Baking Powder vs Baking Soda
Can you substitute baking soda for baking powder (and vice versa)?
No, no, no, no, no. And yes. Both substances are leavening agents, meaning they make baked goods rise, and baking powder contains baking soda, but they are two different products. Baking soda can be bitter unless combined with an acidic ingredient; baking powder is neutral, as it contains acidic cream of tartar. In a pinch, baking powder can replace baking soda, though be forewarned it may change the finished product. Baking soda can't replace baking powder unless you also add cream of tartar (2:1).
