Try the national dish of Tahiti famous as "poisson cru" ("ia ota"). Every restaurant of Tahiti offers this dish. Locals cook it with fresh fish marinated in lime juice and coconut milk. Usually, Tahitians use fresh tuna or mahi-mahi. You can eat Poisson Cru immediately after preparation. But it is tastier after some hours when the ingredients' flavours have mixed. Coconut milk will soften its flavour and make it richer. The tuna fishing season lasts from May to September, so it's the best time for this dish.
