Place the flour, sugar, and salt in a food processor. Pulse a couple of times to combine. Then, add the cold butter and pulse until the mixture resembles a coarse meal.
Transfer the mixture to a bowl and start adding ice-cold water a little bit at a time while mixing with a fork or rubber spatula. Add the water just until it’s possible to form a ball. The dough should look a bit crumbly but if you pinch a small portion of the dough, it should stay together. Finish bringing the dough together into a ball with your hands but don’t knead it.
Wrap the dough in plastic wrap and refrigerate for 40 minutes, overnight, or for up to two days.
Preheat the oven to 205C or 400F and prepare a 9-inch (23 cm) pie dish.
Roll the dough out into a circle on the surface dusted with flour, so it’s approximately 11- inches in diameter.
Place the dough into the pie dish (roll it loosely around your rolling pin and unroll it right into your pie dish), then gently press to attach the dough to the bottom and the sides of the dish but do not stretch it.
Trim the sides if needed or tuck the extra dough underneath itself, then crimp the edges or decorate as desired (read the post to see what you can do with the dough leftovers). Chill in the freezer for 10 minutes.
Then, use parchment paper to line the pie dish with the raw dough in it, so the paper hangs over the edges while covering them loosely. Place pie weights (dry rice or beans will work too) on top.
Bake for 20 minutes on the lowest rack, then remove the weights and the paper and bake for an additional 5-10 minutes or until the dough is cooked but hasn’t started picking up too much color yet. If the bottom has puffed up, gently press down with the flat bottom of a cup while still hot out from the oven.
Let it cool down completely before pouring in the filling.
