🍱 Japanese saltwort in mustard dressing

The Japanese saltwort used in this dish was originally a wild plant that grew along the coast and came to be called okahijiki because it looks like hijiki, a seaweed. In Yamagata Prefecture, it is said that the seeds of the Japanese saltwort, which grew wild in the Shonai area by the sea, were introduced by boat across the Mogami River to Sunazuka Village (present-day Nanyo City), a sandy area under the Yonezawa Domain, where its cultivation began. In the Honzo Zufu (1828), it is mentioned in the "Wo Kamiru" section as "Wo Kahishiki" Ushu Yonezawa, indicating that it has been a production center since the Edo period. Nanyo City is considered to be the birthplace of Japanese saltwort, and even today, it is actively produced as a traditional vegetable that the local people are proud of. As a wild species, it is very vigorous and can be expected to produce a large yield if the soil is suitable. Even after being picked once, the leaves sprout immediately. Therefore, depending on the care of the plant, it could be harvested many times.
