Sikhae is a salted fermented food with grains in Korean cuisine as one of jeotgal. "Sikhae" is made with various fish, such as flat fish, shellfish, pollack, squid and fish intestines, and cooked grains, such as rice, glutinous rice, glutinous foxtail millet and nonglutinous millet. "Sikhae" is less salty than jeotgal because most jeotgal is made with seafood and salt, but "sikhae" is made with not only the ingredients of jeotgal but also grains, shredded radish, etc. Therefore, "sikhae" is stored for short-term, while jeotgal is able to be stored for rather long-term because of the large amount of salt.
