β Lemon Juice (Best Nut-Free Option)
1:1 (1 tablespoon lemon juice per 1 tablespoon white vinegar)Lemon juice contains citric acid, which reacts with baking soda to produce carbon dioxide, helping the quick bread rise effectively. The acid also tenderizes the gluten network, resulting in a soft crumb.
When using lemon juice, ensure it is fresh for optimal acidity. The slight citrus flavor is generally complementary to many quick bread recipes but may be noticeable in very mild-flavored breads.
Compared to white vinegar, lemon juice offers a similar leavening effect with a slightly brighter flavor, often enhancing the overall taste without compromising texture or rise.
