Today is National Drink Watermelon Day, or is it National watermelon drink day? Either way I am celebrating.
I happened to have two watermelons in my kitchen and I knew exactly what I wanted to make. 'Otai. It's a delicious and really EASY to make Tongan watermelon drink.

'Otai recipe history:
'Otai originates from Tonga. A small Polynesian island chain in the south pacific. The kingdom of Tonga has over 170 islands but most are too small to inhabit, approximately 36-52 are inhabited (depending on which source is reporting this status) and 70% of Tongans live on the main island of Tongatapu. It is two thirds of the way from Hawaii to New Zealand.
So really, smack dab in the middle of the south pacific, south of Samoa, another gorgeous island nation I would love to visit one day. 
Tongan cuisine:
The cuisine in Tonga is lots of tropical fruits and vegetables like taro, bananas, yams, coconut and lots of fish and seafood. Western culture introduced citrus such as limes and lemons and watermelon soon became a favorite amongst Tongans. And I can see why.
A hot day on a tropical island, watermelon is most definitely a welcome refreshing treat especially when made into a watermelon drink.
What is 'Otai?
I first tried 'Otai in Hawaii about 15 years ago. I used to race Hawaiian outrigger canoes in California and a friend on my team was from Oahu and she invited me to come over one summer and race with her team, Lanikai outrigger. I got to go over and practice and race a couple of the sprint races for a small part of their regatta season. Her Hawaiian mom made us 'Otai after practices, a recipe she had learned from a Tongan friend.
'Otai is a watermelmon based drink, almost like a smoothie often made with other tropical fruit such as pineapple, mango, coconut etc. It is thick and creamy and super refreshing. It can be blended until very smooth and strained or blended with chunks of fruit left in it.
Ingredients needed:
- Watermelon - preferably seedless
- coconut milk
- coconut water
- lime juice
- simple syrup
- pineapple chunks or crushed pineapple ( can also use mango)
How to make 'Otai:
- Prepare the watermelon by cutting off the rinds
- Make sure all ingredients are super cold
- You can either make as described in the recipe which is the traditional method or make in a blender
This is amazing as is or blended fully for a smoother textured drink. I made popsicles with the leftovers since the recipe makes a lot. 'Otai is so delicious in both beverage and popsicle form.
Other versions:
There are many versions of Tongan 'Otai. This is the version we made in Hawaii all those years ago. Traditional 'Otai is much thicker, the chunks of fruit eaten with a spoon. Some recipes are made with evaporated milk, some with coconut milk. There are many ways to make it, and many people have their own adaptation or version of it. This is mine. Enjoy.
'Otai - Tongan Watermelon Drink
Ingredients
- 5-6 cups cold seedless watermelon cubed
- 1 cup cold crushed pineapple
- 1 can cold full fat coconut milk (approx 13.5 ounces)
- 1 cup cold coconut water
- 2 Tablespoons lime juice
- 2-3 teaspoons simple syrup - optional - see notes* or to taste if a sweeter drink is desired
Instructions
Traditional method:
- Place watermelon in a large bowl and mash or grate until mostly liquid but still some small chunks remain. Add in the rest of the ingredients except simple syrup and mash a little more, stir well. Taste and add simple syrup if a more sweet drink is desired then chill 30 min then serve over ice
- My way. The lazy way. Add all the ingredients except simple syrup to a blender ad pulse until blended but still chunky - you don’t want a thin puree. This drink has texture to it. Taste and add in some simple syrup and pulse for a few more seconds taste again and add more sweetener if desired. Chill for about 30 min then serve over ice.

losaline says
honestly when i read this i see u have changed the polynesian tongan otai drink to be sutied to you when this is not how the otai is made go to tonga and see how its made we dont want a palagi otai we want the home roots of tonga recipe whatever ur putting in this is not how u make otai
Shanna says
There are many versions of 'Otai. Yes this is my version, yes it is one of the many versions of it. My version is very close to the original. There is no need to be rude.
Kata says
You are right Shanna, you prepared it according to what is available in your place. You are acknowledge that watermelon and coconut is tradition. Do not be surprised that coconut is substitute with cream in Tonga because coconut is fading and very expensive. Just saying to keep it up
Shanna says
Thank you. I have an incredible amount of respect and admiration of Polynesian cultures and I never try to claim anything as my own. Its either my version or adaptation of a recipe or cited from the source. I love to share my versions of recipes and hope that people make mine, make their own versions of mine or seek out the most authentic version if they like. I do as much research into cultural recipes as I can before posting them and write about the history of the recipe as well.
Karma says
What the rudeness. Hoi. I have my own version and I’m scared to post it.
Shanna says
Right? If you don't have anything nice to say.... I guess yell at food bloggers online anyway? LOL.. Post yours! I don't think there is an issue with making one's own version of any recipe. Adaptations are what make recipes more interesting.
Fehi says
Dang losaline. Why don’t you share your recipe then
Shanna says
I welcome any commenter to leave their version so I can add it to my notes with credit. I am all for learning all the variations of cultural recipes and sharing them.
June Sione says
losaline PLEASE!! if you were in Shanna's shoes you will feel the same... GOSH!!!
Karma says
I’m going to add vanilla ice cream to my version and she if I get criticized?
Shanna says
I know I definitely wouldn't criticize, that sounds awesome!
Danielle says
She said there are many versions and this was her take/sound in it. How about you try it first, that’s the beauty of recipes you can keep the main idea yet recreate.could you imagine that there was only 1 recipe for any food, boring. Try it before making such a comment, rude.
Shanna says
Thank you for your kind comment. Adaptations to recipes is what makes for many more amazing recipes. I think she skipped the part where I gave credit to Tonga first, respecting the culture who originated the recipe.
Malu says
Just be happy that people of other races want to make our Tongan 'otai. Times have changed and recipes have changed too. Think outside the box you dinosaur! Thank you Shanna, l feel humbled and honored that you featured this dessert drink into your recipe book. Please don't mind this lady, her husband probably left her and now she's turned into a Karen. "Let me speak to your manager, l don't like this version of 'otai".....lol. Blessings to you Shanna ?
Shanna says
Thank you for your kind words.
PRAinAZ says
Thank you for this recipe! I was looking for a drink to use up some watermelon that was getting a mushy texture. I didn't have very much, so I only did a fourth of the recipe. I didnt have the coconut items so I used 3 oz Coco Real cream of coconut. Since it's sweet already, I didn't add simple syrup. I added some ice and blended it up into one great slushy. Had just enough to share with my hubby, 16 oz. We love it. Can't wait to make the real thing.
Shanna says
Yay I am so glad you like it!
Maile says
I see the recipe is changed from how the way it is originally is but I think that's really cool you tried it out, this is an amazing recipe for those who like it this way or the other too, you are awesome!!
Shanna says
Thank you so much!

Malo e Lelei Shanna,
I just made ‘otai this evening for friends visiting from Santa Cruz, California. It is summer and the perfect time for refreshing drinks.
I would love to try your recipe with lime juice. It sounds delicious. I enjoyed reading your post and educating readers about Tonga. Thank you for sharing our culture with others. How unfortunate that our “Friendly Islander” sister, Losaline, was not appreciative of your post. Perhaps your recipe may have best hers. Nonetheless, “I die, you die, we all die, for ‘otai”
‘Ofa atu,
Shanna says
Thank you so much. I really try my best to honor the cultures who's recipes I make or adapt, always give context and credit and my own personal experience with them. I really appreciate your comment! I think the recipe with lime juice sounds so good, I will have to try that soon too. Let me know how it comes out!
