In the bowl of a stand mixer fitted with the paddle attachment, combine the flour, salt, sugar and butter. On low speed cut the butter into the flour until you have some larger pieces but most of the butter has worked into the flour. You will notice that the flour will change color and be slightly darker.
Stop the mixer and pour the vodka over the top of the crust. Turn the mixer back on low and slowly pour the water over the crust. Mix on low until the flour has hydrated but a coheasive dough has not yet formed.
Turn out onto a countertop and press gently until a dough forms. It will be a little wet, but that is ok! Divide the dough in half. Press out into disks and wrap in plastic wrap.
Refrigerate until cold, at least 2 hours and up to 3 days. Alternatively you can freeze it for up to 2 months. Thaw it in the refrigerator before using. Make sure to keep it cold!
Notes
Makes enough for 2 single-crust pies or 1 double crust pie
