Lightly dust a work surface with flour. Turn the dough out onto it and knead 3 times. Pat or roll the dough into an 8-inch round, about 1 inch thick. Cut into 8 wedges, then transfer the scones to the baking sheet and refrigerate for 10 minutes. Bake for 18 to 20 minutes, or until browned. Let cool slightly on the sheet, then transfer to a wire rack.
