Preheat oven to 350° F. Get your 9-inch pie dish ready for action!
Stir flour and salt together in a large bowl. Cut butter into the dries using a pastry cutter or cold fingertips until butter is reduced to the size of small peas.
Sprinkle cider vinegar over the butter-flour mixture and stir with a fork. Slowly add ice water (don’t get ice into the crust mixture) until the dough can be gathered together. Add water slowly, so you don’t get it too wet.
Divide dough into a larger and a smaller ball. On a large cutting board or pastry cloth, roll the larger ball into a circle about 14-15 inches in diameter, using extra flour as you need it to keep the dough from sticking to the board. Save the smaller dough ball for patching the crust edges or for making cinnamon sugar roll ups. Or, you can make a smaller pie shell and freeze it for another time.
Fold the dough into quarters and then transfer it to a 9-inch pie dish. Open up to a full circle and crimp the pie edges to a pretty finished look. I usually flute the edge, but you can also use a fork or any method you like.
Poke holes all along the bottom and sides of the pie shell with a fork.
Lay a piece of foil in the center of the pie crust and put pie weights, or dry beans evenly over the foil. Partially bake the pie crust for 20 minutes. Then remove foil and weights and continue to bake for another 10 minutes, or just until the crust is beginning to brown. Remove from oven and cool.
