What is a substitution for baking powder?

1. Baking Soda and Acid: Mix baking soda with an acidic ingredient like buttermilk, lemon juice, vinegar, or yogurt in equal amounts. This combination will create a reaction that produces carbon dioxide, which is what baking powder does.

2. Cream of Tartar and Baking Soda: Combine 2 parts cream of tartar with 1 part baking soda. This mixture is slightly less potent than baking powder, so you may need to use a bit more.

3. Self-Rising Flour: If you don't have baking powder on hand, you can use self-rising flour, which already contains baking powder and salt. However, keep in mind that this substitution may alter the taste and texture of your baked goods.

4. Sourdough Starter: For sourdough recipes, you can use sourdough starter instead of baking powder. The starter will produce carbon dioxide during the fermentation process, resulting in a similar effect to baking powder.
