What is goi ca mai in Phu Yen?
Goi ca mai is a Central Vietnamese raw fish salad made with mai fish — small, translucent fish cured in lime until the flesh turns opaque. Mixed with fresh herbs, sliced onion, chili, and crushed peanuts. Eaten with sesame rice crackers or plain rice. Costs 50,000–80,000 VND per serving at coastal market stalls.
Goi ca mai is one of those dishes that sounds simple and is difficult to reproduce. It’s raw fish — but the experience of eating it is nothing like what that phrase usually suggests.
What it is
Ca mai are small, slender fish common to the brackish coastal waters of central Vietnam — translucent white when raw, about 10–15 centimeters long. They’re caught daily by small boats close to shore and don’t keep well, which is why this dish is so localized.
The preparation is similar to ceviche: the fish are marinated in lime juice or rice vinegar for long enough that the acid firms the flesh and the flesh turns from translucent to opaque. This is a chemical process, not heat, but the result is fish that is no longer truly raw in the biological sense.
Once the fish is cured, it’s drained and mixed with:
- Fresh herbs (cilantro, Vietnamese perilla, mint)
- Sliced onion and scallion
- Fresh chili
- Crushed roasted peanuts
- Fish sauce and sugar
The mixture is served with sesame rice crackers (banh trang me) for wrapping, or plain steamed rice.
What it tastes like
Light and acidic. The mai fish has a mild, clean flavor — much less intense than sardines or anchovies. The marinade is the dominant note, balanced by the herbs and the crunch of peanuts. Nothing about it tastes heavy or fishy in the way Western eaters sometimes fear with raw fish preparations.
Where to eat it
The best goi ca mai in Tuy Hoa is served near the water, in the morning. The fishing pier area (cang Dong Tac, east of central Tuy Hoa) has stalls and small restaurants that receive fresh mai fish from the night’s catch. Cho Tuy Hoa market also has goi ca mai vendors operating from around 6am until late morning, when the fish is gone.
Away from these locations — at hotels or tourist-facing restaurants — the freshness drops and the dish loses most of its appeal.
Cost: 50,000–80,000 VND per serving at market stalls; slightly more at sit-down restaurants.
Practical notes
This is a morning dish. Afternoon availability is inconsistent. Go to the market or pier area before noon.
The dish requires fresh, same-day fish. Don’t order it from a restaurant that looks like it has slow turnover — the fresher the fish, the better the goi.
