Measuring and Freshness Tips

Measuring Tips

When you measure flour, stir the flour first.  Flour can get "packed down" in the bag or canister.   Don't measure over your mixing bowl. 

  • Using a spoon, fill the measuring cup with flour.  Overfill the cup a little.
  • Be sure that you do not "pack" down the flour.  You could have too much flour in your recipe if you do. 
  • Use the flat edge of a knife to scrape off the extra flour.

Get the Most from Your Baking Soda and Baking Power

Baking powder and baking soda are essential to any successful baking adventure, so it is important to know how to keep these ingredients at their best and when it is time to toss them out. 

Both baking powder and baking soda have a “best if used by” date somewhere on the container.  This is usually 18-24 months out from when it was purchased. 

If you are unsure if your baking powered or soda are still fresh enough to be used in your baked goods, test it out.  To test if baking powder is still good, combine 1 teaspoon of baking powder with 1/3 cup of warm water.  If the mixture bubbles, the baking powder is still good and will have adequate rising power.

To test baking soda, place 1 ½ teaspoons of baking soda in a bowl and add one tablespoon of vinegar.  If it fizzes, it is still usable.

If you find yourself with an overabundance of baking powder or baking soda, they can be frozen without the rising qualities being harmed.  However, be conscious of where you store these items.  Storing them near a heat source such as an oven may lead to low quality performance of the product.

Finally, make sure all of your measuring equipment is clean and dry before putting it into the baking powder or baking soda container.  If measuring spoons are not clean, or still have water on them, it could contaminate the product, and give them a shorter shelf life.
