A citrus and sour whiskey cocktail ∙ Dry shake ∙ 5 min ∙ 15.6% ABV ∙
The Caramel Whiskey Sour is a bourbon sour sweetened with caramel syrup, shaken with lemon juice and egg white and served over ice.
The Caramel Whiskey Sour is a modern riff on the Whiskey Sour. It keeps the whiskey, citrus, and sweetener structure but swaps in caramel syrup as the sweetener, giving the sour a darker, toffee-like sweetness.
The earliest known printed mention of the Whiskey Sour dates to 1826, and no single creator is credited.
60 ml bourbon, 30 ml fresh lemon juice, 20 ml caramel syrup and 15 ml pasteurized egg white. Three dashes of Angostura bitters and two of saline solution are optional; they keep the caramel from tasting too sweet against the lemon.
It is a common rule of thumb: 3 parts whiskey to 2 parts lemon juice to 1 part sweetener. This recipe runs 60 ml bourbon, 30 ml lemon juice, and 20 ml caramel syrup, closer to 3:1.5:1, with a little egg white for texture.
Bourbon, which is what this recipe uses; its sweetness and vanilla notes suit the lemon and, here, the caramel. A spicier rye also works but makes the drink drier and sharper.
Shaken twice. First shake with ice to chill and dilute, strain the ice out, then shake again without ice to whip the egg white into foam. Fine-strain over fresh ice.
An old-fashioned glass, over ice, garnished with a lemon twist.
