Why we love this recipe

This was a recipe that we were both really looking forward to, and for good reason.

When we first came across it, poisson cru struck us as a rich and vibrant ahi tuna salad with an added twist of coconut milk.

Really… who wouldn’t want to try a recipe mixing tastes of raw (okay, slightly ceviche “cooked”) fish, fresh vegetables and smooth coconut milk?

We were hooked from the start.

Tahiti and its Poisson Cru

Well-known as a luxurious tourist destination and for its beautiful weather, Tahiti is one of the largest and most recognizable islands in French Polynesia, itself a set of 118 separate islands (wow!) closely clustered together in the Pacific Ocean. The French Polynesian islands are considered to be one of the last places on Earth to have become inhabited with humans, with the first settlers coming only a few thousand years ago.

These islands came into contact with European colonists – from the Portuguese to the British to the French – before ultimately being annexed as a French colony in 1880. Today, Tahiti and the rest of these islands are French territories with completely civil and political rights as mainland French citizens, and the official language spoken is recognized as French.

However you’d like to call it, poisson cru will be as close to a Tahitian national dish as you’ll get. Eating establishments of all shapes and sizes, from the roulettes food carts to the to-go aisles of supermarkets to the fine dining restaurants, will most likely have some version of poisson cru available on their menus.

About the Recipe

One thing that’s really inspiring about Tahitian cuisine is how each recipe yields such exquisite tastes from ingredients that are readily available and abundant throughout the land. It seems as close to this notion of “sustainable eating” as you’ll get.

Mixing vegetables in a large clear bowl

Poisson cru is certainly no exception. It is an incredibly simple recipe that highlights the traditional ingredients common to most Tahitian recipes.

At the heart of the recipe is raw fish, hence giving the poisson cru recipe its namesake. Technically, the name suggests that any type of local and raw fish can be used, although most recipes that we came across used raw sushi-grade tuna.

Much in the same way ceviche is prepared in South American countries, the raw fish will “cook” slightly in a marinade of citrus juice and salt. In this type of preparation, there’s no real cooking with heat going on, but the citric acid from the citrus juices triggers the same denaturation processes to the meat’s proteins as heated cooking will do, if even for only a moment.

This type of cooking doesn’t take very long at all, and in fact it’s best that it doesn’t. Depending on the recipe, most anyone will advocate to “cook” your fish between only 10 and 20 minutes maximum, else the citric acid “overcooks” the fish and makes it tough.

Besides the ceviched fish, this recipe is full of vibrantly colored and flavored vegetables, and then there’s the coconut milk. Once the raw fish and vegetables have been mixed together, you drizzle coconut milk and mix through to give a smooth flavor that beautifully counterbalances the tart flavor that comes from the citrus influence.

Our Take on the Recipe

Given the simplicity of the core poisson cru recipe, there is not all too many changes that we made to our original reference recipe.

When it came to sourcing our fish for this recipe (and we would really caution you to do the same as well), we were extra careful and made extra sure to make sure that we got the right type of quality fish that’s usable for raw consumption. While ceviche-style preparation will give a similar denaturation result to your fish’s proteins, it will not kill bacteria the way that heat cooking will.

For this reason, it’s really of the utmost importance to get fresh, preferably wild caught raw fish. Here in the US, the term sushi-grade usually denotes a reasonable quality, but the best way to be sure is to ask your fishmonger.

Adding tuna with the vegetables

For “cooking” our fish, we erred closer on the earlier side of cooking than the later side. This is more a personal preference of ours, but we’d rather prefer having slightly fuller and chewier pieces of fish rather than perhaps “overcooked” and tougher more tart pieces.

One particular tweak we really enjoyed doing was including some of the “cooking” lime juice into the final dish. Most recipes will drain all or most of the lime juice, but we found that adding back some of the lime juice which our tuna cooked in gave more balance to the taste.

Adding more lime to the vegetable and tuna mixture

Other than that, there is not all too much else that we changed to this fantastic recipe.

Fresh and mild while zesty and tart all at once, it’s the quintessential Polynesian recipe and a great window into Tahitian cuisine. Bonus points that it’s so incredibly fun and easy to make too!

  1. Heather,
    This dish is reminiscent of ahi poke, one of the staples of my sushi lunches when we lived in Hawaii. I like how different cultures will use similar ingredients and create totally different and very delicious meals.
    Thanks!
