1. In the bowl of a food processor, combine flour, sugar, and salt. Add butter and pulse until mixture resembles coarse crumbs, about 10 seconds. With the machine running, add ice water in a slow, steady stream until dough just comes together. Dough should not be wet or sticky. If dough is too dry and does not hold together, add a little more water.

2. Turn dough out onto a clean work surface and shape into a flattened disk; wrap with plastic wrap. Chill at least 1 hour before using.
