In a separate bowl, beat the egg whites until stiff peaks develop. A handheld beater works well. Fold the egg whites into the batter and leave a few fluffs.
Bake at 375° F for about five minutes or until steam almost stops.
Serve hot with soft butter and heated real maple syrup.
Notes
A good belgian waffle iron with the ability to control the temperature is a must.However, don’t trust the temperature setting on the waffle iron, they are notoriously inaccurate.Use an infrared thermometer to directly measure the temperature of the waffle iron grid.
