Prepare the mango (only if using fresh): Peel and chop ½ cup fresh mango and blitz in a blender until smooth. Strain for a silky texture if you prefer.
Muddle the mint: Add 8–10 mint leaves and 2 tbsp lemon juice to one glass. Gently muddle for about 10 seconds to release oils. Don’t pulverize the mint — bruise it.
Add mango nectar: Pour ½ cup mango nectar into the glass. If using puree, add that instead.
Top with soda and ice: Add ½ cup club soda, top the glass with ice cubes, and stir gently to combine.
Garnish and serve: Add a lime wheel and a sprig of mint on top. Enjoy immediately.
Repeat for the second glass and cheers! Want it stronger? Add a splash of white rum (but that, my friend, turns it into a cocktail).
