The late Frank Sinatra was a great American artist and icon. Among other things, he was a wonderful singer with a gifted voice, an ear for the nuance of language, and a captivating stage presence. He also was a pretty good actor (watch the first Manchurian Candidate movie). Thanks to Scott Deitche and his book Cocktail Noir for introducing me to the original cocktail, which I adapted. In honor of Ol' Blue Eyes, and his son (a performer who I had the privilege of seeing) who recently died, drink this.
2.5 ounces vodka (hello Zyr or Belvedere)
.5 ounces blue curacao
Juice from 1/4 lemon
.25 ounces super simple syrup
Jack Daniel's whiskey was Sinatra's alcohol of choice. While I would have liked to incorporate it into this cocktail, it's impossible to have a vibrant blue cocktail using Jack Daniel's as the base. Ol' Blue Eyes drank plenty of martinis over the course of his life, although I doubt he drank one that looked like this.
Just as Sinatra covered songs that other people made popular, I did the same with this cocktail. I substituted vodka, lemon juice, and super simple syrup for the gin and sour mix in the original.
When I perfected my version of the Frank Sinatra cocktail I put on some of his tunes and sang along. Fortunately I've much better at making drinks than I am at singing. Making and drinking cocktails with another person can be a special form of dancing. As Sinatra sang in Come Dance With Me -- for what is dancing, making love set to music, playin'.
