This low-calorie Whiskey Sour is a bourbon sour made with a sugar-free sweetener syrup in place of simple syrup, double-shaken with lemon juice and egg white.
The Whiskey Sour (low-calorie) is a modern dietary twist on the classic Whiskey Sour, replacing sugar syrup with a sugar-free sweetener to cut calories; no creator or date is recorded for it.
The Whiskey Sour is one of the oldest named American cocktails. It appears in print as early as 1826, though no single creator, bar, or city is credited.
This version is, at about 120 calories per serving, because it replaces the usual simple syrup with a sugar-free sweetener syrup; the bourbon and egg white are unchanged.
Shake bourbon, lemon juice, sugar-free sweetener syrup, egg white and the optional bitters with ice, strain back into the shaker and shake again without ice. Fine-strain into an ice-filled old-fashioned glass and garnish with a lemon slice.
Use a sugar-free sweetener syrup in place of simple syrup, which is exactly the substitution this recipe makes; the bourbon, fresh lemon juice and egg white stay the same.
