How to Make Your Own Aluminum-Free Baking Powder

As I've learned the hard way, the expiration date on baking powder is optimistic. To make 1 tablespoon of baking powder, you can use these 3 ingredients. You can make more or less by just keeping the same proportions. If you make a large amount for future use, you'll have to mix it up well and figure an expiration of less than a year. Most of my recipes require a tablespoon of baking powder. Easy to just add these 3 ingredients each time. Can't be any fresher.
