Nakji-Jeot — Fermented Octopus (낙지젓)

South Chungcheong coastal tradition; nakji (Octopus minor) is most abundantly harvested in the tidal flats of the western coast (서해안) between Incheon and Jeolla

Nakji-jeot (낙지젓) is small octopus (Octopus minor, 낙지, the small Korean octopus — distinct from the large 문어 octopus) preserved in salt and gochugaru and fermented for 2–4 weeks to produce a pungent, intensely savoury fermented seafood banchan. Unlike ojingeo-jeot (squid jeot), nakji-jeot ferments the whole small octopus rather than cleaned rings — the ink, organs, and suckers all contribute to the deeply complex flavour. The result is intensely purple-red, chewy-tender, and carries the full character of the Korean western coastal octopus fermentation tradition. It is a specific jeotgal associated with South Chungcheong (충청남도) coastal villages.

Nakji-jeot's deep, slightly spiced, intense oceanic flavour makes it one of the most assertive jeotgal varieties — a small amount as banchan alongside plain rice provides more flavour intensity per gram than almost any other Korean condiment.
