In the realm of cocktails, everything old is new again, and this combination of whiskey, sweet vermouth, dry vermouth, and bitters is no exception. Served in a cocktail glass, this classic potion, created by swirling the above ingredients and topped with a Maraschino cherry, has recently received a second wave of popularity, in partial thanks to those trendsetting gals of Sex and the City. Strong, urbane, and simple, it isn't just for your grandfather anymore. So go ahead, enjoy Manhattan—without the hassle of airport security!
