Baking Powder (Homemade)

By Hklbrries

Dear Heloise: Would you please tell us how to make baking powder at home?

Richard M, via email

If you run out of baking powder, a quick substitute is 1/4 teaspoon baking soda and 1/2 teaspoon cream of tartar. However, this does not store well, so don't make too much at one time. Another hint: How to tell if baking powder is still active? Put a teaspoon of baking powder in 1 cup of warm water. If it bubbles, it is still good.
