The Whiskey Sour cocktail is a classic drink with a whiskey base. An unusual twist with this drink is the optional dash of egg white, however, can be substituted for pineapple juice if you do not like or cannot have eggs. This drink is served either in a cocktail glass or if served “on the rocks”, then an old fashioned glass should be used instead. Traditionally a whiskey sour is garnished with half a slice of orange and a cocktail cherry.
