Combine dry ingredients : In a food processor, combine flour, salt, and sugar; pulse to combine.
Blend in butter: Add butter; pulse until mixture resembles coarse meal, with just a few pea-size pieces of butter remaining.
Add water: Sprinkle with ¼ cup ice water. Pulse until dough is crumbly but holds together when squeezed with fingers (if necessary, add up to ¼ cup more water, 1 tablespoon at a time).
Divide dough: Transfer half of dough (still crumbly) onto a piece of plastic wrap. Form dough into a disk ¾ inch thick; wrap tightly in plastic.
Chill dough: Refrigerate until firm, at least 1 hour (and up to 3 days). Repeat with remaining dough. Makes 2 disks.
