What it is

Fish preserved between layers of cooked rice and salt, fermenting by lactic acid and eaten without the rice. Sushi derives from this method of preserving fish.

An origin in Southeast Asia (Mekong) is the common hypothesis, supported by the distribution of similar preparations; the Chinese dictionary Shuowen jiezi (121) already defines a fish preserve in rice. Date and place are inferred.
