What is the first step in preparing the Blue Raspberry Lemonade?

The correct response indicates that the first step in preparing the Blue Raspberry Lemonade is to fill a 20oz tumbler with shaved ice. Starting with shaved ice is essential as it creates a refreshing base for the drink, keeping it chilled and enhancing the overall texture. By establishing this foundation at the outset, you ensure that each subsequent ingredient is layered properly and mixed effectively, allowing the flavors to meld beautifully. The process of layering also has an aesthetic appeal, making the drink visually inviting.

This initial step is crucial because without the shaved ice, the drink would lack the necessary chill to be refreshing. Once the ice is properly packed into the tumbler, other components, such as the blue raspberry lemonade and any garnishes like a lemon wedge, can be added in a way that complements the icy base.
