How is a traditional Cappuccino made?

A traditional cappuccino is defined by its specific balance of espresso, steamed milk, and milk foam. The correct preparation involves a base of espresso, topped with equal parts of steamed milk and milk foam. This combination creates a rich texture and enhances the flavor profile, allowing the coffee to shine through while being complemented by the creaminess of the milk.

In the context of the other options, using only steamed milk falls short of the traditional cappuccino's structural requirements since it lacks the essential milk foam that gives the drink its characteristic texture and experience. Similarly, a cappuccino is not meant to be topped with whipped cream; this is more typical of other coffee drinks like lattes or dessert-style beverages. Finally, a traditional cappuccino cannot be made without foam, as the foam is an integral component that defines its identity and contributes to the drink's overall composition and enjoyment. Thus, the choice that best aligns with the traditional method of making a cappuccino is to prepare it with half steamed milk and half milk foam.
