Among the many reasons cakes fall is the often-overlooked fact that the fault often lies with your baking soda or baking powder - OR BOTH!
"But", you say, "I keep the lid on the can of powder & the box of soda in a sealed ziplock!" That does not guarantee that your ingredients are at their best.
TIP: Before you bake next time, draw a cup of hot water and put 1 tsp of baking powder in it. IF it does not bubble vigously, the ingredient is garbage. The more active the bubbles, the better the powder.
The next time you want to bake and the recipe requires baking soda, put 2 tsp of vinegar in a shot glass and add 1/4 tsp of baking soda. IF it does not bubble vigorously, the ingredient is garbage. The more bubbles, the better the product.
As a rule of thumb, replace your baking powder & baking soda when you change the batteries in your smoke detectors, or change the clocks - at least every 6 months. Then you will eliminate one reason your cake fell...
