Hongeo-hoe is a type of fermented fish dish from Korea's Jeolla province. Hongeo-hoe is made from skate and emits a very strong, characteristic ammonia-like odor
Skates (hongeo) are cartilaginous fish that excrete uric acid through the skin, rather than by urinating as other animals do. As they ferment, ammonia is produced, which helps preserve the flesh and gives the fish its distinctive, powerful odor.
