Mousse (pronounced /ˈmus/) is derived from the French word mousse which means “lather” or “foam”. A mousse is a stable prepared food that incorporates air bubbles to give it a light and airy texture. Depending on how it is prepared, it can range from light and fluffy to creamy and thick.A dessert mousse is a form of dessert typically made from egg and cream (classically no cream, only egg yolks, egg whites, sugar, and chocolate or other flavorings), usually in combination with other flavors such as chocolate or puréed fruit, although recipes with chicken liver or other savory ingredients also exist. Once only a specialty of French restaurants, chocolate mousse entered into American and English home cuisine in the 1960s.
