The Between the Sheets is a shaken sour that splits its base evenly between white rum, Cognac, and triple sec, cut with fresh lemon. Bright citrus hits first, then the rum and Cognac warm the middle before a clean, orange-tinged finish — a bracing after-dinner pour.
Between the Sheets belongs to the same family of split-base sours as the Sidecar, and its documented origin is disputed among a few competing accounts. The most repeated version credits Scottish-born bartender Harry MacElhone, owner of Harry's New York Bar in Paris, with creating it in the 1930s as a rum-added twist on the Sidecar. A rival account places its invention nearly a decade earlier, around 1921, at London's Berkeley Hotel, credited to a manager known as Mr. Polly. A third, less-substantiated story claims the drink originated in French brothels as a pre-shift drink for sex workers, which some link to its suggestive name, though this is the least documented of the theories. In print, the earliest known appearance is in Frank Shay's 1929 book Drawn from the Wood, though that version was made with gin rather than cognac and rum. By the 1930s, recipes using cognac, white rum, and triple sec, close to the version popularized at Harry's New York Bar, had become the standard, gaining wider circulation through Harry Craddock's 1930 Savoy Cocktail Book.
White rum, Cognac, and triple sec in equal measure, sharpened with fresh lemon juice and a touch of sugar syrup, shaken and served up. This build also carries a couple of dashes of saline solution to round out the citrus.
Three spirits: white rum, Cognac, and triple sec, an orange liqueur, all in equal parts. That three-spirit base is what gives the drink its 27.5% ABV, making it noticeably stronger than a typical citrus sour.
Yes, at around 27.5% ABV it is a strong cocktail, well above most shaken sours. The strength comes from stacking three full-proof spirits — rum, Cognac, and triple sec — rather than relying on a single base spirit cut with citrus.
Shake white rum, Cognac, triple sec, fresh lemon juice, and sugar syrup hard with ice, then fine-strain into a chilled coupe glass and garnish with a lemon twist. The shake is essential here — it aerates and chills the three-spirit base and folds in the citrus before straining leaves the glass clear.
