Nitrous oxide, commonly known as laughing gas, is also used in baking as a leavening agent. In baking, nitrous oxide is typically found in whipped cream dispensers, where it creates whipped cream by expanding and aerating the cream. When used in baking, nitrous oxide can be infused into batters or creams, creating a light and airy texture in the final product. It's especially popular for making mousses, foams, and certain types of cakes. The gas dissolves into the mixture, creating bubbles that contribute to a fluffy and delicate consistency in the baked goods.
