Double Active Baking Powder Aluminum Free

Double Acting baking powder adds another dimension. Not only does it start reacting in the bowl as with baking soda and "single acting" baking powder, but it also reacts a second time when it is cooked. This is achieved by the addition of slower reacting acids to the single acting baking powder, which hardly react at room temperature. These only become active once they achieve higher temperatures. So it has a double action - once when subjected to moisture in the bowl and once when subjected to heat in the oven. This quality means that the rush to mix and get it into the oven is avoided, which is especially useful if there are many ingredients which need thorough blending.
