Whisk together the flour, salt, and sugar in a large bowl until evenly combined.
Cut the cold butter into the flour using a pastry cutter or pulse in a food processor until the mixture looks like coarse crumbs with pea-sized butter pieces.
Stir together the vodka and ice water, then drizzle it over the flour mixture. Mix just until the dough looks shaggy and holds together when squeezed.
Turn the dough onto a lightly floured surface and gently press it together without kneading. Divide it into two equal portions and shape each into a flat disk.
Wrap each disk tightly in plastic wrap and refrigerate for at least 2 hours, or overnight, until firm.
Roll one dough disk into a ⅛-inch thick circle on a lightly floured surface, turning it often to prevent sticking.
Transfer the dough to a 9-inch pie plate, gently ease it into the corners, trim the edges, and crimp as desired.
Chill the shaped crust for 20 to 30 minutes before baking. Fill and bake according to your pie recipe, or blind bake with parchment paper and pie weights until the edges are lightly golden.
