1 c. all-purpose flour
1 tsp. baking powder
1/2 tsp. salt
1 tsp. sugar
1/8 to 1/4 tsp. cinnamon (optional)
1 c. milk
1 egg, separated
1/2 tbsp. butter, melted

Stir dry ingredients together in a bowl. Add egg yolk and milk to dry ingredients and beat together thoroughly. Beat egg white until stiff; stir 1/4 into batter to lighten it; add cinnamon; gently fold in remaining egg white. Pour a scant 1/2 cup of batter onto a heated waffle mold. Makes about 6 waffles.
