Is there any difference between baking powder, baking soda and soda bicarb?
Of course there is a difference. Well kind of anyway. Soda bicarb and baking soda are the same thing. In some products that are leavened baking powder is used instead of yeast, as baking powder is more stable and quicker. What it does is once wetted and heated (double action) it gives off gases and leaven the product- think bisquits. Baking soda quite often is in baking powder, but baking powder also contains cream of tarter and other ingerients. Of course the uses of baking soda are way to long to list here. The uses of baking powder and baking soda are not the same and are not interchangable.
