Combine the flour, salt, and sugar in a mixing bowl. Add the shortening and work it in with your hands until the mixture resembles coarse crumbs. Add the water, 1 tablespoon at a time, and work it in with your hands. Add only as much as you need for a smooth ball of dough. Wrap the dough in plastic wrap and refrigerate for at least 30 minutes.
