Test baking soda and baking powder using this simple method. Test Baking Soda and Baking Powder


These simple procedures will let you test baking soda and baking powder for freshness and is worth your time if you have these products around for very long.  I do a lot of baking during the holidays and throughout the year but I still check often to make sure my ingredients are fresh.  This could save you from having a recipe flop and wasting a bunch of ingredients.

Test Baking Soda

1 tablespoon white vinegar

1/2 teaspoon baking soda

Add baking soda to vinegar.  If mixture does not fizz the baking soda is not good.


Baking Powder:

2 tablespoons warm water

1/2 teaspoon baking powder

Mixture should become foamy with bubbles.  If you do not get this reaction, the baking powder is not good.

  1. Thank you. I did not know about the baking soda. Good to know.

  2. I need to know if you have a starter for a diabetic person? It would be appreciated it. Thank you,.

  3. Sue Erskine says:

    Thank you for that information.. I also use S.R Flour a lot, but over here, no salt in our flour.. Add your own.. Have plain flour too, of course, and some recipes do say not to use SR, but needs a raising agent.. I will keep your informative information

  4. Good idea. However, I stick to self-rising flour and don’t have to worry about it. I use Baking Soda for cleaning-does good job on stainless steel sinks. Happy New Year.

    • The Southern Lady says:

      That’s good Jann as long as you use the flour fairly soon because these ingredients can go bad in the self-rising flour as well. Self-rising flour also contains salt as compared to all-purpose and some people need to cut salt. Happy New Year to you and your family.

    Never thought about it, and now that I don’t do as much baking, I thank you for a lesson I didn’t know.
