Bicarbonate of Soda and Baking Soda Explained: What’s the Real Difference?
When cooking or baking with recipes from different regions, ingredient names can be confusing. One of the most common questions people ask is whether bicarbonate of soda and baking soda are actually different products or just different terms.
They are the same thing. Both names refer to sodium bicarbonate, a widely used raising agent in baking. In Ireland, the UK, and many other countries, it’s known as bicarbonate of soda. In the United States and Canada, it goes by the name baking soda. Aside from the wording, there’s no difference in how it works or how it should be used.
Sodium bicarbonate helps baked goods rise by reacting with acidic ingredients. When it combines with things like vinegar, lemon juice, yogurt, or buttermilk, it releases carbon dioxide. This creates air bubbles that expand during baking, giving cakes, breads, and muffins a lighter texture.
Problems usually arise when bicarbonate of soda is confused with baking powder. Baking powder already contains an acid, so it behaves differently. Using one in place of the other without adjusting the recipe can affect both flavour and structure.
