A mojito is traditionally made of five ingredients: white rum, sugar (traditionally sugar cane juice), lime, carbonated water and mint. Its combination of sweetness and refreshing citrus and mint flavors are intended to mask the potent kick of the rum, and have made this clear highball a popular summer drink. Many hotels in Havana also add Angostura bitters to cut the sweetness of the mojito; while a popular variation, it is not the original version created in La Bodeguita del Medio.
When preparing a mojito, lime juice is added to sugar (or syrup) and mint leaves. The mixture is then gently mashed with a muddler. The mint leaves should only be bruised to release the essential oils and must not be shredded. Then rum is added and the mixture is briefly stirred to dissolve sugar. Finally, the drink is topped with ice cubes and sparkling water, mint leaves and lime wedges are used to garnish the glass.
