Wikipedia: Whiskey sour
The whiskey sour is a mixed drink containing whiskey (often bourbon), lemon juice, sugar, and optionally, a dash of egg white. With the egg white, it is sometimes called a Boston Sour. With a few bar spoons of full-bodied red wine floated on top, it is often referred to as a New York Sour. It is shaken and served either straight up or over ice.
The traditional garnish is half an orange slice and a maraschino cherry.
How Well Do You Actually Know the Whiskey Sour?
With just three ingredients, the Whiskey Sour has enjoyed more than a century of unparalleled popularity. Here, the classic recipe and its modern interpretations.

The first printed record of the Whiskey Sour appears in 1862 in Jerry Thomas’ How to Mix Drinks, though the recipe likely dates back many years earlier. Relying on sugar to be dissolved in a small amount of water before adding the remaining ingredients, rather than syrup, the original Whiskey Sour construction resembles that of punch. But unlike punch, the Whiskey Sour has always been made on a small plan, a fact that makes it difficult to pinpoint the drink’s precise origins.
While the original three-ingredient cocktail is still the best-known version, other early renditions of the drink have since gone on to become classics in their own right, from the red wine-topped New York Sour to the frothy Boston Sour, made with egg white—a PUNCH favorite.
