Step 1
Make the crust: Place flour and butter into the freezer for 30 minutes before starting the crust process. In a large food processor, pulse flour, sugar, and salt until combined. Add butter and pulse until pea-sized and some slightly larger pieces form. With the machine running, add vinegar, then ice water into the feed tube, 1 tablespoon at a time, until the dough starts to come together and is moist but not wet and sticky (test by squeezing some with your fingers). The mixture will be crumbly.
