Umeboshi plum is mashed and mixed with mirin, soy sauce and powdered bonito flakes to make bai-niku or ‘plum flesh’, the main ingredient in the roll known as ume-maki. The flesh of the plum being small in quantity, extra rice is incorporated in the roll to compensate. A generous helping of plum is included, with wasabi in almost equal measure. Finely chopped shiso is laid out, rice and plum. Ume-maki displays its true worth when the quantities of plum and wasabi, shiso and sesame are in perfect balance with the rice. A popular roll often served as a palate cleanser at the end of a sushi meal.
