Stir with ice, strain into a cocktail coupe, and garnish with a grapefruit twist.
I was inspired enough by the combination of rabarbaro and Pedro Ximenez in the Cold Was the Ground (that I found on Kindred Cocktails) to riff on it. I swapped the spirits for the rye-mezcal duo that has worked in drinks like the My Old Piano and the Intrepid and the bitters for Angostura. I also upped the sherry to the half ounce that I thought would work better the night before. For a name, I kept the musical theme and became inspired by Nick Cave, so I called this one Slowly Goes the Night.
