Qigu Mullet Roe | Tainan Signature Dish

Every year around the winter solstice, mullet (called xin yu, or 'letter fish') follow the cold currents south from the north and gather off the coast of Qigu. Fishermen call them 'black gold.' The egg sacs are cut open, cured in coarse salt, laid flat on bamboo racks, and sun-dried for several days until the surface turns orange-red and translucent. Hold a thin slice up to the light and the fat distribution reveals itself clearly — this is the most labor-intensive, time-sensitive ingredient in Taiwan's New Year table.

What Is Qigu Mullet Roe

Mullet roe is made from the ovaries of mullet (scientific name Mugil cephalus), salt-cured and sun-dried. The process involves removing the egg sacs, washing away blood, curing in coarse salt, sun-drying with regular turning until the right dryness is reached, and the final product is an orange-red, elongated flat block. Qigu's mullet roe is known for being freshly sliced, freshly cured, and sun-dried on-site — quality that surpasses most imported roe, which is typically made from farmed, frozen egg sacs. To eat: cut into thin slices and pair with thin slices of white radish or garlic. It can be eaten as-is, accompanied by kaoliang liquor, or lightly pan-seared before eating.

Qigu is an important fishing port on the western coast of Tainan. During the mullet migration season (roughly mid-December to January), fresh-sliced mullet roe at the port is one of the area's most significant fishery products. Prices at Qigu port direct sales are roughly 60–70% of packaged retail prices — worth going to the source, though it's advisable to inquire about stall operating hours in advance. Qigu also hosts a Black-Faced Spoonbill Ecological Reserve, and the roe production season overlaps with the spoonbills' southward winter migration, making a combined itinerary easy to plan.

How to Eat It Like a Local

🥢

Thin Slices with White RadishThe most traditional way to eat mullet roe: cut on a diagonal into thin slices and eat together with thin slices of white radish. The sweet crunch of the radish cuts through the saltiness of the roe.

🍶

Kaoliang Is the Classic PairingAt Taiwanese New Year gatherings, mullet roe is commonly paired with kaoliang liquor. The alcohol volatilizes and draws out the fragrance of the roe fat — the classic combination at a Tainan fishing family's table.

Lightly Seared Works TooMullet roe can be placed on foil and lightly toasted over low heat, or dry pan-seared until the surface bubbles and slightly chars — crispier and more aromatic, good for those not accustomed to eating it straight.

⚖️

Check the Fat Distribution When ChoosingHold quality mullet roe up to light: the fat should be evenly distributed, the color orange-red and clear with no discolored patches. Ask the vendor to hold it to the light before you decide at a direct-sale stall.

Visitor Tips

Mullet roe is a popular New Year gift. Qigu port sees concentrated weekend crowds in winter — weekday visits are recommended, or call ahead to reserve and pick up.
Vacuum-sealed and refrigerated, it keeps for several weeks; frozen, it lasts several months. If carrying it for more than 4 hours, bring an ice pack.
Qigu pairs well with a half-day itinerary that includes the Black-Faced Spoonbill Ecological Reserve (the birds also migrate south around the same time) and the Qigu Salt Mountain.
