Baking powder and baking soda are both leavening agents used in baking. Some recipes call for baking powder, baking soda or a combination of both. When both are used in a recipe, the baking powder does most of the leavening and the baking soda is used to neutralize the acids and add tenderness. Baking powder does lose it’s potency after a while, so I mix up small batches whenever I need them.
I started mixing my own baking powder quite a while ago. I ran out once and didn’t want to run to the store. I knew you could mix it up at home, but had never done it. So I looked up a recipe on-line. It’s so quick and easy, I’ve been mixing it up fresh ever since. I also like homemade baking powder because I can make it aluminum free. Homemade baking powder is not double acting like most of what you buy in the store, so it’s important to bake the item right away. (Jennifer brings up a good question in the comments about cookies that call for chilling – I chill the dough, sometimes overnight and have never had issue with cookies not rising, so I guess baking right away isn’t necessary).
Homemade Baking Powder
1 teaspoon baking soda (I use aluminum free)
2 teaspoons cream of tartar
1 teaspoon corn starch *optional
Mix all ingredients in a small jar. If you are using right away, there is no need to add corn starch, *add if you’re planning on storing baking powder for future use.
It costs a little less than 18 cents for each batch you make following this recipe, if I didn’t add corn starch it would cost only 14 cents per batch. I’m pretty sure I couldn’t buy organic aluminum free baking powder for this price and it certainly wouldn’t be as fresh. I’ve always had great results with this homemade baking powder. So next time you’re in a pinch and need baking powder, mix some up at home. You’ll be surprised by how quick and easy it is.
Have you ever mixed up your own baking powder?
