Was almost out of Baking Powder and found the recipe for making my own in Fine Cooking sometime ago and it is easy and I like knowing what is in mine and not any added chemicals. So thought I'd post it here and on the" What are you Baking" thread.
Homemade baking powder - From Fine Cooking Magazine
There are two reasons you might want to make your own baking powder:
1. You get to choose the ingredients that go into it (and can avoid acids that contain aluminum, which may result in a metallic taste).
2. It will be really fresh (because if the purchased kind is kept on the shelf too long, moisture from the air can cause the acid to mix with the baking soda, thereby neutralizing both).
Its simple to do. Mix two parts cream of tartar with one part baking soda and one part cornstarch. Store in a cool, dry place for up to several months. How long it lasts depends on how air-tight its stored, how often you open it, and the humidity.
To test the freshness of your baking powder, either homemade or purchased, add 1 tsp. to 1 cup of hot water. The mixture should bubble. If it doesnt, toss it.
