From the French word meaning foam or froth, mousse is a food that incorporates air bubbles to give it a rich, airy texture. Mousse can be prapared sweet, served as a dessert, or savory. Cold dessert mousses are usually made with pureed fruit or flavored with chocolate. These desserts get their fluffiness with beaten egg or whipping cream. They are sometimes fortified with gelatin.

Hot, savory mousses are usually made with fish, meats, foie gras, vegetables or even cheese. These hot mouuses get their texture from beaten egg whites.
