In the work bowl of a food processor, place flour, sugar, ginger, and salt; pulse 4 times to combine. Add cold butter; pulse until butter is pea-size. Add 6 tablespoons (90 grams) ice water; pulse until dough forms large clumps.
Turn out dough onto a lightly floured surface; divide in half. Shape into disks; wrap tightly in plastic wrap. Refrigerate for at least 1 hour.
