Cointreau Week of the Dale/David project continues tonight with the Between The Sheets Cocktail.
Okay--who knew that this drink wasn't invented on Sixth Street, at a bar where bouncers stand outside and holler "Two dollar Long Islands! Three dollar Jager bombs! Ladies first drink free", where they also pour shots like Red Headed Sluts and Cum in a Hot Tub?
Not me.

The Between the Sheets is a kissing cousin of the Sidecar

This drink, as it happens, has its origins in the Prohibition Era, when, according to David Wondrich, "the nation's moral fiber wasn't what it out to have been. But then again, neither was the nation's liquor supply." Traditionally the drink is made with cognac or brandy, rum, Cointreau, and lemon juice. According to Simon Difford in Cocktails, this drink was "created in the 1930's by Harry MacElhone of Harry's New York Bar in Paris." It is a descendant of the Sidecar, though is oddly formulated with two base spirits.

Dale addresses this idiosyncrasy by substituting Bénédictine for rum. He writes, "There are other versions that omit Bénédictine and use rum instead, but two base spirits can confuse the palate; this version is more interesting." It seems like this version is the less common one, since the first five books I pulled from the shelf offer the Cognac/Rum version. Nonetheless, I agree with DDG that this an interesting, and delicious, refreshment.
