Which ingredient is NOT typically found in crème Chantilly?

Crème Chantilly is a sweetened whipped cream that commonly includes heavy cream, sugar, and often vanilla for flavoring. The traditional components of crème Chantilly are focused on incorporating air into the cream to achieve a light and airy texture, along with sweetness from sugar and additional flavor from vanilla.

Egg whites are not a standard ingredient in crème Chantilly. While egg whites can be whipped to create meringue or used in other desserts to add structure or volume, they don't play a role in the creation of crème Chantilly. Therefore, the absence of egg whites aligns with the traditional recipe and purpose of this delightful whipped cream preparation.
