Supposedly created by an American engineer in the late 1800s and named after a beach near Santiago, Cuba. The original recipe specifically calls for BACARDI rum and recipe is as follows (for 6 pax):
Yes, those Tex-Mex ice blended, sickly sweet (more like diabetes inducing!), fruity versions which we are all too familiar with are basically bjuice of 6 lemons6 teaspoons of sugar6 Bacardi cups2 small cups of waterplenty of crushed ice
This is Hemingway's favourite drink. Legend has it that he goes through 12 glasses in a sitting (citation required). He liked it so much he created his own version aptly named after himself which has added maraschino and grapefruit juice, and even more rum (because he was a known alcoholic), with no sugar (because he was diabetic).
