Whiskey Sour
A whiskey sour is a mixed drink or shot containing whiskey , lemon juice, and sugar (Simple Sugar), and traditionally garnished with a cherry or sometimes a lemon wedge. It is a blend of sour, bitter, and sweet flavors. It can be made as a shot or mixed drink, either choice with a base spirit (whiskey or bourbon), citrus juice (lemon juice or sweet & sour mix), and a sweetener (Simple Sugar). Sometimes, an egg white is included, which is sometimes called a Boston sour. When the whiskey used is a Scotch, it is called a Scotch sour. With a few bar spoons of full-bodied red wine floated on top, it is usually referred to as a New York sour. It is shaken and served either straight up or over ice. The International Bartenders Association recipe includes a garnish of half an orange slice and a maraschino cherry.
