Ganjang Gejang — Yeosu Style Raw Crab Fermentation (간장게장 여수식)

Yeosu city, South Jeolla province; the fishing port's access to Yellow Sea blue crab and the local anchovy fishing tradition combine to create a distinctive regional gejang style

Yeosu's ganjang gejang tradition (여수 간장게장) represents the most refined expression of raw soy-marinated crab in Korea — using locally harvested Yellow Sea blue swimming crab (꽃게, kkotge, Portunus trituberculatus), cleaned live, and submerged in a repeatedly boiled and cooled soy marinade enhanced with local dried anchovy, kelp, and seasonal aromatics over 5–7 days. The Yeosu style differs from Seoul and Jeolla city versions in its marinade's additional depth from local anchovies and the extended multi-boil cycle that concentrates the soy without making it aggressively salty. The local cold-water crab from the Yeosu Strait has firmer flesh and more richly flavoured roe than inland-sourced crab.

• The repeated-boil marinade cycle parallels the multi-stage pickling technique in Japanese tsukemono (pickled vegetables using repeated brine concentration) and the French confit technique of repeated fat submersion

Yeosu ganjang gejang's roe, spooned directly onto rice and mixed, creates one of Korean cuisine's most intensely satisfying rice experiences — the savoury, slightly oceanic paste combined with plain rice makes the simplest possible meal irresistible.
