Gently muddle the fruit and mint to release their flavors.
Add ice cubes to fill the glass halfway.
Pour in white rum.
Stir gently to combine all ingredients.
Top up the glass with club soda.
Garnish with extra raspberries and a sprig of mint.
Notes
I like using homemade simple syrup (equal parts sugar and water) for the freshest taste. If I’m craving something sweeter, I’ll add a little extra syrup.For a non-alcoholic version, I just skip the rum and add more soda and lime. Crushed ice chills it faster, but regular cubes work if that’s what you have.Fresh limes and mint are key—bottled lime juice or dried mint just doesn’t have the same punch. If raspberries aren’t in season, I’ll use frozen, but I let them thaw first so they muddle better.
