Which step concludes the preparation of a Venti Syrup Frappuccino Blended Creme?

The conclusion of preparing a Venti Syrup Frappuccino Blended Creme is to top the drink with whipped cream. This step is significant because it not only enhances the visual appeal of the beverage but also adds a creamy texture and rich flavor, which is a characteristic element of many Frappuccino drinks. The whipped cream serves as a finishing touch that elevates the overall experience, making it more indulgent.

After topping the drink with whipped cream, the other steps that might follow, such as adding a lid and serving with straws, are important but come after this key finishing touch. While blending and serving are essential parts of the preparation process, the addition of whipped cream is what truly completes the Frappuccino and aligns with Starbucks' presentation standards for these specialty beverages.
