.75oz VSOP Cognac

Add the cognac, rum, cointreau and lemon juice to a shaker glass. Add ice and shake vigorously until chilled. Strain into a chilled cocktail glass.
Heavier than the Sidecar but nearly as smooth, Between the Sheets is a tad sweeter due to the addition of rum, although lacking something that makes the Sidecar so great. A popular twist on the Sidecar, but if forced to choose, I tend to prefer the Sidecar.
Most sources credit this Sidecar variant to Harry McElhone of Harry’s NY Bar in Paris in the 1930s; however, there are other claims to its origin, non of which I can definitively substantiate. McElhone’s recipe supposedly replaced part of the cognac with light rum to make the cocktail a little lighter; however, many recipes call for dark/aged rum.
Both aged and light rum are good in Between the Sheets, but very different, with the dark rum leading to a heavier richer taste, while the light rum will lighten the drink and be less powerful. Try it both ways to see which style you prefer.
