The Southside is a fantastic cocktail to exhibit the transformative power of mint. At its heart it’s basically a fresh gin gimlet with some mint in the shaker. Its origins can most likely be traced to the Southside Sportsman’s club, a toney gentlemen’s club operating on Long Island in the 1860s. The club was famous for its juleps and soon started turning out variations, including its now eponymous cocktail. —Erik Lombardo

Shake all ingredients with ice and strain into a cocktail glass. For a variation, add 2 wheels of cucumber to the shaker and you have an Eastside, or serve tall in an ice-filled hiball topped with soda for an Eastside or Southside Rickey.
