Invented in the 1920s by Harry MacElhone, this is an iconic Prohibition era cocktail. Most of the great prohibition cocktails were not invented in the United States but in other countries. It was hard to stock a bar in the States then and the booze one did get was usually trash. This one comes from Harry’s New York Bar located in Paris, France. Established by Scottish Bartender Harry MacElhone, Harry’s New York Bar was one of the hot spots in Paris for traveling Americans who wanted to get drunk.
