In a cocktail shaker, muddle about 4 fresh mint leaves then add ice, pineapple juice, rum and powdered sugar. Shake gently then strain into 2 cocktail glasses filled with fresh ice.
Top the drink with a splash of club soda to taste, stirring gently.
Garnish with a sprig of fresh mint and enjoy!
Notes
Despite the addition of powdered sugar, this drink isn’t that sweet. If you prefer to have your cocktails a little more aromatic, swap the club soda for lemon-lime soda.
