Testing the potency of baking powder

To test the vitality of your baking powder, add a teaspoon of it to a third of a cup of hot water. If it foams and bubbles, it has enough oomph left. If it just sits there, it's time to run to the store or — here's a thought — you can make your own. Combine a tablespoon of baking soda with 2 tablespoons of cream of tartar and 1-1/2 tablespoons of cornstarch. It may not have the same potency as a good store-bought double-acting baking powder, but it will serve in a pinch.

Update: I just found a jar of baking powder that I had dated 2/2008 and I used this test on and it foamed and bubbled like crazy. Normally, I would have thrown it out because of the date, but it is apparently still good. Waste not, want not!
