Sourdough Waffles

I am a proud parent…of millions of Lactobacillus sanfranciscensis! I have successfully created a vigorous sourdough starter! Of course this comes with a bit of responsibility. Before you bake anything with it you have to refresh the start with some fresh flour and water the night before. I ended up with a bit of extra starter, so instead of letting it go to waste, I made waffles!

These are amazingly good waffles. I think they might even be worth trying to create your own sourdough starter just so you can try them. The waffles are crisp on the outside and fluffy on the inside. I am not sure of any of the science behind it, but there is clearly some magic going on. Since you start them the night before all you need to do in the morning is a little light mixing and then ladle the batter into the waffle iron. It is easy enough that my coffee addled brain was able to handle it.

  1. I already had the Starter going for hotcakes and got a yen for waffles instead. I found your instructions with the pictures, which I liked, and tried the recipe. They were great.
