Why does baking soda sometimes give an undesirable taste?

    After Taste Sometimes you might experience a bitter after taste or a soapy taste in your baked goods and you will attribute it to the baking soda. Do you know why it happens? If you carefully scan the ingredients list you will most definitely find that there is one thing missing completely or not enough of it. Can you guess what ingredient it is? It's the acidic ingredient. Without an acidic component baking soda cannot have the intended chemical reaction.

    Heat will cause the baking soda to react but only half the carbon dioxide will be released. Without an acidic ingredient, a strongly alkaline sodium carbonate is produced thereby giving a bitter taste to the baked goods.
