In a large bowl, whisk together the all purpose flour, 1 Tbsp granulated sugar, and salt. Add the butter, and using your fingertips, rub the butter into the flour until you’re left with pea-sized pieces of butter coated in flour. In a measuring cup, stir together the water, ice, vanilla extract, and vodka. Add this mixture 1-2 Tbsps at a time to your bowl of pastry dough and stir with a knife until the dough just begins to come together (this should be about 6-10 Tbsp–be careful not to get it too wet!).
