How to make an Ernest Hemingway Daiquiri or Papa Doble

Dave from Citizen Wine Cheese and Chocolate Bar shows how he makes an Ernest Hemingway Daiquiri or Papa Doble

Here is one Hemingway Daiquiri recipe:

6 tablespoons fresh grapefruit juice
2 ounces white rum
1 teaspoon maraschino liqueur (or maraschino cherry juice)
1 teaspoon fresh lime juice
½ cup crushed ice
Slice of lime
In a blender, blend all ingredients at high speed until thick. Serve in chilled martini glass, garnished with slice of lime.

Here is a second Hemingway Daiquiri recipe from when Hemingway drinks with A. E. Hotchner in his book Papa Hemingway: A Personal Memoir:

2 jiggers Bacardi or Havana Club rum
(1 jigger = 1 1/2 ounces)
Juice of 2 limes
Juice of 1/2 grapefruit
6 drops of maraschino (cherry brandy)
Fill a blender one-quarter full of ice, preferably shaved or cracked. Add the rum, lime juice, grapefruit juice and maraschino. Blend on high until the mixture turns cloudy and light-colored (See Islands in the Stream, page 281 for a more Hemingway-esque description).
Serve immediately in large, conical goblets
