Pate Brisee for Sour Cherry Slab Pie

Place the flour, salt, and sugar in the bowl of a food processor, and process for a few seconds to combine. Add the butter, and process until the mixture resembles coarse meal, about 10 seconds. With the machine running, add the ice water in a slow, steady stream, through the feed tube, just until the dough holds together. Do not process for more than 30 seconds.

Turn the dough out onto a work surface. Divide in two with one piece slightly larger than the other. Place each half on a sheet of plastic wrap. Flatten, and form two rectangles. Wrap, and refrigerate at least 1 hour before using.
