We are just in season for Mirugai or Gaper Shellfish.
Known under many names including Mirugai, Mirukui, Mirukuigai, Mirukugai, Guidakku, Umitake or Atlantic Miru, it is a bit grotesque with its vent protruding endlessly.
In Japan it is collected mainly in the sea between Shikoku and Honshu islands.
It can be either dark brown or completely whitish beige.
When consumed as sushi or sashimi, the dark skin is taken off.
It is widely consumed in this country and more are imported from Canada, and Korea. There is practically no difference in taste or quality whatever its origin.
It is particularly popular with sushi lovers with a big appetite!
