Is Bicarbonate of Soda the Same as Baking Soda?
Bicarbonate of soda and baking soda are the same ingredient—sodium bicarbonate. The only difference is the name: “bicarbonate of soda” is used in Ireland and the UK, while “baking soda” is the term in the US.
It acts as a leavening agent in baking. When combined with acidic ingredients like vinegar, lemon juice, or yogurt, it produces carbon dioxide, which helps cakes, breads, and muffins rise and stay fluffy. Unlike baking powder, it requires an acid to activate properly.
