Poisson cru is a Tahitian national dish that consists of raw tuna, lime juice, various vegetables, and coconut milk. It is also known as ia ota or e'ia ota, which means raw fish. The dish is prepared by briefly marinating tuna in lime juice, and then coconut milk is added to mellow its acidity.

For a more authentic dish, fresh coconut meat is wrapped in cloth, and the milky juice is then squeezed over the fish and vegetables. Poisson cru is sweet, refreshing, and exotic, and can be found almost anywhere in Tahiti.
