This smooth and frosty Tongan watermelon cooler is now my favorite fix for blazing hot afternoons. Juicy watermelon teams up with coconut and pineapple for a real splash of island flavor. Every batch feels like catching some sun right in my kitchen.
Refreshing Ingredients
- Granulated sugar to taste: sweetens everything up Taste first since sometimes the fruit does all the work
- Water: helps you get the drink as thick or thin as you want Add slowly until you like the texture
- Canned coconut milk: gives everything a creamy base so shake up that can before you pop it open
- Fresh shredded coconut: adds bite and a cozy coconut punch Use frozen if the fresh stuff’s hard to get
- Canned crushed pineapple with juice: brings a lively sweet-tart note Go for a can without extra syrup
- Seedless watermelon: shred it up for lots of juice and easy to drink Pick one that’s heavy with a creamy yellow spot on one side
Easy Instructions
- Chill and Serve:
- Wrap the bowl or move the drink to a pitcher and stick it in the fridge Let it get nice and cold Serve straight up or pour over crushed ice if you want extra frostiness
- Sweeten to Taste:
- Add your sugar bit by bit Stir and taste as you go since some watermelons make the drink sugary enough by themselves
- Adjust Consistency:
- Pour in up to three cups of water while mixing Try it as you go to see if it’s just how you like for sipping
- Combine the Fruits:
- Mix in the pineapple and its juice plus the coconut and coconut milk into your bowl of watermelon Give it a good stir so everything gets evenly spread out
- Prepare the Watermelon:
- Grab a fork or a grater with big holes and shred your watermelon over a roomy bowl Let all the sweet juice gather for top flavor and texture

Fresh coconut just makes this drink shine It adds chew and real-deal flavor I feel like I’m right back with my family giggling around the table with cold glasses dripping on our hands
Keeping It Fresh
Stick any extra in the fridge covered and drink within two days Give it a stir before your next round since the fruit wants to sink If you need to keep it longer skip the ice until you’re about to grab a glass so it stays tasty and not watered down
Swaps and Options
No fresh coconut No worries Grab dried shredded coconut soak in warm water and you’re set If you’re out of crushed pineapple blend up canned pineapple chunks instead
Fun Ways to Serve
Pour it over plenty of ice for that super chill effect or turn it into a cocktail mixer for summer nights Pop in a shot of lime or let a pineapple wedge float on top for a cheerful twist

Common Recipe Questions
- → What type of watermelon works best for Otai?
Seedless is awesome for easy grating and mixing, but honestly any watermelon that's juicy and ripe does the trick.
- → Can I substitute fresh pineapple for canned?
Totally, use fresh if you've got it. Toss in the juice too for extra flavor, or just bump up the sugar a little to strike a balance.
- → How do I shred watermelon for this drink?
Grab a fork, a melon baller, or any wide-toothed grater and pull it across the watermelon—you want small bits that still hold their juice.
- → Should Otai be served chilled?
Colder is better. Pop it in the fridge or load your glass with ice, then pour and enjoy that frosty goodness.
- → Is coconut milk essential?
Using coconut milk cranks up the creamy, tropical factor, but you can skip it or use less if that's not your thing.
- → How can I adjust the sweetness?
Stir in some sugar a bit at a time and taste until you hit your sweet spot. There's already natural sugar from the fruit, so don't overdo it.
