I was reading an old occult-action thriller of the Weird Tales variety, The Brood of the Witch-Queen (1918) by Sax Rohmer. During a scene at a masked ball in Cairo, our protagonist says to his ailing companion:

"I prescribe a 'tango'" said Sime. "A 'tango' is --?" "A 'tango'," explained Sime, "is a new kind of cocktail sacred to this buffet. Try it. It will either kill you or cure you."

Naturally I had to mix up a Tango cocktail before continuing! 

This is a less sweet, equally complex version of Satan's Whiskers. The ingredients are almost the same, with more gin and less of the sweet stuff, and no bitters. 

I made this one with Silo gin from Vermont, reasoning that the apple taste of that fruit-forward gin would play well with the OJ and the triple sec. It was very good, but now I want to try it with one of those spicier gins from Maine, or the Nashoba Perfect 10 to see how they play with the sweet and dry vermouth combination.
