Pulse flour, salt, and sugar in a food processor. Add butter, and pulse until coarse crumbs form, about 10 seconds.
With machine running, add ice water in a slow, steady stream just until dough holds together and is not wet or sticky, no longer than 30 seconds.
Divide dough into two portions, and shape each into a disk. Wrap in plastic; refrigerate at least 1 hour or overnight. Dough can be frozen up to 1 month; thaw in refrigerator overnight before using.
Note: This recipe makes enough for two nine-inch pies or one double crust pie.
