Apple Cider Vinegar (Best Option)
1 tablespoon per 1 tablespoon of balsamic vinegarApple Cider Vinegar works well because it has a similar acidity level and a subtle fruity flavor that mimics the complexity of balsamic vinegar without overpowering the zucchini or spices. The acidity helps activate baking soda or powder, contributing to proper rise and texture.
When using apple cider vinegar, ensure it is raw and unfiltered for the best flavor. Avoid overusing it as too much acidity can make the bread taste sour. Adjust sweetness slightly if needed to balance the tang.
The final zucchini bread will have a slightly lighter tang compared to balsamic vinegar but will retain moistness and a well-rounded flavor profile, making it the closest match.
