Shake all the ingredients with ice. Strain into a chilled cocktail glass. Garnish with the flamed orange peel.
The contemporary recipe for the Cosmopolitan goes back to the test-marketing of Absolut Citron. I've heard an unsubstantiated rumor that a woman named Cheryl Cook invented it in South Beach, Miami, though I was given credit for inventing it by New York magazine (and other publications that cited the New York article as a source). Well, I didn't. What I did do was popularize a definitive recipe that became widely accepted as the standard. The drink )rst appeared on menus in the late 1980s, )rst in New York City at the Odeon in TriBeCa, and )rst in San Francisco at the Fog City Diner; of course, both locations claim to have invented the drink. I put it on my menu at the Rainbow Room in 1996. Shortly after that, Madonna was spotted drinking one, and overnight I was getting calls from as far away as Germany and Australia for the recipe. I added the additional touches of Cointreau and the 5amed orange peel for garnish and presented it several times on television around the country. Now, it is certainly the most recognized drink in the world, next to the classic Martini. But to go back even further: Ocean Spray Cranberry Juice has promoted spirits with their products aggressively for years, and from 1956 to 1970 they were featuring a series of cocktails, one of which was made with 1 ounce of vodka, 1 ounce of cranberry juice, and a squeeze of lime, called the Harpoon. Add some Triple Sec or Cointreau and you have a Cosmopolitan.
