    Baking with Sourdough Discard

    Not only are they moist and sweet, but these banana muffins also have an amazing texture thanks to the sourdough starter in the recipe.

    Recently, I’ve been baking up a ton of sourdough bread.

    We've been trying some pretty unique sourdough recipes too.

    Next time, we'll be making sourdough discard crackers. And I also have a new recipe for sourdough pizza crust in the works.

    We even made our own sourdough starter without yeast as part of our homesteading and homeschooling unit. Plus I've been experimenting with freezing and dehydrating sourdough starter too.

    My kids absolutely love bananas, so I'm always looking for new banana recipes that are tasty and nutritious too, like these healthy chocolate banana muffins.

    Part of the ongoing process of keeping sourdough means feeding the starter. And also discarding about half of the sourdough each time you feed it.

    And I don’t like waste. So over the next little while, you’ll see a few more sourdough discard recipes, like this one for sourdough chocolate chip mini muffins.
