Baking powder how long

Properly stored, opened baking powder will generally stay at best quality for about 6 months. Is baking powder safe to use after the "expiration" date on the package? Yes, provided it is properly stored and the package is undamaged — commercially packaged baking powder will typically carry a "Best By," "Best if Used By," "Best Before," or "Best When Used By" date but this is not a safety date, it is the manufacturer's estimate of how long the baking powder will remain at peak quality.

How can you tell whether opened baking powder is still good to use? Baking powder and baking soda are two staples almost everyone has around that seem to last forever. But a lot of people don't know that they eventually start to lose their potency after enough time on the shelf. If you can't remember when you bought it, it's probably time for a new box. When baking powder expires, you'll definitely notice the difference after your baked goods all turn out flat. Same thing with baking soda, which is an ingredient in baking powder, though you'll have the added disadvantage of stinkier pets, books, and shoes.

The expiration date on the box isn't always accurate, but there's a quick way to test both baking powder and baking soda to see if they need to be replaced. Baking powder usually has a shelf life of about 9 to 12 months. Testing it is super easy. Just stir about half a teaspoon of baking powder into a cup of hot water. It will immediately start to fizz and release carbon dioxide gas if it's still fresh enough to use.

In the video below, I tested baking powder which was 6 months past its expiration date with baking powder still within its freshness date. Notice the difference in the bubbling and fizzing sound when stale baking powder is introduced to the hot water on the left versus when fresh baking powder is introduced to the hot water on the right.

Watch the video for instructions. If the baking powder is still good or fresh, the mixture should bubble instantly and vigorously. The baking powder should dissolve immediately and the dry powder is no longer visible. This baking powder is still good and you can use it in your recipes. If the baking powder is expired or stale, the mixture will just have a few bubbles, minimal fizzing and the powder will just float on top of the water. Sponge Cake Banh Bong Lan. Orange Chiffon Cake.
