Place the dry ingredients–flour, sugar, and salt–into the food processor bowl. Pulse to blend.
Add the butter, scattering it around the bowl. Pulse until coarse crumbs form and all the flour and butter are mixed.
Add three tablespoons of ice water. Pulse until small dough balls form. Test the mixture by squeezing a bit between your fingers. If it sticks together, it is ready. If it does not, add a teaspoon of water, pulse, and test again. Add additional teaspoonfuls of water (if necessary) until the mixture sticks together when tested with a finger squeeze.
Turn the dough out onto a lightly floured surface and, without kneading, gently squeeze it together to form a ball. Flatten it into a disk, cover it with plastic wrap, and refrigerate for at least an hour.
After it is chilled, set it out of the refrigerator for a few minutes or until you can roll it out. Use a rolling pin to roll it into a crust large enough to drape over the sides of the pie dish.
Use the rolling pin to roll up the crust and move it to the dish. Fit it to the dish without stretching it. Crimp the crisp by hand or with a fork. Then, cut off the excess dough.
Preheat your oven to 425°F. Prepare the crust for parbaking by adding pie weights or dried beans to prevent it from puffing up during baking. If desired, place a pie shield on the edges of the crust to protect them from browning too quickly.
Place the pie crust in the preheated oven and bake for 15 minutes.
Carefully remove the pie dish from the oven and take out the pie weights.
Return the crust to the oven and bake for an additional 2-3 minutes to further cook without the weights.
Remove the crust from the oven and let it cool while you prepare the filling.
