Tongan raw fish ceviche: fresh sashimi-grade tuna or snapper cubed and briefly cured in lime juice, then dressed in coconut milk with onion, chili, and salt. Simpler than the Samoan or Tahitian versions — Tongan 'ota ika is essentially fish + lime + coconut + salt + onion, with chili added at the table.
'Ota ika is the universal Tongan everyday fish dish — sold at every market, made in every household. The simplicity is intentional: Tongan cooking emphasizes fresh ingredients in clean preparations. Unlike Fijian kokoda which includes tomato and cucumber, 'ota ika keeps the focus on the fish itself. Sold in coconut-shell cups at Talamahu Market in Nuku'alofa.
Spoon up 'ota ika — pearly tuna cubes coated in creamy coconut, lime-bright, gently salty. Simpler than Samoan or Fijian variants; the fish flavor dominates. Optional chili adds slow heat. Cooling, clean, Tongan.
Lime acid (pH 2.5) denatures fish surface proteins; coconut milk fat coats and emulsifies. Brief 5-8 min cure is critical — the Tongan preference is for the fish to retain its raw center.
Variations
Octopus 'ota ika uses cooked octopus. Mixed 'ota ika uses several fish. Spicy version doubles chili.

Watch the clock, not just the color — a 5-8 minute lime cure is the whole point; the Tongan way keeps the center of the fish raw, so pull it while it's still translucent inside.
