A raw-herring salad that is one of Phu Quoc island's signature dishes. Thin fillets of fresh herring are "cooked" in lime juice and vinegar, then tossed with toasted shredded coconut, fried shallot, and roasted peanuts. Diners wrap the dressed fish in rice paper with lettuce and herbs and dip it in a roasted-peanut and fish-sauce sauce, so each bite balances sour fish, sweet coconut, and savory dip.
Goi ca trich is closely tied to Phu Quoc, where herring is one of the most abundant inshore catches and also the fish used for the island's famous fish sauce. The salad is a fisherman's dish in origin — a way to eat the freshest herring straight off the boat without cooking, relying on lime and vinegar to firm and "cure" the flesh, with toasted island coconut to enrich it. It has no single recorded inventor and is best understood as a regional home-and-stall preparation rather than a dated creation; tourism has since made it the dish most associated with Phu Quoc's table.
The herring is firm and just-set rather than raw-slippery — the acid has tightened it without cooking out the clean sea flavor. Toasted coconut brings a sweet, slightly oily crunch that plays against the sourness; fried shallot and peanut add a roasted bass note. Wrapped in rice paper with cool lettuce and herbs, then dipped, each roll lands sour-fresh up front, then sweet and nutty, then salty from the dip. The freshness of the fish is everything; a day-old herring turns the whole plate fishy.
The lime juice and vinegar denature the herring's surface proteins, firming the flesh and muting its raw texture — the same acid-cure logic as ceviche, done quickly so the fish stays translucent at the center rather than going chalky. The toasted coconut does double work: its fat coats the acidic fish and rounds the sourness, while the toasting adds aroma the raw fish lacks. The peanut dip is thickened with ground roasted peanuts and balanced with fish sauce and sugar, giving each acidic bite a fatty, savory landing pad.
Variations
The Phu Quoc standard uses herring with toasted coconut and a peanut dip; some cooks add green-mango shreds or banana-flower for extra crunch and tartness. A few stalls press the herring with shallot and ginger as well. Mainland imitations sometimes substitute other small silver fish when herring isn't fresh, but islanders insist that the dish is defined by genuinely fresh herring and island coconut.

- 112 min
Fillet fresh herring, remove bones, and slice thinly.
- 28 min
Marinate the slices in lime juice and a little vinegar until the flesh turns firm and opaque at the edges, then drain.
Watch outMarinate in lime and vinegar just until the flesh firms and turns opaque at the edges — the acid is curing it like ceviche; leave it too long and it goes chalky-white through.
- 35 min
Toast shredded coconut meat in a dry pan until fragrant and lightly golden.
Watch outToast the shredded coconut in a dry pan until fragrant and lightly golden — this adds the aroma raw fish lacks; stop before it darkens or it turns bitter.
- 46 min
Pound roasted peanuts with fish sauce, sugar, garlic, and chili into a thick dipping sauce.
- 53 min
Toss the drained fish with the toasted coconut, fried shallot, and a handful of chopped peanuts.
