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.
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.
