Quarantini
Garnish with real Maraschino cherry, inaccessibly located at bottom of glass.
Place all ingredients (withholding the optional simple syrup) in shaker with ice. Add simple syrup (or extra cherry juice from jar) for those that demand it. Pause and remember that, one day, quarantine will be over. Shake. Strain into chilled martini glass.
