Although the classic Daiquiri is said to have been invented in 1898 in Cuba, the variation known as Banana Daiquiri was first made around the 1970s at St. Thomas’ Mountaintop bar, located in the U.S. Virgin Islands. The cocktail is made by blending dark rum, sugar, lime juice, banana liqueur, water, and peeled ripe bananas with ice until the combination becomes smooth and thick.
