FAQs: Sourdough Discard Banana Bread

1. Can I use active sourdough starter instead of discard?

Yes, but it will slightly change the texture! Active sourdough starter has more fermentation power, which may make the bread fluffier. If using an active starter, reduce the baking powder slightly to balance the rise.

2. How should I store sourdough banana bread to keep it fresh?

Store it in an airtight container at room temperature for up to 3 days. For longer storage, wrap it tightly and refrigerate for up to a week or freeze slices for up to 3 months—just warm them up before enjoying!

3. Why use sourdough discard in banana bread?

Sourdough discard adds depth of flavor, extra moisture, and a subtle tang that makes banana bread even better! Plus, it reduces food waste while providing gut-friendly fermented benefits. Win-win!
