โญ Lemon Juice (Best Vegan Option)
1:1 (1 tablespoon lemon juice per 1 tablespoon white vinegar)Lemon juice contains citric acid, which reacts with baking soda similarly to acetic acid in white vinegar, producing carbon dioxide to leaven the cake. This chemical reaction is crucial for the cake's rise and tender crumb.
When substituting, use fresh lemon juice for best results and avoid bottled lemon juice with preservatives that might affect flavor. The acidity level is close enough to white vinegar to maintain the balance in the batter.
The final cake will have a slight citrus brightness that enhances vanilla without overpowering it, maintaining the expected texture and rise of the original recipe.
