Tatami Iwashi (タタミイワシ) is a Japanese processed food product made from baby sardines or shirasu (白子 / しらす) laid out and dried while entwined in a single layer to form a large mat-like sheet. Typically, this is done by drying them in the sun on a bamboo frame, a process that is evocative of the manufacture of traditional Japanese paper.
Tatami Iwashi can then be cut to various sizes and used in different ways. Common serving styles include use as an ingredient in soup or cut into small pieces for use as a snack or accompaniment to sake or beer drinking, known as sakana.
