All you have to do is drop a little bit of the baking soda or baking powder into hot water (and vinegar if testing baking soda) and look for a bubbling reaction — if there’s fizzing, it’s still good to use!
Can you test baking powder for freshness?
If you haven’t bought a fresh can recently, you can check the freshness of your baking powder with a very simple test: Mix one cup of hot water with 2 teaspoons of baking powder. If there’s an immediate fizzing reaction that dissipates all of the powder, you’ll know it still works.
How do you test baking powder to see if it still active?
To check if your baking powder is still active, pour 1/4 cup boiling water over 1/2 tsp baking powder. If it bubbles, it’s still good. If not, it’s no good! If it foams when you pour over boiling water, the baking powder is active!
How long does baking soda and powder last?
Baking powder and baking soda are two essential ingredients that are commonly found in every household and seem to last forever. While they tend to have long shelf lives, eventually they start to lose their potency. Typically, both can last up to 6 months to a year.
Can you use expired baking powder for anything?
Since baking powder is basically just baking soda with some extra leavening and reacting agents in it for cooking, when it “expires” for your baking uses, you can still use it as baking soda (sodium bicarbonate). It can be used as a cleaning agent for scrubbing stains in sinks and on countertops.
How do you know when baking soda goes bad?
The fresher the soda, the larger the reaction. So, place a few tablespoons of vinegar in a bowl and sprinkle in a teaspoon of baking soda. If it immediately hisses and forms fizzy bubbles, you’re good to go. If the reaction is just a small fizz, your baking soda should not be used for baking.
What happens when you use old baking powder?
Expired Baking Powder Effects

Does expired baking powder taste bad?
