In the work bowl of a food processor, place flour, sugar, and salt; pulse until combined. Add cold butter, and pulse until mixture is crumbly. With processor running, add ¾ cup (180 grams) ice water in a slow, steady stream until a dough forms.
Divide dough in half, and shape each half into a disk. Wrap tightly in plastic wrap, and refrigerate for at least 30 minutes or overnight.
