1 oz of white rum (or Light Rum)
3 oz of Pineapple Juice
1 oz of campari bitters
campari-stained pineapple (or Pineapple)
Pour the white rum, campari and pinapple juice into a shaker over ice, stir so as not to froth up the cocktail until well blended. Strain into a martini glass and garnish with a campari-stained pineapple wedge on the rim.
