A mousse gets its signature light, airy texture from aeration created by whipped egg whites and/or whipped cream. When you whip these ingredients, air is folded in and trapped in the fat or protein structure, forming a stable foam. This foam is then gently folded into a flavored base—such as melted chocolate, fruit purée, or a custard—to give the mousse its smooth, fluffy mouthfeel. Sugar helps with sweetness and can aid stability, but the essential element is the whipped foam that provides lift. Flour and milk, by contrast, create a denser pudding or batter, not the airy foam that defines a mousse. Sugar and salt are common flavorings in many desserts, but they don’t supply the foamed structure on their own. Chocolate chips and butter aren’t the defining components either; chips would disrupt a smooth texture, and while chocolate can be part of a mousse, the core texture comes from the whipped foam, not the chips or butter.
