- 3 oz Appleton Estate Jamaica rum
- 6 oz Fernet-Branca liqueur
- 17 3/4 oz Simple syrup
- 4 1/2 oz Fresh lemon juice
- 3 oz Fresh lime juice
- 3/4 tsp Fee Brothers lemon bitters
- 6 oz Water
Add all the ingredients in a medium-size metal bowl and stir.
Pour the liquid into a large freezer bag, and place it in the freezer until frozen for approximately 4 hours.
When ready to drink, massage the freezer bag by hand until it’s a wet, slushy consistency. If it’s not breaking up, run the bag quickly under hot water and massage some more.
Divide among four coupe glasses.
