Helpful Baking Tip: Make sure you are using the freshest ingredients for the best results. Even baking soda and baking powder will get old. To test baking soda for freshness, mix with a little vinegar. Mix baking powder with a little warm water. If they are fresh, they will bubble furiously. It’s time to replace them if you see little or no reaction.
