Myeolchi-Jeot — Fermented Anchovy Sauce (멸치젓)

Coastal Korean production centres, particularly Gyeonggi-do coast, South Chungcheong, and North Gyeongsang province where anchovy fishing is traditional

Myeolchi-jeot (멸치젓) is whole small anchovies (Engraulis japonicus) preserved in sea salt at a 1:3 ratio, fermented in onggi pots for 6–12 months until the fish dissolve into a liquefied amber paste. The liquid strained from this mass is myeolchi-aekjeot (멸치액젓, anchovy fish sauce), one of Korea's two primary fish-based liquid seasonings alongside saeujeot brine. Myeolchi-jeot is the dominant fish ferment used in kimchi across the central provinces (Chungcheong, Gyeonggi), particularly where saeujeot is considered too sweet. The paste itself, before straining, is also used directly in kimchi making in Chungcheong-do style, giving a more intense fermented fish depth.

Myeolchi-aekjeot in kongnamul-guk (bean sprout soup) produces a depth that ordinary salt cannot — the fermented amino acids create a background savouriness that makes the soup taste complete without needing stock. It is the invisible backbone of most Korean soups made at home.
