Not sure if your baking powder and baking soda are past their expiration date? This is how you check it

Must Try

You start making a cake, pie or cookies in good spirits , but when you check your baking powder or baking soda, there is slight doubt. The best before date is tight and that means a high chance of a failed end result. How do you check whether your baking powder or baking soda can last another round? We explain it to you.

Baking powder and baking soda over the date

Both baking powder and baking soda can be stored for about six months to a year. And we don’t like to throw it away. While we like to be inventive when it comes to finding solutions, there’s one thing you shouldn’t do: replace one with the same amount of the other. Because even though they both often make a difference between a successful or a failed baking, it is indeed a different product.

baking powder vs. baking soda

Because the baking powder is, as it were, diluted, the same amount of baking soda is not equally strong. You will also always have to add an acid, which will make the end result taste different. So you will never achieve exactly the same result, but you can actually replace it, provided you make the right calculation. In this article you can read how.

Checking the Shelf life

Our colleagues from Kitchn also wondered how you can check whether your baking powder and baking soda can last for a while and went to investigate. As it turns out: it only takes you a minute to be sure of your case. Both baking powder and baking soda are, in fact, chemical leavening agents that react to temperature and other factors. And all you have to do is test to see if these chemicals still work.

Baking powder

What you need

  • Baking powder or baking soda
  • Measuring cup
  • Hot water
  • A teaspoon to measure (you’ll need 1/4 teaspoon)
  • White or apple cider vinegar (when testing baking soda)

This is how you test whether your baking powder or baking soda is past its expiry date

First, fill your measuring cup with 120ml of hot water. Are you testing baking soda? Then add a quarter teaspoon of vinegar. Are you testing baking soda? Then you can skip that step. Then add a quarter teaspoon of baking soda or baking powder. Do bubbles appear immediately? Then you can happily continue baking. No bubbles? Unfortunately, that really means a return trip to the supermarket.
