What is the primary garnish in a Mojito?

The primary garnish in a Mojito is mint leaves. The Mojito is a classic cocktail that features fresh mint as a key ingredient, both in terms of flavor and presentation. When preparing a Mojito, fresh mint leaves are typically muddled to release their aromatic oils, contributing to the drink's refreshing taste. After mixing the cocktail, additional mint leaves may be added as a garnish, enhancing the visual appeal and providing a pleasant aroma.

Mint is not only integral to the cocktail's flavor profile but also symbolizes the drink's refreshing quality, making it the standout choice among the garnishes listed. The other options do not align with the traditional preparation of a Mojito; hence, they do not serve the same purpose or enhance the drink as effectively as mint.
