BAKING POWDER AND BAKING SODA TESTS
BAKING POWDER
To test baking powder's effectiveness: mix 1 tsp (5 grams) baking powder with 1/2 cup (120 ml) hot water and the mixture should bubble immediately and vigorously. The fresher the baking powder, the more active the bubbles. If no reaction occurs or if the bubbles are weak, the baking powder is not strong enough to raise whatever you are planning to bake.
Store in a cool dry place and it should be replaced every 6-12 months.
BAKING SODA
To test baking soda's effectiveness: mix 1/4 teaspoon baking soda with 2 teaspoons of vinegar and the mixture should bubble immediately.
