The history and roots of the Mojito is unclear, but it's popularity has gained steadily over time and been a favorite of Ernest Hemingway, featured in a few films, and has been the continued classic cocktail of Cuba. Some stories state that the Mojito started as a medicinal drink to help curb disease and it has evolved over time to the drink we know and love today. It is traditionally made with white rum, lime, superfine sugar, and fresh mint, so those are the essential ingredients.
