There are many versions of the Creole Cocktail. My favorite looks a lot like a Sazerac: whiskey, curaçao, and bitters, with a fragrant nose of absinthe.
Brandy, curacao, lemon, and bitters: the Brandy Crusta is the prototype of the modern sour, and a forerunner of the Sidecar. More historic marker than living cocktail, it's a drink that's important to know if you take your cocktails seriously. And it tastes good. Why did it disappear?
New Orleans' Ramos Fizz: Old Tom Gin, heavy cream, egg white, sugar, lime and lemon juices, sparkling water — and the hallmark orange flower water.
Another New Orleans original, the Vieux Carré Cocktail: rye whiskey, Cognac, sweet vermouth, Bénédictine and bitters.
