The Korean people have used pickled dishes in their dietary life from long time ago. Pickled dishes made with shrimps go well with vegetables and preserve the natural flavor of shrimp.

Pickled dishes made with sand eel, shellfish, oyster, squid, razor shell and others can be used as not only dishes served to go with rice but also spices of other dishes.
