How to tell if your baking powder is still fresh.

You are right in the middle of creating a culinary master piece.  Your mouth is watering as you reach for the last ingredient your recipe requires.  In your hand is a container of baking powder, recovered from way in the back of your cupboard.

You find yourself  wondering when you used this stuff last.  Heck, you wonder when you bought it.  How long does baking powder last, anyway?  All you need is to put dead baking powder in what you are making and have the entire thing flop.   You sniff it.  But what is baking powder supposed to smell like, anyway?   You taste a bit.  That’s didn’t help, either.

Test to see if your baking powder is still fresh. If not, use this recipe to whip up a new batch!

How do you know if your baking powder is still good?


To find out if your baking powder is still good, simply drop a teaspoon of the stuff into a cup of hot water.  If it bubbles heavily, you are good to go!  If not, it’s time to get a new can of this wonderous stuff that make your baked goods rise.

But, you’re in your favorite holey jammie pants and that messy bun of yours is hiding more than just a bad hair day?

We’ve got ya covered.  Here’s a simple replacement recipe.

How To Make Your Own Baking Powder


Grab your favorite measuring spoons.  These are mine.  Are they not adorable?  Don’t tell anyone, but my Mom and all of my married girls are getting these for Christmas.

Next, get out these common baking ingredients found in most any pantry, especially ones created with prepping in mind.    One is a leavener, the other is an acid that will activate the baking soda to get your baked goods to rise.

Mix 1 teaspoon baking soda with 2 teaspoons cream of tarter.  Ta-da!  Problem solved!

Want to make a big batch and store it?  Just stick to the ratio of 1 part baking soda to 2 parts cream of tarter.

But now you’ll want to add one part corn starch or arrow root powder too.  This addition to your  recipe  will absorb any moisture and keep your newly created baking powder from clumping.

Plus, there will be NO aluminum to worry about!

  1. I didn’t know it bubbled in hot water. I was going to say add it to vinegar to see if it bubbled! Visiting from the Sustainable Sunday Hop!
