A classic whiskey sour is one of the easiest classic cocktails to master. Made with bourbon, fresh lemon juice, simple syrup, and the occasional egg white, the drink delivers a perfect balance of sweet, tart, and boozy. The best whiskey sour recipes hinge on freshly squeezed lemon juice and shaking the cocktail well with plenty of ice until thoroughly chilled. Serve over fresh ice with an orange wheel and a cocktail cherry for the classic finishing touch. Whiskey Sour FAQs
