Luscious Otai Watermelon Cooler

Category: Small Bites, Worldwide Flavors

‘Otai is the go-to summer sip from Tonga, jam-packed with juicy island flavors. You start with plenty of seedless watermelon, shredded up so it's all juicy and fresh. Throw in some crushed pineapple for a little zing and coconut for the creamy touch. Everything gets tossed together in a big bowl, then loosened up with water and coconut milk until it's just right. Stir in sugar to fit your sweet tooth. Serve it loaded with ice or straight-up cold for the ultimate refresher. This colorful drink is awesome at big get-togethers or when you need to cool off. Make it your own by tweaking the sugar or water to get it how you like.

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

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

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

FAQs About the Recipe

→ Which watermelon works best in Otai?

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

→ Can I use canned pineapple instead of fresh?

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.

→ How do I break down watermelon for Otai?

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.

→ Is it important for Otai to be cold?

Absolutely! It's best icy, right from the fridge or loaded with crushed ice. That's when it's the most refreshing.

→ Do I really need coconut milk?

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

→ How do I control how sweet it gets?

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.
