POISSON CRU (TAHITIAN LIME-MARINATED TUNA AND COCONUT SALAD)
SOURCE: RAFAEL STEINBERG. PACIFIC AND SOUTHEAST ASIAN COOKING.
Its underlying culinary principle is simple chemistry — lime juice cooks the fish by protein denaturation, and coconut milk mollifies the astringent acidities that residually linger and bite into the taste buds. Despite its Francophonic name, which translates to “raw fish”, Poisson Cru has always kept and prided itself of its immaculately Tahitian identity and nationalism even under the territorial governance of France for more than 140 years. With the Polynesian archipelago halfway around the globe, the mainland French never bothered to appropriate the respective marinating and smothering of fish chunks in citrus juice and coconut milk into a bistro favorite, unlike the tartare of any finely minced animal flesh. In contrast, Poisson Cru comes to the table au naturel, that is, the fish, preferably tuna, must be the freshest among the day’s catch and the coconut is the most virginal at the first press. One can only expect a burst of indescribable deliciousness that leaves to be savored in order to be fully understood.
