From Emeril Lagasse's book "Every Day's a Party"; posted for ZWT 5. From the intro to the recipe: "When the Sazerac was first created, it contained an imported cognac made by a company called Sazerac-Deflorge et Fils of Limoges, France. The mixture changed in the late 1870's, when American rye whiskey was substituted for the brandy." The original recipe is attributed to Antoine Amadie Peychaud, a Creole apothecary. It was originally served in an egg cup, known as a 'coquetier' in French. Some historians think the word 'cocktail' comes from a mispronunciation of the word. This recipe was provided by Marcelle Bienvenu after a newspaper assignment.
