In a large bowl, place flour. Using a pastry blender, begin to cut in butter. Add salt and sugar. Continue working butter into flour until mixture has the consistency of course-ground cornmeal. (The cubes of butter should now be smaller than the size of a green pea.) Add ¼ cup water, and continue working mixture until dough begins to come together. Shape dough into a disk, and wrap in plastic wrap. Refrigerate for 2 hours.
