In a large mixing bowl combine: the flour, corn starch, sugar, baking powder, baking soda, and salt. Mix well.
Melt the butter in the microwave and allow a few minutes to cool.
Take the egg and separate the yolk and the white. Mix the yolk in with the 1 cup of milk. Put the white into a mixing bowl.
Whip the white with a hand mixer until a stiff peak has formed when you turn the mixer upside down.
Add the melted butter into the milk/egg yolk mixture.
Make a well in the center of the dried ingredients and pour in the wet ingredients.
Mix it all together until it is just combined and there is no dry flour. Don't worry about it being lumpy, the lumps will cook out. You don't want to overmix the batter.
Gently fold in the whipped egg white into the batter.
Allow the batter to sit out while the waffle maker heats up. The batter will thicken some as the flour and corn starch hydrate.
Once the waffle maker is hot. Brush butter on both top and bottom of the waffle maker then add your batter. I cook mine about 2-3 mintues past when the light actually goes out on the waffle maker indicating it's done. I want the waffle to be darker brown in color and crispy so it's perfect for dipping.
Place the finished waffles on a cooling rack so that the bottoms don't get soggy. Keep making waffles until your batter is done.
Cut or break apart into waffle sticks for serving.
