For such a consistently popular cocktail, the Manhattan doesn’t have a consistent origin story. The only consensus is that it originated in New York City’s most famous borough no later than 1882. While the Manhattan Club may have created the cocktail (or at least took credit for it), some sources identify an unknown bartender at the Hoffman House bar as the creator. Surviving Prohibition and the changing tastes of the drinking public, the Manhattan deserves its reputation as a classic cocktail.
Combine in a mixing glass with ice, stir with energy and style worthy of New York City, and strain into a chilled glass, preferably martini or coupe. Orange peel and/or Luxardo cherry garnish optional.
The Manhattan is a remarkably flexible cocktail. The 2:1 ratio between the bourbon or rye and sweet vermouth isn't set in stone. Depending on the whiskey's strength and the drinker's preferences, you may want to adjust the ratio. As with other drinks cocktails calling for vermouth, e.g. the Martini, make sure your vermouth is fresh. With the proliferation of bitters on the market, you can use different bitters and have equally spectacular results.
