What is a "whiskey sour" made of?

A "whiskey sour" is a classic cocktail that is made with whiskey, fresh lemon juice, and simple syrup. This combination creates a balanced drink, where the rich, warm flavors of the whiskey are complemented by the tartness of the lemon juice and the sweetness of the simple syrup.

The whiskey provides a robust foundation, typically using bourbon or rye, while the lemon juice adds a refreshing acidity that brightens the drink. Simple syrup, which is a mixture of sugar and water, rounds out the flavors by providing sweetness. This trio of ingredients is shaken with ice and often served over ice in a rocks glass, sometimes garnished with a cherry or a slice of lemon.

Other options listed do not represent a whiskey sour. For instance, ingredients like gin, tonic, and lime are associated with a gin and tonic rather than a whiskey sour. Similarly, rum, cola, and citrus would suggest a different cocktail, such as a rum and coke. Lastly, vodka, olive juice, and vermouth relate to a martini or a dirty martini, which is also distinct from the whiskey sour. The specific combination of whiskey, lemon juice, and simple syrup is what defines this cocktail.
