What is Tatami iwashi?
Tatami-iwashi is a processed food made from baby sardines ( shirasu ) 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. Tatami-washi 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. This food item is named for its resemblance to a straw tatami mat common in traditional Japanese-style rooms or houses.
