The famed Ernest Hemingway’s Papa Doble daiquiri has been improperly made throughout the decades due to some misinformation, so here’s the clarification. There have been a number of cocktail books and bars that have described this drink as being made with lemon juice due to a copy editor’s mistake in the 1935 English translation of the recipe booklet Bar La Florida, published as a promotional giveaway. It should be made with fresh lime juice instead.
2 ounces white rum
1 ounce fresh lime juice
½ ounce fresh grapefruit juice
¼ ounce maraschino liqueur (not juice)
Can be combined in a blender with shaved ice and beaten until it’s foaming, but I prefer shaking the ingredients with ice in a cocktail shaker and straining into a chilled cocktail glass.
