Tatami iwashi is a Japanese processed food product made from baby sardines or 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, a process that is evocative of the manufacture of traditional Japanese paper.

Origin: Japan

Serving Suggestions: Cut into your desired shape and can be deep fried to add an extra crunch.
