Which step is not included in the preparation of the Tall Double Chocolaty Chip Frappuccino?

The preparation of a Tall Double Chocolaty Chip Frappuccino involves several specific steps that contribute to the drink's signature flavor and texture, which includes adding mocha sauce, incorporating java chips, blending the frappuccino base, and finishing it with whipped cream on top.

When considering the steps involved, adding frapp refers to the process of combining the frappuccino base with coffee or other flavorings. However, the term 'frapp' is not a standard term used in the preparation process. Instead, the drink is created by blending ice, milk, and the frappuccino base along with any additional ingredients like mocha sauce and java chips.

In this context, the other options represent well-defined components of the preparation. Mocha sauce is essential for giving the drink its rich chocolate flavor. Java chips add a crunchy texture, enhancing the overall experience, and topping the drink with whipped cream is a classic finishing touch that adds creaminess and visual appeal. Therefore, adding frapp, while related to the blending process, does not accurately describe a specific step in the official preparation of this beverage.
