How To Make Your Own Baking Powder
Most biscuits, muffins and quickbreads require baking powder. But what if you're all out? Not a problem — you can make your own baking powder using two common ingredients: baking soda and cream of tartar.
Unfortunately, if you don't have baking soda or cream of tartar, you're going to have to go to the store. While you're there, you might was well pick up all three items, just so you'll have them on hand. Just make sure you replace them every six months, or they'll lose their potency.
Whatever you do, don't try to substitute baking soda for baking powder. It's won't work. Here's an article that discusses the difference between baking soda and baking powder.
To make 1 tablespoon of baking powder:
- Measure 1 teaspoon baking soda and 2 teaspoons cream of tartar into a bowl.
- Mix until thoroughly combined and use right away.
If you need more, you can just double the recipe. If you need to store it for some reason, just add a teaspoon of corn starch (so that it doesn't clump up), and store it in an airtight container.
