Can you use baking powder or baking soda after the expiration date?

Dry leavening agents (baking powder, baking soda) will probably be marked with a "best used" date and if stored tightly sealed they most likely usable beyond that date. Typically they last 6 months to a year but you can test the potency of baking powder or baking soda; here is how:

Test baking soda: mix 1/4 teaspoon baking soda with 2 teaspoons of vinegar and the mixture should bubble immediately; if not, replace it.

Test baking powder: mix 1 teaspoon baking powder with 1/2 cup hot water and the mixture should bubble immediately; if not, replace it
