Shiokara

Shiokara lit. 'salty-spicy', is a food in Japanese cuisine made from various marine animals that consists of small pieces of meat in a brown viscous paste of the animal's heavily salted, fermented viscera. The raw viscera are mixed with about 10% salt, 30% malted rice, packed in a closed container, and fermented for up to a month. Shiokara is sold in glass or plastic containers. The flavor is similar in saltiness and fishiness to that of European cured anchovies, but with a different texture. One of the best-known chinmi ("rare tastes"), it is quite strong and is considered something of an acquired taste even for the native Japanese palate.
