about 1/8". Fit the dough into a 9-inch pie pan, trimming the excess dough leaving about 1/2" to fold under to allow for shaping the edges.
Prick the bottom and sides of the dough with a fork to prevent it from puffing up during baking. Cover the dough with foil. Fill foil with pie weights or dried beans.
Bake the crust in the preheated oven for 15 to 20 minutes or until dough is set and starting to lightly brown. Remove from oven. Let it cool completely on a wire rack before filling it with filling.
