To commemorate its 100th anniversary the heads of newspaper Tozai Shimbun come up with a plan to publish the “Ultimate Menu”. The assignment is given to journalist Yamaoka Shiro, the protagonist of the series. With the help of a female coworker, Kurita Yuko, Yamaoka starts off on what can only be termed an epic saga to find the dishes hat will go into the “Ultimate Menu”. The subject of volume 1 is Nishon ryori, or Japanese cuisine, featuring stories on subjects like how to prepare a proper dashi (broth that is one of the building blocks of Japanese cooking), or matcha (the powdered green tea used in the tea ceremony), or red snapper sashimi. The subjects of the later volumes are: 2) sake, 3) fish, 4) vegetables, 5) rice dishes, 6) udon, and 7) izakaya or “pub” food.
