It uses 'early-harvested Makonbu' from southern Hokkaido. This is young kelp that has traditionally been 'thinned out' during the aquaculture process, featuring soft leaves that make it an ideal ingredient for rice balls. We combined the soft texture and umami of the early-harvested Makonbu with the refreshing pungency of mountain wasabi, a favorite in Hokkaido, and the mildness of mayonnaise, creating a highly satisfying dish.
