โญ Baking Soda + Vinegar (Best Vegan Option)
1/4 teaspoon baking soda + 1/2 teaspoon vinegar per 1 cup of meat mixtureBaking soda reacts with vinegar to produce carbon dioxide gas, which helps aerate the meatloaf mixture. This combination mimics the leavening effect of yeast without fermentation.
Add baking soda directly to the meat mixture and vinegar just before baking to ensure the reaction occurs during cooking. Use mild vinegar (like apple cider) to minimize flavor impact.
This substitute can lighten texture but may impart a subtle tang, which can complement or slightly change the flavor profile of the meatloaf.
