This silky chilled Tongan watermelon sipper is my absolute favorite when the heat is unbearable. Juicy watermelon shines with coconut and pineapple flavors and every batch tastes like a mini vacation right at home.
Dreamy Ingredients
- Seedless watermelon: run it through a grater or pull it apart with a fork for that burst of juice and smooth sipping Don’t forget—the heavier it is for its size, the better and a golden belly means it’s sweet
- Canned pineapple (crushed & juice): brings a zingy tropical sweet note Hunt for pure fruit and juice—skip any with syrup
- Fresh coconut (shredded): gives chew and sweet coconut vibes Got frozen Instead use it unsweetened
- Coconut milk (from a can): makes things creamy and smooth Pop the can and give it a shake before using
- Water: lets you pick if it’s thick and rich or a little lighter Just pour until it’s just right for you
- Granulated sugar (to your liking): brightens up the whole thing Only add a bit at first since ripe fruit might be sweet enough already
Easy Instructions
- Chill and Serve:
- Stick your finished mix in the fridge or pour it into a pitcher and chill it way down Serve super cold or drop in some crushed ice right at the end
- Sweeten to Taste:
- Add sugar little by little and try it as you go so you get it just right Some watermelons are plenty sweet on their own
- Adjust Consistency:
- Pour in two or three cups of water a bit at a time and stir Decide how thick or sippable you like it
- Combine the Fruits:
- Dump in pineapple plus all the juice coconut and coconut milk with your watermelon and stir it up Make sure the pineapple and coconut get all mixed throughout
- Prepare the Watermelon:
- Take your watermelon and shred it with a fork or grater (big holes work best) over a big bowl so all that good juice stays put You’ll get the freshest flavor this way

The best part for me is fresh coconut. It’s chewy and real, so it feels like the genuine Tonga deal Every sip makes me think of my family laughing and sweaty glasses on hot afternoons
Storing Leftovers
Pop leftovers in a sealed container and keep them in the fridge up to two days. Before you pour another glass, give it a good stir—fruit will settle down at the bottom If you want to save it even longer, wait to add any ice until you’re ready to drink so it stays nice and rich
Try These Swaps
No fresh coconut No worries. Use finely shredded dried coconut, but soften it quick in hot water. If your pantry is out of crushed pineapple, just grab canned chunks and give them a whirl in the blender
How To Serve
Pour it over crushed ice for a frosty lift or mix it up as a base for cocktails. Drop in a splash of lime or top with a pineapple chunk for something extra special

Why It Matters
In Tonga, Otai means summertime fun. Watermelon pineapple and coconut are the stars and every picnic or party gets better with a big batch of this. Families have their own tweaks depending on what’s in the kitchen
FAQs About the Recipe

If you can get a seedless one, that's the easiest to shred and mix—but honestly, any ripe, tasty watermelon will work fine.

Totally! Fresh pineapple is awesome, but canned works too. Just pour in the juice for extra sweetness, or toss in a little more sugar if you want.

Grab a fork, a melon baller, or a grater with big holes. Shred up the watermelon so you've got lots of juicy little bits.

Coconut milk brings out that soft, tropical vibe, but feel free to skip or add less if you want it lighter.

Just sprinkle in sugar a little at a time and keep tasting. Both pineapple and watermelon are naturally sweet, so go easy and adjust as you sip.
