Feeding your sourdough starter, once considered a chore, might become a weekly task you look forward to since it means you can soon be making sourdough discard banana bread! Using your sourdough discard in banana bread gives the loaf a pleasant subtle tang that nicely balances the sweetness of the bananas and honey. Plus, this Sourdough Banana Bread will stay fresh longer than an ordinary loaf. It's an ideal way to use up ripening bananas and excess discard, and make yourself a treat: win-win-win!
