What is mousse commonly made from?

Mousse is commonly characterized by its light and airy texture, which chiefly comes from the incorporation of whipped cream or beaten egg whites. These components create the signature fluffiness of the dish. The technique involves aerating these ingredients, allowing them to trap air bubbles, resulting in a voluminous and creamy concoction.

While other options may mention ingredients used in variations of mousse, the foundational base of a classic mousse primarily relies on whipped cream or egg whites to achieve its signature consistency. For example, chocolate mousse frequently uses both melted chocolate and whipped cream, while fruit mousse may rely on puréed fruit with whipped cream or egg whites for its texture. This essential characteristic makes whipped cream or egg whites the correct choice in this context.
