There is a row of simple sheds at one end of the Jagalchi fish market in the southeastern city of Busan.
Almost every stall sells kkomjangeo, or grilled hagfish. Cooked alive, unsurprisingly, the hagfish convulse violently as they sizzle on the grill.
This kind of fish wasn't always eaten in Korea. It was the Japanese who harvested it when they colonized Korea in 1910.
They used the skin to make shoes and discarded the meat. Hungry Busanites gathered the meat, spiced it up, ate it -- and a Busan dish was born.
