1. Make Pastry
Combine the flour, sugar, and 1 teaspoon salt in a food processor. Pulse to combine. Add the butter and pulse until the butter resembles small peas.
With the processor running, drizzle in the water. Continue to pulse to form a dough. If needed, drizzle in additional water, 1 tablespoon at a time, until the dough comes together.
Shape the dough into a disk, wrap tightly in plastic wrap, and refrigerate for at least 2 hours or up to 3 days. (If refrigerating more than 2 hours, let the dough warm up a bit on the counter before attempting to roll in step 6.)
