About this ingredient
Boiled-and-dried small sardines (typically Japanese anchovy, Engraulis japonicus) used as a dashi base distinct from kombu/katsuobushi. The Seto Inland Sea (especially Iyo-nada) is the primary production region, where 'iriko' is the local name. Niboshi-based dashi is the foundation of regional ramen broths (especially Tsukemen), miso soup in many Japanese homes, and increasingly export-grade premium dashi packets. Calcium content makes niboshi a target for functional food positioning.
