À propos de cet ingrédient
The mid-tier kombu of choice for everyday Japanese cooking and the most common kombu in Japanese supermarkets. Produced along the Hidaka coast (south-central Hokkaido), Hidaka kombu cooks softer than rishiri or ma-kombu, making it ideal for both dashi and direct consumption (kombu-stewed tofu, kombu salad). Mitsuishi (formerly within the Hidaka district) is the historic harvest centre. Commercial volume is significantly larger than rishiri/rausu/ma-kombu, with substantial export volume to overseas Japanese-restaurant supply.
