1. Pulse flour and salt in a food processor to combine. Add butter, cut into small pieces, and pulse until mixture forms coarse crumbs with some larger pieces remaining, about 10 seconds.
2. With machine running, add ice water in a slow, steady stream until dough just holds together without being wet or sticky, no longer than 30 seconds.
3. Divide dough in half; flatten and shape into disks, and wrap each in plastic. Refrigerate at least 1 hour or overnight.
