Transfer the dough to a lightly floured surface, sprinkle lightly with flour, and using floured hands, shape the dough into a 9-inch square. Cut the dough into 9 squares and transfer to the prepared pan, spacing about 1/2 inch apart. Sprinkle evenly with the remaining 1 tablespoon of sugar. Bake 12 to 14 minutes, or until the tops of the scones are lightly browned. Serve immediately.
