Which ingredient is commonly found in a Mojito?

In a Mojito, mint is the signature ingredient that gives the cocktail its distinctive flavor and refreshing aroma. The Mojito traditionally consists of five main components: white rum, sugar (traditionally sugar cane juice or simple syrup), lime juice, soda water, and fresh mint leaves. The mint is muddled with the sugar and lime juice to release its essential oils, before the rum and soda water are added, creating a vibrant and aromatic drink.

While cilantro, thyme, and basil are all herbs that can impart unique flavors in various culinary uses and cocktails, they do not appear in the traditional Mojito recipe. Cilantro is often used in Mexican cuisine; thyme is a common herb in Mediterranean dishes; and basil might be found in drinks like a Basil G & T, but none of these herbs match the refreshing profile created by mint in this classic cocktail. Thus, mint is unequivocally the correct answer for this question.
