What is the final addition to a Tall Green Tea Frappuccino before serving?

The final addition to a Tall Green Tea Frappuccino before serving is whipped cream. This topping enhances the drink’s presentation and provides an extra layer of creaminess that complements the flavors of the green tea and any additional ingredients. The whipped cream also adds a visually appealing finish that is typical of many Frappuccino beverages at Starbucks. Utilizing whipped cream is a common practice for many blended drinks, as it not only boosts flavor but also enhances the overall texture and enjoyment of the beverage.

In the preparation of the Frappuccino, ingredients such as milk, classic syrup, and ice are added prior to the whipped cream, playing crucial roles in determining the drink’s base flavor and consistency. However, it's the whipped cream that serves as the final touch, making the drink ready for presentation and consumption.
