Korean fish sauce — anchovy or sand-lance fermented 6+ months in salt. Liquid umami for kimchi alongside saeujeot.
Coastal practice along Korea's South Sea (Tongyeong, Yeosu) and East Sea (Sokcho); the Goryeo-era 1123 Goryeo Dogyeong by Xu Jing already mentions Korean fish sauce as a court provision. Industrial bottling at Yeosu Aekjeot Cooperative began in 1976.
Yeosu and Tongyeong on the South Sea produce 70% of Korean myeolchi-aekjeot (anchovy fish sauce). Sand-lance kkanari-aekjeot from East Sea Sokcho is preferred by Northern-Korean families for whiter kimchi color. Hampyeong's Cheongung-jang has aged in cedar barrels since 1929.
Clear amber-to-mahogany liquid, more viscous than Vietnamese nuoc mam, salt-forward with deep fish-funk and a savory finish. A tablespoon goes into 5kg of kimchi paste; a teaspoon brightens stews. Color check: aged aekjeot turns the deep mahogany of strong tea.
Anchovies layered with sea salt at 1:3 ratio in onggi pots, weighted, drained for 6-12 months at 15-20°C. Halophilic bacteria (Tetragenococcus halophilus) plus fish protease enzymes hydrolyze proteins into free amino acids. The clear top liquid is aekjeot; murky middle layers become solid jeotgal.
Variations
Myeolchi-aekjeot (멸치, anchovy, the standard), kkanari-aekjeot (까나리, sand-lance, milder, Northern-style), saewu-aekjeot (shrimp-based, lighter), Yeosu cooperative bottle, and Hampyeong's cedar-aged premium.

- 110 min
Layer 1 kg anchovies with 300 g coarse salt in a glazed onggi pot.
- 2259200 min
Press with weighted lid; ferment at cool room 6+ months until amber liquid.
Watch outKeep the anchovies weighted down under the brine the whole cure — any bit poking above the liquid grows mold and taints the batch.
- 310 min
Strain through cloth; bottle. Use as fish-sauce backbone for kimchi alongside saeujeot.
Watch outDraw only the clear amber top liquid for aekjeot — dip into the murky middle and you're pulling solids that belong in jeotgal, not the clean fish sauce.
