What is the difference between baking powder, baking soda and bicarbonate of soda? What are their different applications?
Baking soda and bicarbonate of soda are different names for the same thing; in New Zealand, we mostly refer to it as bicarbonate of soda, but overseas, especially in America, it is referred to as baking soda. They aren’t interchangeable, but bicarbonate of soda and baking powder are both leavening agents. When included in a batter, the leavening agent causes air bubbles (produced by stirring, whipping or beating) to expand when cooked – causing it to ‘rise’.
