In a medium bowl, whisk together the flour, sugar, and salt. Using your finger tips, rub in the cold cubes of butter until you have mostly pea-sized chunks of butter covered in flour; you should have a few larger chunks as well. Using a knife or your fingertips, stir in the vodka and apple cider vinegar until large chunks of dough begin to clump together. Add in the ice water 1-2 Tbsp at a time until you can form the dough into a ball. Shape into a flat disc and wrap in plastic wrap. Chill for 30 minutes to 1 hour.
