Tukuyu geng is a Penghu night-market soup of deep-fried fish slabs in thick broth, traditionally made with Spanish mackerel, though many stalls now substitute cheaper fish.
Penghu's Spanish mackerel (locally called "platinum tukuyu") is in season from roughly November through March or April, with the fish richest in fat and aroma between the winter solstice and the Lunar New Year when the water is coldest. However, genuine premium mackerel is expensive — a single fish can cost over NT$10,000 — and according to a Liberty Times report, most night-market versions of tukuyu geng today are made with substitute fish such as "bai bei" rather than authentic Spanish mackerel, so it's worth checking with the vendor.
What is tukuyu geng
Spanish mackerel is a large fish with thick flesh. The fish is cut into slabs four to six centimeters thick, coated in sweet potato starch, and deep-fried until the exterior is golden and set. The broth base is bonito stock lightly thickened with starch; the fried fish slabs go in, and black vinegar and white pepper are added just before serving. The exterior coating is springy while the interior remains tender; the broth combines the fish fat and the bonito for a layered, rich flavor. Peak season runs from winter through the following spring.
A Wen Tukuyu Geng on Magong's Ren'ai Road Night Market is a long-established local institution that has operated for decades, recognized by both visitors and residents as a benchmark shop. The Penghu chapter of Taiwan Snack Map specifically records tukuyu geng as a representative local soup dish of Penghu, and the Penghu County Tourism Bureau's official website has consistently recommended it as a must-try night market snack. It is also available during the busy summer tourist season, but the fish is mainly frozen then, with a noticeable flavor difference from the fresh winter-spring version.

Frequently Asked Questions
When is Spanish mackerel soup in season?
Roughly between the winter solstice and the Lunar New Year, when the mackerel has the richest fat content and strongest aroma.
Is night-market tukuyu geng always made with real Spanish mackerel?
Not necessarily. Genuine premium mackerel is expensive, and media reports indicate many Penghu night-market stalls now substitute other fish species instead.
What's the authentic way to eat it?
Add a ring of black vinegar after the bowl arrives — the sour aroma elevates the broth; some older shops also offer freshly ground white pepper on the table.
