Welcome to Summer.  This is the Hemingway Daiquiri as he drank it at the El Floridita Bar in Havana, Cuba, from the early 1930s till Castro took power in 1959. Hemingway liked (it) a little tart, so they poured it without the sugar, but with a Maraschino on top.  On a light evening of drinking, they say he would drink 6 of these; on a big night, 12 doubles… hence the name, “Papa Doble.”

2 oz. White Rum

Juice of 2 small limes

Juice of 1/2 grapefruit

1/4 oz. Maraschino Liqueur

1/4 oz. Cane Syrup

Build all ingredients over crushed ice in a cocktail shaker.

Give a quick, sharp shake and pour into the Collins glass.
