Use this recipe to make Martha's Rum-Raisin Pie, Plum and Port Crostata, or Gateau Basque.
Pulse flour and salt in a food processor. Add butter, and pulse until mixture forms coarse crumbs with some larger pieces remaining, about 10 seconds.
With machine running, add ice water in a slow, steady stream just until dough holds together without being wet or sticky, no longer than 30 seconds.
Divide dough in half, and shape into disks. Wrap in plastic; refrigerate at least 1 hour or overnight. Dough can be frozen up to 1 month; thaw in the refrigerator overnight before using.
