Manhattan In the early a "cocktail" connoted a drink mixed with bitters. The recipe for this one, which first appeared in Issue comes from Keen's Steakhouse in Manhattan. I actually prefer mine on the rocks.
Of course, the New Yorker for the Cocktail hour Whiskey, lime juice, grenadine and a touch off sugar. A New York Cocktail is another of the whiskey Cocktails that remind me of an Old Fashioned Cocktail.
