Changnan-jeot is jeot of Alaska pollock intestines, a by-product of the pollock catch. The guts are washed and soaked in about 3 % salt water, salted at about 25 %, sealed and ripened about 3 months at 15 °C in the shade, then cut and dressed with chilli, garlic and spring onion.
Total time across the recorded steps: 3 months – 3.1 months

Changnan-jeot is jeot of Alaska pollock intestines, a by-product of the pollock catch. The guts are washed and soaked in about 3 % salt water, salted at about 25 %, sealed and ripened about 3 months at 15 °C in the shade, then cut and dressed with chilli, garlic and spring onion. Made in 6 steps over 3 months – 3.1 months. The longest step, ripen in the shade, takes 3 months (Han J.S. (한진숙)) and runs at 15 °C (Han J.S. (한진숙)). Salt is 3 % (Han J.S. (한진숙)).
Made from pollock intestines alone, which are soaked a day or two in weak brine before salting, and cut and dressed with chilli before eating; most jeotgal is whole seafood salted once.

Salt at about 25 % and a sealed, shaded crock at about 15 °C hold it while it ripens. The Korean Food Code requires changnan-jeot to be stripped, washed and checked with light for foreign matter, and bans adding water or brine to bulk it up.
The folk encyclopedia quotes the 6th-century Qimin yaoshu for a gut jeot sealed in a jar and ripened 20 days in summer, 50 in autumn and 100 in winter, and calls it almost the same as today's method. The Encyclopedia of Korean Culture notes that such early gut jeot need not have been pollock, and dates changnan-jeot to mid-Joseon, when pollock came to Korean tables.
