tips to make Sourdough Discard Banana Bread

- Make sure not to overmix the batter; it should be just combined to keep the bread fluffy.
- For added texture, consider mixing in chopped nuts, chocolate chips, or dried fruit.
variation
You can add spices like cinnamon or nutmeg for extra warmth. Substituting half of the all-purpose flour with whole wheat flour can also add a nutty flavor and more nutrition.
FAQs
-
Can I use fresh bananas instead of overripe bananas?
- It’s best to use overripe bananas as they are sweeter and provide moisture, but you can use fresh bananas in a pinch—just add a little extra sugar.
-
Can I use a different type of flour?
- Yes, you can use whole wheat flour or gluten-free flour. Just note that the texture and flavor may change slightly.
-
What can I do if I don’t have golden syrup?
- If you don’t have golden syrup, you can brush the top with honey or maple syrup for a similar glossy finish and sweetness.
