The Bento Lunch Book is an illustrated cookbook about the Japanese lunchbox. What distinguishes the Japanese lunchbox from our Western lunch containers? To understand this, one must know how the Japanese eat. The traditional Japanese culinary culture, Washoku, was designated as a UNESCO Intangible Cultural Heritage in 2013. One of the fundamental rules of Washoku states that a meal must contain at least five different colors, five different flavors, and five different cooking methods. This is because, as many Japanese believe, only by consuming a wide variety of foods can one ensure complete nutritional intake. The bento box is the solution for on-the-go meals. It combines all these different foods in the most compact space within a single box. The book accompanying the box is suitable for both beginners and advanced users.
