Pudding is made with a milk and sugar base that is cooked with cornstarch to thicken it. Although it is light and creamy, their texture is denser then a mousse. Keskul - Turkish Almond Pudding and Kazandibi are great examples of a delicious homemade pudding. Mousse, is traditionally not cooked and made by mixing a flavor base into whipped egg whites or whipped cream. This makes mousse lighter and fluffier then a pudding, with nice air bubbles throughout.
