Baking powder and baking soda are essential ingredients when it comes to baked goods like biscuits, muffins, cookies and cakes.
But they don’t last forever – over time, they’ll both lose their potency and won't provide your recipes with the leavening action they need.
Here’s how to tell if baking powder and baking soda are still up to the job:
BAKING POWDER: HOW TO TEST IT
• Add one teaspoon of baking powder to one-third cup of hot water.
• If the mixture immediately bubbles, the baking powder is still effective enough to use. If not, it’s time to toss it.
BAKING SODA: HOW TO TEST IT
• Add one teaspoon of baking soda to 3 tablespoons of vinegar.
• If the mixture quickly fizzes up, the baking soda is still potent enough to use. Otherwise, it’s time for a new box.
