What is the primary garnish for a Margarita cocktail?

The primary garnish for a Margarita cocktail is a lime wedge. This choice aligns with the traditional preparation and serving of Margaritas, which typically feature fresh lime juice as a central ingredient. The lime wedge not only complements the flavors of the drink by adding a zesty element but also serves as an aromatic garnish that enhances the overall experience.

The associated salt rim is indeed an important characteristic of a Margarita, as it adds a contrasting flavor that enhances the drink; however, it is considered more of a preparation technique rather than a garnish. Other options such as a cherry or mint leaf are not typical garnishes for Margaritas and would be more commonly associated with different cocktails. The lime wedge, therefore, remains the definitive garnish that reinforces the identity and traditional presentation of the Margarita.
