Matsumae pickles
A traditional Japanese pickle dish from Hokkaido, made with dried squid, kombu, and herring roe pickled in a soy-based sauce.
I bought Matsumae pickles as a souvenir from Hokkaido.
Matsumae pickles go well with rice.
Named after the Matsumae region in Hokkaido, where this pickle dish originated. The exact historical derivation is uncertain.
