What is the first step in making a Tito Mega Mule?

Filling the mug with ice is the first step in making a Tito Mega Mule because it ensures that the drink is chilled right from the start. A well-prepared mule benefits from having a cold base, as this enhances the overall refreshing experience and ensures that the flavors are properly integrated when the other ingredients are added. Ice helps to balance the temperature and maintain the drink's integrity as you mix in the other components, which typically include vodka, lime juice, and ginger beer later in the process. Starting with ice sets the stage for a more enjoyable and optimal drinking experience.
