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!
-
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.
