The Whiskey Sour is a classic and timeless cocktail that combines the richness of whiskey with the tartness of fresh lemon juice and the sweetness of simple syrup. It’s a versatile drink that can be made with either bourbon or rye whiskey, depending on your preference. The addition of egg white, although optional, adds a silky texture and a frothy foam to the cocktail. The garnish of a lemon wheel or cherry provides a visual touch to the drink.
