Use this to make our Rustic Three-Cherry Tart.
Pulse flour, salt, and sugar in a food processor to combine. Add butter; process until mixture resembles coarse meal, about 10 seconds. With machine running, add ice water in a slow, steady stream through feed tube until dough just holds together (no longer than 30 seconds).
Shape dough into a disk. Wrap in plastic, and refrigerate at least 1 hour (up to 2 days).
Dough can be kept frozen for up to 1 month.
