The drink was supposedly invented by an American mining engineer, named Jennings Cox, who was in Cuba at the time of the Spanish–American War. It is also possible that William A. Chanler, a US congressman who purchased the Santiagoiron mines in 1902, introduced the daiquiri to clubs in New York in that year. The original Daiquiri was a simple mix of sweet and sour . Rum, Lime & Sugar the key ingredients served straight up without ice. Over the years extra flavours have been added and also frozen versions from machines. How ever the best and most popular way is a Strawberry flavoured Daquiri served straight up or over ice.
