Muddle the Base: In your glass, muddle the lime wedges, mint leaves, and sugar gently just enough to release oils and juice, not shred the mint.
Add the Rum: Pour in the Malibu Coconut Rum over the muddled mix.
Fill with Ice: Add crushed ice or ice cubes to fill the glass almost to the top.
Top with Soda: Pour soda water over the mix until the glass is full.
Stir Gently: Use a bar spoon to give it a gentle stir, blending everything without killing the fizz.
Garnish & Serve: Add a lime wheel and a sprig of mint on top. Serve with a straw if desired.
