In a sturdy glass, muddle the strawberries, lime wedges, mint leaves, and sugar together using a muddler or the back of a spoon. This helps release the flavors from the fruit and mint.
Add Ice and Rum:
Fill the glass with ice cubes.
Pour the white rum over the ice.
Top with Club Soda:
Top off the glass with club soda and stir gently to combine.
Garnish:
Garnish with additional strawberry slices and a sprig of fresh mint.
