Sweet mousses are typically made with whipped egg whites, whipped cream, or both, and flavored with one or more of chocolate, coffee, caramel, puréed fruits, or various herbs and spices, such as mint or vanilla. In the case of some chocolate mousses, egg yolks are often stirred into melted chocolate to give the final product a richer mouthfeel. Mousses are also typically chilled before being served, which gives them a denser texture. Sweetened mousse is served as a dessert, or used as an airy cake filling. It is sometimes stabilized with gelatin.
