Bicarbonate of Soda vs Baking Soda: Are They Actually the Same Thing?
If you enjoy trying recipes from different countries, ingredient names can sometimes slow you down. One question that comes up again and again is whether bicarbonate of soda and baking soda are two separate products or just different labels.
They are the same ingredient. Both names refer to sodium bicarbonate, a common raising agent used in baking. The difference is purely regional. In Ireland, the UK, and much of Europe, it’s called bicarbonate of soda. In the United States and Canada, it’s known as baking soda. Functionally and chemically, there is no difference at all.
Sodium bicarbonate works by reacting with acidic ingredients in a recipe. When combined with things like yogurt, lemon juice, vinegar, or buttermilk, it produces carbon dioxide. This reaction creates bubbles that expand in the oven, helping cakes, breads, and muffins rise and develop a lighter texture.
Many people confuse baking soda with baking powder, but they are not interchangeable. Baking powder already contains an acid, while bicarbonate of soda does not. Using the wrong one can affect both flavour and texture, so it’s always worth checking which ingredient a recipe specifically calls for.
