Add the flour, sugar, and salt to the bowl of your food processor (or a large bowl if you're making the dough by hand)
Turn the food processor on low speed and add the chunks of cold butter one at a time while the food processor runs until all the butter is added and the mixture resembles coarse crumbs.If making by hand, use a pastry blender or your hands to work the butter into the dough until the mixture is crumbly. Try not to handle the butter too much (the heat from your hands will soften it) - use quick movements and don't worry if some larger chunks of butter still remain. Add the vinegar and the water slowly as the food processor runs on low, just until the dough comes together and pulls away from the sides of the bowl. Depending on the weather and even on the brand of flour, you can use anywhere between 5 and 8 tablespoons of water. If making by hand, use your hands to form the dough gently and quickly using just enough water for the dough to come together. Dump the rough dough onto the counter, shape it into a disc and wrap it in plastic wrap, placing it in the fridge to chill for 45 minutes or overnight.
Remove the chilled pie dough from the fridge and let it sit for about 10 minutes before rolling. Roll out the ball of dough into a large circle using a rolling pin. Add some flour to the rolling surface and to the rolling pin, to prevent sticking and cracking. Peel the rolled out dough off the counter surface gently by rolling it backwards onto the rolling pin.
Transfer it to a 9-inch pie plate and gently press the dough into the bottom of the pie plate and over the edges (try for a 1-2 inch overhang if possible).
Trim any dough that hangs over the edge of the pie to 1-2 inches past the edge (try to keep the overhang amount even all the way around). Tuck any overhanging dough under and into the pie plate to create a clean edge.
If your pie plate has a wide edge, seal the edge of the pie by creating a fluted pattern - press into the edge of the pie from the outside with your left thumb and index finger while pressing into the edge of the pie from the inside with your right index finger. Do this all the way around the edge of the pie to create a fluted pattern (and see a tutorial HERE for how to create a beautiful fluted edge to your pies!)Place your prepared pie crust in the freezer for 10-20 minutes, or in the fridge for 30 minutes. Preheat your oven to 400℉ (200℃).
Remove the pie crust from the freezer, add foil or parchment paper and pie weights.
Bake at 400℉ (200℃) for about 15 minutes, then remove the foil and pie weights and bake for another 10-15 minutes until the crust is evenly browned.
