1/2 teaspoon coarse salt
1/2 teaspoon sugar (if using in a sweet pie, otherwise, omit)
½ cup (1 sticks) unsalted butter, cut into tbsp size slices
¼ or less ice water
Combine flour, salt, and sugar in the bowl of a food processor. Add butter, and process for a few seconds until the mixture resembles coarse meal, about 10 seconds. Add ice water in a slow, steady stream, pouring it through the feed tube just until the dough holds together. Do not process for more than 30 seconds.
Turn dough out onto a work surface. Flatten, and form a disk. Wrap, and refrigerate at least 1 hour before using. Makes one crust.
