It's a delicate balance between gas production, flavor, và browning for most baked goods, which is why you often see both used in the same recipe. Even professionals must experiment khổng lồ get that ratio just right, and it's another reason why most baking requires adherence lớn exact recipe ingredients and measurements.


Like most kitchen ingredients, baking powder & baking soda eventually thua trận their potency.
