Yes, baking soda and baking powder do go bad. But there is an easy way to tell if you need to toss that container in your cabinet and buy a new one. For baking powder, add about 1/4 tsp powder to about 1/2 c hot water. If it bubbles, it’s good. For baking soda, add about 1/4 tsp of vinegar to 1/2 c hot water, then add about 1/4 tsp of soda. If it bubbles it’s good. If either of them don’t bubble, time to head to the store.
Happy Holiday Baking!
