This recipe is a bit of a cheap slam-dunk, but what else should I have done with an abundance of Luxardo and grapefruit juice? I'll plead for an exception based on the name, which perfectly captures this hybrid of a Hemingway Daquiri and a White Lady.
2 oz gin (Old Tom was a nice choice for this one)
1/2 oz Luxardo maraschino
3/4 oz red grapefruit juice
1/2 oz lemon juice
Shake and strain into an old-fashioned glass filled with crushed ice. Garnish with a cherry if you feel fancy.
In the end, this is a lot more like an Aviation than either of the parent drinks. It's a bit too obvious a combo, really; there's got to be another name for this, but I like mine.
