I'm wondering how long I can keep baking powder before I have to throw it out.
I have an unopened can of baking powder with no expiration date. However it could be 7 or 8 years old. I'm just guessing but I don't really know. Can anyone help?
Thanks

(5,554 posts)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!

(32,641 posts)I'm planning to bake a cake tonight and I wasn't sure if my baking soda was good.
Thought I had a newer can, but this was all I could find in my pantry.
I will buy more when I get to the store, but it won't be tonight.

(32,641 posts)I buy baking soda rather often for different reasons, and it gets used up pretty quickly.
Baking powder is a different story. Haven't bought any in several years.

But it's from a store that I don't shop at anymore, so I know it's several years old.

(15,383 posts)Since they say you can open a box of it and put it the fridge to help with odors, I figure I should protect it from odors all the time.

(111,267 posts)My yardstick for determining whether or not the stuff is still good is clumping. If any of it clumps together, no matter its age, I know the bicarb and weak acid have reacted with each other to enough of a degree to produce adequate water to cause the cornstarch to start to clump. At that point, it's time to buy a new can of it. Please note I keep it tightly sealed, even here in the desert.

(68,582 posts)it tastes like they do. 2 TSP of Cream of Tarter, 1 TSP of Baking Soda, and 1 TSP of cornstarch. So it is a 2-1-1 ratio...you can make any amount you want...way cheaper too.
