In a cocktail shaker half-filled with ice, combine gin, cherry brandy and lime juice; shake. Strain into a cocktail glass almost filled with ice cubes. Drop the Benedictine and brandy into the center of the drink. Garnish with cherry and an orange slice.
A popular variation is the gin sling, which uses sweet vermouth instead of cherry brandy; a dash of bitters can also be added. Garnish with a twist of lemon.
