⭐ Lemon Juice (Best Nut-Free Option)
1 tablespoon lemon juice per 1 tablespoon white vinegarLemon juice is acidic enough to react with baking soda, producing carbon dioxide gas that helps the cake rise and maintain its tender crumb. Its acidity is close to that of white vinegar, making it an effective leavening agent in this context.
When substituting, use fresh lemon juice for the best flavor and acidity. Avoid bottled lemon juice with preservatives as it may alter the taste. Monitor the batter’s consistency as lemon juice is slightly more liquid than vinegar.
The final cake will have a slightly brighter, fresher flavor profile with a subtle citrus note, which many find pleasant and complementary to the traditional red velvet taste.
