Many people have had a one night stand at some point.  Are you thinking about one right now? Put aside your X-rated memories and focus on this cocktail creation from Brian Ireland and Demetri Karnessis. I discovered it in Chilled magazine.

2 ounces gin
.5 ounces Aperol
.5 ounces triple sec
Juice from 1/4 grapefruit

Combine in a shaker with ice, shake like (do you really need an analogy here?), and strain into a chilled glass.  Orange peel garnish optional.

Ireland and Karnessis use a particular brand of gin in the One Night Stand, but they don't call for a specific triple sec (a generic term for an orange liqueur). I like Cointreau, which I use in my Cancer Killer #1 and the Margarita. If you prefer a different triple sec, go for it.  Aperol, a part of the Naked and Famous and my Venetian Kiss, is a lighter amaro. Combine all of these spirits with the grapefruit juice, and you'll get an undeniably pink drink. If you like the One Night Stand, you might like similarly themed drinks such as the Intense Ginger Sutra and the Hanky Panky.

Enjoy the One Night Stand, but recognize too many could lead to something bad -- a hangover or something a Penicillin won't cure. Cheers!
