There are seemingly a never ending list of national days, from national bow tie day (28th August) to world beard day (1st September). The 25th August marked Whiskey Sour Day, celebrating this century old classic cocktail first mentioned in a Wisconsin newspaper in 1870. It’s a classic cocktail combining bourbon whiskey, lemon juice, simple syrup and egg white. The lemon in this cocktail rounds off the cocktail and gives it a sharpness. It’s simple and sophisticated.
