Hemingway’s Shotgun

OK, I just invented a cocktail that needs a name.

I’m sitting here listening to the inimitable Eric Taylor singing Hemingway’s Shotgun.

Now, as you know, Hemingway was known for his Daiquiris. This is kind a simple, strong, mutant Daiquiri, which I henceforth dub the Hemingway’s Shotgun:

2.5 oz Plantation Artisanal Original Dark Rum (moderately priced but extremely good!)
1 oz fresh squeezed Grapefruit juice
1/4 oz vanilla simple syrup
extra credit: a maraschino cherry

shake over cracked ice, serve up in a martini glass.
