There are several essential components that make up a traditional mousse. The first of these is the base, which is typically made from some type of dairy product, such as heavy cream or milk. This base helps to give the mousse its creamy texture and flavor. Another important component of a mousse is air, which is usually incorporated through the use of a whisk or an electric mixer. The third key ingredient in most mousses is a thickener, such as gelatin or cornstarch, which helps to stabilize the mixture and keep it light and fluffy. In this case, since we're using ready made whip, we don't need to add a thickener. Finally, many mousses also contain ingredients like pumpkin puree, chocolate or nut butters to add flavor and nutritional value.
