In a large bowl, stir together the flour, salt, and sugar. Place the ice in the water and set aside.
Cut in the cold butter with a pastry cutter or by hand, rubbing the pieces of butter between your thumb, index, and middle fingers. Once the pieces are no longer lager than about a peanut, begin to flatten the pieces of butter in sheets between your palms. Be careful not to over-work the butter or let it get too warm.
Working with only a couple tablespoons at a time, add in about 3 to 4 tablespoons of the water along with the vinegar. Stir together using a wooden spoon or even just a clean hand in the bowl. The dough should appear fairly shaggy and not sticky. Once you can squeeze a few pieces together and they hold, the dough is done being mixed. Do not over-mix.
Shape the dough into a disk. Wrap in plastic and refrigerate for at least a couple of hours, or overnight (preferably).
Once ready, bring the disc out of the refrigerator and allow to rest for about 10 minutes. Liberally flour the work surface and begin to roll out the dough, working from the center out – rotating the dough after each roll. Roll the dough until about ¼ inch thick and about 12 to 13 inches in diameter.
Gently roll the dough around the rolling pin and transfer to a 8 or 9 inch pie tin. Fit the dough into the bottom of the tin and up the sides, allowing for about an inch of overhang. Trim with kitchen sheers, crimp or press the edges to the pie plate, and place back in the refrigerator for 30 minutes.
Meanwhile, pre-heat oven to 425 degrees.
When the crust is cold, tightly line the dough with foil (making sure to cover the top edges). Fill with pie weights and bake for 20 to 30 minutes, until set but not very browned. Remove the pie from the oven. Carefully lift out the foil and remove the pie weights. Completely cool before adding the filling.
