⭐ Lemon Juice (Best Gluten-Free Option)
1 tablespoon lemon juice per 1 tablespoon white vinegarLemon juice contains citric acid, which reacts with baking soda to produce carbon dioxide, helping the bread rise effectively. Its acidity level is close to that of white vinegar, making it a reliable substitute in baking.
When using lemon juice, ensure it is freshly squeezed or high-quality bottled juice to avoid off-flavors. The citrus aroma can slightly brighten the bread’s flavor, so balance it with spices if desired.
Compared to white vinegar, lemon juice may impart a mild citrus undertone, which can enhance the overall flavor complexity of zucchini bread without compromising texture or rise.
