Lest you think composers only expend their creative energies on boring old music, here's a concoction for the weekend (name courtesy of my Shakespeare-loving wife).
2 oz. gin
2 oz. tart cherry juice
1/2 oz. kirschwasser
1/2 oz. cassis
Shake with cracked ice and strain into a large martini glass.
While you drink, treat youself to the thermonuclear Shirley Verrett as Shakespeare's darkest lady of all (via Verdi).
