1/3 daiquiri rum
1/3 grapefruit juice
1/6 Groseille Syrup (Red Currant Syrup)
This cocktail is credited to J. W. Fish, and its first appearance in print is in the W. J. Tarling’s, 1937 Cafe Royal Cocktail Book
Groseille (Red Currant) Syrup is not something many people keep in their bar supplies. Fortunately the Internet Cocktail Database has a link to a recipe to make your own (Groseille Syrup link). They also suggest Grenadine as a substitute, although I would recommend that you use only half the sweetener if you replace the groseille syrup with grenadine.
Here is a variation using simple syrup rather than groseille syrup
The Appleton Celebration
1 1/2 oz White Rum
3/4 oz London Dry Gin
1 1/2 oz Fresh Grapefruit Juice
1/4 oz Sugar Syrup
Add ingredients into a metal shaker with ice.
Shake until the outside of the metal shaker begins to frost
Strain into a chilled cocktail glass.
Garnish with lime slice
