Saeu-jeot

Saeu-jeot is a variety of jeotgal, salted and fermented food made with small shrimp in Korean cuisine. It is the most consumed jeotgal along with myeolchi-jeot (멸치젓, salted anchovy jeot) in South Korea. The name consists of the two Korean words saeu (새우, shrimp) and jeot. Saeu-jeot is widely used throughout Korean cuisine but is mostly used as an ingredient in kimchi and dipping pastes. The shrimp used for making saeu-jeot are called jeot-saeu (젓새우) and are smaller and have thinner shells than ordinary shrimp.

The quality of saeu-jeot largely depends on the freshness of the shrimp. In warm weather, fishermen may immediately add salt for preliminary preservation.

Types
The types of saeu-jeot depend on the kind of shrimp used and when they are harvested.

In spring
Putjeot is made with shrimp harvested from the end of January In the Korean calendar (lunar) through April. It is called deddeugi jeot or dotddegi jeot  in the west coast of the South Korea. Ojeot is made with shrimp harvested in May.

In summer
Yukjeot (육젓, 六젓, six [month] jeot) is made with shrimp harvested in June and is regarded as the highest quality jeot. It is the saeu-jeot most preferred for making kimchi because of its richer flavor and bigger shrimp than other saeu-jeot. The shrimp in Yukjoet have red heads and tails. Chajeot is made with shrimp harvested in July.

In fall
Gonjaeng-ijeot or jahajeot  is made with very small shrimp-like Neomysis awatschensis, one of the opossum shrimp family which is called gonjaeng-i or jaha  in Korean. The shrimp used for it is the smallest among all saeu-jeot. They are harvested in August and September in small amounts where freshwater mixes with seawater of the abyss of the Yellow Sea. As it ferments, the jeot changes from transparent to light violet or brown in color and becomes soft in texture. Gonjaeng-ijeot is called gogaemijeot in Jeolla Province. It is a local specialty of Seosan-gun, Chungcheong Province.

Chujeot is made with small shrimp harvested in autumn which are smaller and cleaner than the shrimp in yukjeot.

In winter
Dongjeot is made with shrimp harvested in November. Dongbaekha (동백하젓 冬白蝦) is made with shrimp harvested in February whose bodies are white and clean.

Jajeot is commonly called japjeot (잡젓, literally mixed jeot) which is made with several types of small shrimp without special selection. Daetdaegijeot is made with shrimp that have thick, stiff, yellowish shells. It is considered to be the lowest quality saeu-jeot.
