make your own baking powder
To make your own baking powder – some say with fewer metallic undertones than the commercial stuff – mix one part baking soda to one part cornstarch and two parts cream of tartar.

A recipe I need to remember the next time I forget to buy some when we’re out.
What is the role of the corn starch here? I’ve always just done one part baking soda to two parts cream of tartar (I never buy baking powder). I might try it with corn starch next time–I hadn’t ever heard this.
Wow, thanks for the tip! So easy. No reason to buy the pre-fab stuff. I just learned about the aluminum in baking powder recently.

The addition of starch is to help keep the mixture dry, and therefore prevent the chemical reaction from taking place prematurely (Only really matters if you are making a larger batch to store for later use). It also adds some extra bulk to the mixture making it easier to get the correct quantities.
Oh, now THERE’s a great tip.
