Which ingredient is NOT typically found in a Mojito?

The ingredient that is not typically found in a Mojito is lemonade. A Mojito is a refreshing cocktail traditionally made with five key ingredients: white rum, fresh mint leaves, sugar (or simple syrup), lime juice, and soda water. The combination of these ingredients creates a light and refreshing drink that is known for its minty flavor and fizzy texture.

Lemonade is not part of the traditional Mojito recipe. Using lemonade would alter the drink's flavor profile significantly, as it introduces a sweet and tart citrus flavor that differs from the lime's tartness and the freshness of mint that define a classic Mojito. The other ingredients listed—mint leaves, soda water, and Malibu rum (if considering a variation)—are relevant to the standard preparation of this cocktail. Therefore, lemonade does not belong in a Mojito.
