45ml Bacardi Superior Rum
15ml Lime Juice
5ml Grapefruit Juice
5ml Maraschino Liqueur
The Hemingway Daiquiri, also known as the Papa Doble, is one of those cocktails that are easy to get wrong. Fresh grapefruit juice can vary wildly in terms of acidity and sweetness, and with the small amounts under consideration, you can lose the flavour of grapefruit. In my personal opinion, I like to use more grapefruit juice than lime juice, and use the lime juice and additional sugar syrup to compensate for the variation in sweet/sour balance.
In terms of it’s history, the Hemingway was reportedly invented in Cuba, for Ernest Hemingway, who’s favourite cocktail, the Daiquiri, was slowly becoming poison for a man with diabetes. The sugar that is normally used in a Daiquiri is replaced with maraschino liqueur, which is as sweet with less glucose. Grapefruit juice is widely recognized for reducing the blood sugar level due to its low glycemic index.
