In a medium or large bowl, whisk together the flour, granulated 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 with a few larger chunks as well. Using a knife or your fingertips, stir in the apple cider vinegar and vodka until large clumps begin to form. Add in the ice water 1/2 Tbsp at a time until you can form the ball into a dough. Use your fingertips to pinch together any dry bits into the dough, sprinkle with water if needed to bring all the dough together into a ball. Shape the dough into a flat disc and wrap in plastic wrap. Chill for 30 minutes to 1 hour.
