Baking powder and baking soda are not the same thing. Baking soda is a single ingredient—sodium bicarbonate—which requires an acid to activate. Baking powder contains sodium bicarbonate and an acidic agent, making it self-rising. Use baking soda in recipes with acidic components, and baking powder in recipes without added acid.

FAQs & Answers

  1. What is baking soda used for in baking? Baking soda is used as a leavening agent and requires an acidic ingredient like lemon juice or buttermilk to activate and help dough rise.
  2. Why is baking powder called self-rising? Baking powder contains both sodium bicarbonate and an acid, allowing it to activate on its own without needing additional acidic ingredients.
  3. Can I substitute baking powder for baking soda in recipes? Substituting baking powder for baking soda is possible but may affect texture and rise since baking powder contains additional acids and fillers.
