Directions
                          1. In a large bowl, stir together flour, brown sugar, baking powder, cinnamon, salt, baking soda, nutmeg, and ginger; set aside.
               2. In a medium bowl, combine milk, pumpkin, egg  yolks, butter, and, if desired, orange peel. Add pumpkin mixture all at  once to flour mixture; stir just until combined (batter should be  lumpy).
               3. In a small bowl, beat egg whites with an electric  mixer on high speed until stiff peaks form (tips stand straight). Gently  fold beaten egg whites into pumpkin mixture, leaving a few puffs of egg  white.
               4. Heat a lightly greased waffle baker. Pour some of  the batter onto the waffle grids. Close lid quickly; do not open until  done. Bake according to manufacturers directions. When done, use a fork  to lift waffle off grids. Repeat with remaining batter.
               5. Serve waffles immediately or keep warm in a  loosely covered ovenproof dish in a 300 degree F oven. If desired, serve  with Cider-Honey Syrup. Makes 16 (4-inch) waffles.
