Buttermilk Waffles
In a medium bowl, combine the flour, cornstarch, baking powder, baking soda, salt, and sugar. Whisk well. Add the milk, buttermilk, vegetable oil, egg, and vanilla extract. Whisk to blend well, so that few (if any) lumps remain. Set aside to rest for 30 minutes.
Preheat a waffle iron. Follow your waffle maker’s instruction manual for this, but my guess is that you’ll want to heat it on whatever setting is approximately medium-high. My waffle maker has a heat dial that runs from 1 to 7, and I turned it to 5. There’s no need to grease the waffle maker.
Pour an appropriate amount of batter into your hot waffle maker: this amount will vary from machine to machine, and you should plan to use your first waffle as a test specimen. Cook until golden and crisp.
Because this batter uses both buttermilk and milk, the texture is lovely, and the slight tangy quality of the waffles is a welcome addition.
This waffle works in any kind of waffle maker.
