Navana tells the coming of spring with unique bittersweetness. Among the Brassicaceae plants, it refers to those that eat buds, stems, and leaves. In Kagawa, rape blossoms have been cultivated for oil pressing for a long time, but the production of edible navana began around 60. The original variety, Seto no Haru, is popular for its ease of eating with moderate bitterness.
Boiled foods are often pickled in hot spring or pickled mustard, and are sometimes added as a color to handbill sushi made in the spring. The stem can be softened by tearing along the fiber and then boiling.
