Because it had to be salted to survive the journey. Andong sits deep inland in the mountains of North Gyeongsang province, a long way from any coast. Before refrigeration, mackerel carried over the hills from the east coast would have spoiled — so it was salted heavily on the road. What began as preservation became the taste people wanted, and a landlocked Confucian town ended up famous across Korea for a sea fish.
What gangodeungeo actually is
간고등어 (gangodeungeo) is mackerel that has been salted and lightly cured, then grilled. The salt firms the flesh and concentrates the flavour — it is nothing like fresh grilled mackerel, and that is the point. It arrives as a whole split fish, crisp-skinned, served with rice and side dishes.
The traditional method salted the fish at a specific point on the journey, judged so that it would be perfectly cured by the time it reached Andong market. The salting was a craft, and the men who did it had a name.
Where to eat it in Andong
The restaurants around the old town and Wolyeonggyo Bridge are where to look. Central Andong, near the old market, is the jjimdak end of town.
Which brings up the thing most visitors get wrong.
Don't eat jjimdak twice
안동찜닭 — braised chicken with glass noodles in a sweet soy sauce — is Andong's famous dish, and almost every visitor eats it for both meals and goes home thinking that is the local food.
It is worth eating once, in Jjimdak Alley at the old market. But it is also the newest of Andong's dishes: it was invented by market vendors in the 1970s, when Andong's old "Chicken Alley" needed something to compete with the Western-style fried chicken shops spreading across Korea. It became a nationwide hit and the street was renamed after it.
Salted mackerel is older, stranger and more particular to the place.
The other two Andong dishes
- 헛제사밥 (heotjesabap) — rice with a spread of small dishes, based on the food prepared for Confucian ancestral rites. Restrained, vegetable-heavy and very Andong, in a city that was the centre of Korean Confucian scholarship.
- 안동국시 (Andong guksi) — hand-cut wheat noodles in a light beef broth. The everyday one.
Between them, those three dishes tell you more about Andong than any museum: a Confucian ritual meal, a preserved sea fish from a town with no sea, and a 1970s market invention that conquered the country.
And the soju
안동소주 is a distilled rice spirit at 45%, protected as regional intangible heritage, and nothing like the green-bottle soju sold everywhere else. Drink it slowly, in small cups.
The 45% is not a tradition, incidentally — it is a tax band. Traditional distilling produced a range of strengths, but when Andong soju was first commercialised under Japanese-era licensing rules, a single fixed figure was needed to assess duty. The number stuck, and one of Korea's oldest spirits has its strength set by a colonial tax office.
