Punt e Mes
Garnish with a proper cherry.
It's sort of like a Red Hook but even yummier. I'm still impressed with Aperol's ability to stand up to more butch boozes. Totally hit the spot! Hugh @ Eastern Standard gets points for his fine psychic ability, making this recommendation after I'd had a Hanky Panky, and only having met just that night.
A variant can be found in this later entry.
Postnote on 10/16/10: While at Craigie on Main last week, I was able to look through their drink Rolodex and get the recipe for this drink: 1 1/2 oz RH100 rye, 1 1/2 oz Aperol, 1/2 oz Luxardo Maraschino, 1/2 oz Punt e Mes.
