Baking powder and baking soda are chemical leavening agents, but they are not the same. Baking soda is pure sodium bicarbonate, which needs an acid and liquid to activate. Baking powder contains sodium bicarbonate along with an acid (usually cream of tartar) and a drying agent (like cornstarch). This means baking powder only needs a liquid to activate. Using one instead of the other can affect the taste and texture of your baked goods.

FAQs & Answers

  1. Can I use baking soda instead of baking powder? Baking soda requires an acid and a liquid to activate, so it cannot be substituted directly for baking powder without adding an acid like lemon juice or vinegar.
  2. Why does baking powder contain cornstarch? Cornstarch acts as a drying agent in baking powder to prevent the acidic and alkaline components from reacting prematurely.
  3. How do baking soda and baking powder affect baked goods? Baking soda can cause a metallic or bitter taste if not balanced with acid, while baking powder provides a balanced rise since it contains both acid and base.
