Overnight sourdough waffles made with the portion of your sourdough starter that you would otherwise discard. These waffles are light and airy on the inside and perfectly brown and crisp on the outside.Update: This recipe has milk in the overnight sponge and it is how I have been making the waffles for many years.While I personally continue to prepare them this way, I must note that leaving dairy out overnight goes against typical food safety recommendations. If that makes you uncomfortable, I have provided an alternative recipe in a downloadable PDF below the recipe card in the blog post.
Mix the sourdough starter, milk, and flour in a large bowl. Cover with plastic wrap and let sit on the countertop overnight.
In the morning finish the waffles:
Preheat your waffle iron.
Stir in the melted butter, egg yolks, salt, and baking soda.
Beat the egg whites until they have stiff peaks then gently fold them into the batter.
Pour the batter onto the preheated waffle iron and bake until crisp and golden, about 3 to 4 minutes.
Notes
Waffle irons vary in the amount of batter they use so you may end up with a different amount of waffles. The nutrition values are based on 10 waffles.
As noted above, if you are uncomfortable adding the milk to the overnight sponge, I have provided an alternative recipe in a downloadable PDF just below the recipe card in the blog post.
