In a food processor, or large bowl, add the flour and salt.
½ half of the cold butter and pulse several times or until all the flour and butter is covered and in small pieces. (If you’re not using a food processor, you’ll need to complete these steps using a pastry blender or large fork.)
Add the rest of the butter and pulse a few times again until everything is combined and in small coarse pieces.
Add the vodka to the mix and pulse several times to mix.
Add the ice water a Tablespoon at a time until the mixture JUST starts to come together. You should be able to pinch a small amount between your fingers and it’ll stick.
Dump the crumbs onto the counter and mold them into a ball. Divide it in half then wrap each individually in plastic and put in the refrigerator. One half can be frozen to use another time. Allow it to chill for an hour.
After an hour, preheat the oven to 350 degrees. Remove the crust and place on a lightly floured surface. Allow it to warm up just enough so that you can roll it out.
Roll the dough into a large circle that will extend beyond the pie plate by a few inches.
Place the dough into the pie plate and gently push the dough into the bottoms and along the sides.
Cut off the extra dough leaving an inch extra from the edges. Tuck the extra crust under the edge and crimp the edges all the way around.
Place aluminum foil in the bottom and up the sides of the inside of the shell. Fill with pie weights, (you can also use rice or sugar) and fill it to the top of the sides.
Bake for 40 minutes, then remove the shell to a wire rack to cool while you prepare the filling.
Increase the oven temperature to 400 degrees.
