Poisson Cru (Tahitian Raw Fish in Coconut Milk and Lime)

Origin

Poisson cru (French: "raw fish") is the national dish of French Polynesia — fresh tuna marinated in lime juice and dressed in coconut milk with tomato, cucumber, onion, and carrot. The French name is retained because French is the colonial and administrative language of French Polynesia, and the dish is known worldwide by this name. The Tahitian name is i'a ota (raw fish). Poisson cru is the most internationally recognised preparation on the Pacific raw-fish thread, partly because of French Polynesia's status as a tourist destination and partly because the dish has been adopted by French-influenced restaurants globally. It sits on the same thread as Samoan oka (WS-2), Tongan 'ota ika (TO-3), Fijian kokoda (FJ-2), and Cook Islands ika mata (CK-2) — acid-denatured fish dressed in coconut fat — but with a specific Tahitian distinction: poisson cru uses coconut milk (thinner, less fat) rather than coconut cream (thicker, higher fat), producing a lighter, more liquid dish. Oliver documents poisson cru as "the gateway dish of Pacific cuisine for non-Pacific visitors" (Me'a Kai, 2010).

Description

Fresh yellowfin tuna (Thunnus albacares, the prestige species — Tahiti sits in one of the world's richest tuna-fishing grounds) is filleted and cut into 1–1.5 cm cubes. The cubes are placed in a bowl and covered with fresh lime juice (not lemon — lime is the Tahitian standard). Marination: 15–30 minutes, until the surface turns opaque. The lime juice is not drained — this is a key Tahitian distinction from the Samoan and Fijian versions, where the acid is partially or fully drained. Coconut milk (not cream — the Tahitian version uses second-pressing coconut, which is thinner and less fatty) is added directly to the lime-fish mixture. Diced tomato, diced cucumber, finely sliced onion, grated carrot (a Tahitian addition not found elsewhere on the thread), and salt are folded through. The dish is served immediately, in a bowl, with the lime-coconut liquid serving as a drinkable sauce. The French colonial influence is visible in the plating: poisson cru is served in glass bowls rather than coconut shells, and the garnish is more finely cut than in Samoan or Tongan versions.

The Thread

• PH-1 (kinilaw) → FJ-2 (kokoda) → WS-2 (oka) → TO-3 ('ota ika) → CK-2 (ika mata) → TP-1 (poisson cru) → HI-4 (poke) → NZ-2 (kaimoana). Poisson cru is the lightest, most acidic expression on the central

Flavour Context

Poisson cru has a bright, citric, light flavour profile — the most acidic of the Pacific raw-fish preparations. The lime juice, retained in the dish, provides a sharp, sustained acidity. The coconut milk adds a moderate sweetness and light fat — enough to round the acid without dominating it. The tomato adds a gentle acidity and sweetness. The grated carrot adds a subtle sweetness and orange colour that is visually distinctive. The tuna contributes a clean, meaty baseline. Species precision: yellowfin tuna (Thunnus albacares) is the standard. Bigeye tuna (Thunnus obesus) is acceptable. Reef fish can be used but produce a milder, less assertive dish. The overall profile: bright acid, moderate coconut fat, clean tuna, fresh vegetable. This is a refreshing dish, not a rich one — the opposite end of the spectrum from Tongan 'ota ika.

Key Principles

Raw-fish thread: TW-1 (silaw) → PH-1 (kinilaw) → FJ-2 (kokoda) → WS-2 (oka) → TO-3 ('ota ika) → CK-2 (ika mata) → TP-1 (poisson cru) → HI-4 (poke) → NZ-2 (kaimoana). Poisson cru is the lightest, most acidic expression on the central Pacific segment of this thread. Where kokoda and 'ota ika are rich and cream-heavy, poisson cru is bright and citric — the lime juice remains in the dish, the coconut is milk rather than cream. This makes poisson cru closer in spirit to Latin American ceviche (acid-forward, light) than to the cream-forward Polynesian preparations. The dish also connects to the French colonial thread: the name, the plating, and the grated carrot (a French aromatic addition) reflect two centuries of French culinary influence on Tahitian food. → Related: WS-2, TO-3, FJ-2, CK-2, HI-4, NZ-2, TW-1, PH-1

Pro Tips

Poisson cru lives or dies on the balance between acid and fat. Because the lime juice is not drained, the coconut milk must be added in sufficient quantity to balance the acidity — too little milk produces an aggressively sour dish that overwhelms the fish. Too much milk dilutes the lime and produces a bland, watery preparation. The correct ratio is approximately equal volumes of retained lime juice and coconut milk. The second pivot: the tuna grade. Because the flavour profile is light and the sauce is thin, any deficiency in the fish (age, freezer burn, ammonia) is immediately detectable — there is nowhere for a flawed fish to hide in poisson cru.
