Cook Islands Ika Mata Recipe (Traditional Raw Fish Dish)
What is Ika Mata?
Ika Mata is the Cook Islands’ iconic raw fish dish, made with fresh fish, lime juice, coconut cream, and crisp vegetables. This traditional recipe is refreshing, simple, and deeply rooted in island culture.
This deliciously refreshing island dish packs so much South Pacific flavour it’s impossible to miss! Every bite sends you right back to golden sands and lazy palm trees on some remote island atoll with turquoise blue lagoons. And if you haven’t been to the South Pacific, a bite of Ika Mata can get you pretty close - Coconut, lime, fresh fish, veggies, even some fruit, these ingredients are truly enjoyable. And the best thing about this dish though, is that you can make it any way you want - adjust the ingredients, and make it your own!
I first learned about this dish as a young boy surrounded by family members who were from the island of Rarotonga. This dish, usually prepared by my Aunty Jean or my Grandma Rere, was at every family gathering, and for good reason! It was easy to make! It was delicious! And it gave all of the family members a tasteful and nostalgic way to reconnect to their island home.
How Ika Mata is made.
Fresh raw fish is cut up into small cubes. Usually, a white meat fish like marlin or Wahoo is used, but ahi (tuna) works just as fine. Once the fish is cubed, fresh lime or lemon juice is squeezed over the meat. 1-2 limes for every pound of fish is enough. After all the juice is squeezed out, toss the meat around in the bowl to coat all sides of the fish cubes in the citrus juice. This will ensure even “cooking”. Let the bowl stand in the refrigerator for 30 minutes to an hour, or until the meat flashes white all around. The meat is not really “cooking”. This process is a chemical process where the citric acid in the lime juice causes the proteins in the fish to firm up and turn opaque. It's important to know that the meat is still considered “raw” as the citrus juice does not kill bacteria or parasites the same way that cooking with heat does. But enough of that. This dish is delicious and I would eat it all day long!
Ok. Now that that's out of the way. Season the fish. Salt the fish with hawaiian salt if you have it, but any salt should be fine. I tend to make my saltings on the heavier side. It’s a nice way to bring out all the flavours against the strong citrus flavour.
Allow the salted fish, covered in lime juice, to sit in the refrigerator for about 30-60 minutes.
While you are waiting for the fish to “flash over”, begin chopping the vegetables. Dice up half a red onion, carrots, bell peppers, tomatoes, and cucumber. Here’s where your imagination and preference shape the dish. Experiment with different vegetables, herbs, and even fruits!
I like to keep mine simple. Everything above is all I need to enjoy this delicious dish. Once all the items are chopped up, add them to the bowl of raw fish and lime juice. Some people will say to drain the lime juice before adding the vegetables, but I leave mine in! Mix well.
When your bowl is filled and mixed well, add some refreshing, smooth coconut cream, covering the entire mix. You can use coconut milk if you do not have cream, but trust me, you’ll want the cream!
That’s everything! Serve chilled and enjoy! And as they say in Rarotonga…Ka Kite! (See you later!)

Ingredients for Ika Mata
2–3 lbs - raw fish (ahi, marlin, or ono), cubed small
2–3 heavy pinches Hawaiian salt
½ red onion, diced
1–2 cucumbers, peeled and chopped
1 handful cherry tomatoes, quartered
5–6 lemons or limes (enough juice to fully cover fish)

How to Make Ika Mata (Step‑by‑Step)
1 Season the fish. Place the cubed raw fish into a bowl and season generously with Hawaiian salt. Mix well so every piece is coated.
2 Cure in citrus. Squeeze the lemons or limes over the fish until it is fully submerged. Stir and let it sit in the refrigerator for 10–15 minutes to an hour until the fish turns white on the outside.
3 Add vegetables. Drain off most of the citrus (leave a little for brightness). Add diced red onion, chopped cucumber, and cherry tomatoes. Mix gently.
4 Add coconut cream. Pour in 1–2 cans of coconut cream depending on how creamy you like it. Stir to combine until the fish and vegetables are fully coated.
5 Taste and adjust. Add more salt, citrus, or coconut cream to taste. Chill before serving for the best flavor.
Note: You can add other vegetables or ginger for added flavors. There's no wrong way to make this dish! ENJOY!
