The anchovies for
Myeolchi-jeot are harvested along the southern coasts of the
Korean Peninsula en masse.
Myeolchi-jeot used in the process called
gimjang are prepared with mature anchovies known as
osari-myeolchi (flood tide anchovies), which are harvested in July and August. On
Jeju Island, bigger anchovies harvested in the spring along the coasts of
Seogwipo are made into
meljeot. Cleaned fresh anchovies are drained on
sokuri (bamboo baskets), and salted with
coarse salt weighing 15‒20% of the anchovies. In an
onggi (earthenware jar), the anchovies and salt are put in layers, with the uppermost layer being a thick layer of salt, to prevent the anchovies from coming in contact with the air. The jar is sealed, and the salted anchovies are then allowed to ferment at for two to three months in
onggi (earthenware jars). Once the
myeolchi-jeot has aged another couple of months, it becomes
myeolchi-jeot-guk (anchovy extract). == Culinary use ==
