2 fluid ounces of a Spanish-style light rum
(recommended: Havana Club 3 Años of Cuba)
¾ fluid ounce of fresh lime juice
½ fluid ounce of fresh grapefruit juice
½ fluid ounce of maraschino liqueur
Make sure the lime juice is well-strained. Shake all of the ingredients with ice and double strain into a frozen cocktail glass.
Ernest Hemingway enjoyed Daiquiris with rum, fresh lime and grapefruit juice, and maraschino liqueur, as well as without any added sugar. Any Daiquiri using using those ingredients may fall under the umbrella of Hemingway Special variations. The above recipe comes from Punch Drink.
