Maybe you already know this and I'm just bringing you some stale old news. But for years and years I have been buying baking powder and then feeling a little vulnerable when I was running low.

But then when we were grain-free I discovered that it's easy-peasy to make at home. And it's been a solid five years since we purchased the stuff. It's a great option if someone if your family has food allergies or sensitivities, too, since you're in control of the starch that goes in.

All you need is baking soda, cream of tartar, and starch of your choice (I use tapioca).

The instructions below might just save you from a pre-holiday cooking marathon freak out.

Here's how:

Homemade Baking Powder Recipe (corn-free option)

2 parts cream of tartar

1 part baking soda

1 part tapioca starch (or arrowroot or corn starch)

Combine ingredients using the ratios above, sift and place in a labeled glass jar. (Since cream of tartar comes in those teensy little canisters I normally start by measuring what we have of that and working my way out from there.)

And… you're done.

You're welcome! Happy baking.
