How To Test If Baking Soda or Baking Powder Is Expired

THIS IS VERY HELPFUL AND I PLACED A COPY ON THE FRIDGE.

 

How To Test If Baking Soda or Baking Powder Is Expired

 

What You Need:

Baking powder or baking soda
Measuring cup
Hot tap water
1/4 teaspoon measuring spoon
White or apple cider vinegar (if testing baking soda)

 

Instructions:

  1. Measure out the water: Measure out 1/2 cup of hot tap water.
  2. Add vinegar: Baking soda needs an acid to get a reaction, so add 1/4 teaspoon of a simple vinegar like white or apple cider vinegar to the water if you're testing baking soda. If you are testing baking powder, you do not need to add any vinegar.
  3. Add baking soda or baking powder: Add 1/4 teaspoon of the baking soda or baking powder.
  4. Look for fizzing! After you add the baking soda or baking powder, look for an immediate bubbling or fizzing reaction. If it happens, your baking soda or baking powder is still good! If you see no bubbling, it's time get replacements.

Interesting.  I never thought it would expire... I have a huge box that I  have been using that must be 10 years old... seems to work just fine.

@SeaMaiden - It really depends on what you're using the baking soda for; if you're just using it as a cleaning agent, the age doesn't really matter, but if you're using it in baking, your results will not be as successful with old baking soda. You'll get a lot more rise/lift in your baked goods if you're using active, fresh baking soda, so I'd recommend checking it every 6-9 months to make sure you're getting a strong fizz when you expose it to vinegar (it reacts with acid to produce its leavening).

 

As for baking powder, I always check mine every three months since it loses its effectiveness much more quickly than baking soda and makes an even bigger difference in baked goods when it isn't fresh.

@loriqvc    good to know.  I only use it at this time to add to my hard boiled egg water to help the shells peel off easy.  Now I know that for baking I will only use fresh.

@GiantsLover, Thanks!  This is useful info.  I don't worry as much about my baking soda, but baking powder does not usually last very long.

The next time that I hear salt and ice together, it better be in a margarita!
