What is added to the shaker right before pouring in the shots for a tall double shot on ice?

When preparing a tall double shot on ice, ice is added to the shaker right before the espresso shots are poured in. This is crucial because the ice helps to chill the espresso quickly, ensuring that it is served at the ideal temperature. Adding the espresso shots directly onto the ice also helps to create a refreshing drink experience, as the heat from the shots melts the ice slightly while fully integrating the flavors.

Other options may involve flavoring or different types of beverages, but they do not pertain to the immediate preparation of the tall double shot on ice. The focus on adding ice first sets the foundation for the drink and ensures that the espresso maintains a balanced temperature and flavor profile.
