Note: This recipe makes a single crust. If you need both a top AND bottom crust, double the recipe.
In a medium bowl, mix the 1 cup + 2 tbsp flour and salt together. Add half of the oil and use a fork to combine the flour mixture until even crumbs form.
Pour in the rest of the oil and the ice water and use the fork to gently bring it together. You want to handle the dough as little as possible, so gently mix a bit with a fork and then use your hands to bring it together just enough to form into a ball.
If you made a double recipe for a two-crust pie, divide it in half and let one ball of dough rest under plastic wrap until you're ready to prepare the top crust.
Roll out the dough. Prepare two sheets of wax paper on a smooth surface. Place the ball of dough in the center of a piece of wax paper, and place another sheet of wax paper on top. Use your hand to flatten into a round disk.
Using a rolling pin, roll out the dough evenly in all directions until it is about 1.5 - 2 inches wider than the pie dish. I like to flip it over at least once during this process, to ensure that the underside is smooth and no wax paper is wrinkling up.
Transfer the pie crust to the pie plate. One trick is to peel off the top sheet of wax paper, then lightly set it back down. Then flip the whole thing over and gently peel off what was the bottom sheet. This ensures that the pie dough is loose and will easily transfer to the pie pan. Next, gently invert it onto the top of the pie pan, centering it, and carefully peel off the wax paper.
With your hands, ease the crust down into the sides of the pie pan.
Now you have a couple of options. You can add a pie filling now before shaping the edge of the crust, or you can shape it first.
