Instructions
 

Prep Your Watermelon Like a Queen

  • First things first — cut your watermelon into cubes and pick out any seeds you spot.
  • Give it a little taste test (quality control is important!) and make sure it's sweet and juicy.
  • I usually cut extra because let's be real, you're gonna snack while you're making this!

Muddle Like a Gentle Goddess

  • In your glass, add the watermelon cubes and gently muddle them until they're all juicy and broken down.
  • Add your mint leaves and give them the gentlest muddle — we want to bruise them, not destroy them!
  • Add the lime juice and sugar, then muddle just a tiny bit more to combine everything.

Add the Fun Stuff

  • Pour in your rum and give everything a good stir.
  • Fill the glass with ice — be generous, we want this COLD!
  • The ice will help mix everything together and make it look all fancy and layered.

Top It Off With Fizz

  • Slowly pour in your club soda or sparkling water.
  • Give it one gentle stir — you don't want to lose all that beautiful fizz!
  • Taste and adjust — need more lime? More sweetness? More rum? You're the boss here!

Serve It With All the Style

  • Garnish with a fresh mint sprig (slap it between your hands first to release the oils).
  • Add a lime wedge and maybe a cute watermelon slice on the rim.
  • Pop in a fun straw and take that perfect Instagram pic!

Notes

  • Want it sweeter? Add extra simple syrup or muddle in a few watermelon chunks with sugar.
  • Making a pitcher? Multiply ingredients and muddle everything in a large jug. Wait to add soda water until serving so it stays fizzy!
  • No alcohol? Skip the rum and use more sparkling water — still super refreshing.
  • Not sweet enough? If your watermelon is bland, splash in pineapple juice or add a bit of honey to boost the flavor.
  • Slushy vibes? Toss everything in a blender with ice and blend until frozen — mojito slushie = summer magic.
  • Bougie garnish alert: A slice of watermelon on the rim and a slapped mint sprig take your presentation to the next level.
