White Vinegar (Best Option)
1 tablespoon per 1 tablespoon of lemon juiceWhite vinegar is a strong acid (acetic acid) that effectively reacts with baking soda to produce carbon dioxide, which helps the quick bread rise. Its acidity level is comparable to lemon juice, making it an excellent leavening activator.
When substituting, use the exact volume to maintain the liquid balance in the batter. Avoid using flavored or malt vinegar as they can alter the taste.
The final bread will have a slightly tangier but neutral flavor, closely mimicking the brightness lemon juice imparts without adding citrus notes.
