To build modern starch reference collection, I'm looking for some literatures about famine foods in Japan, and I found this old book.
Katemono (the old usage of famine food in Japanese, Japan College of Social Work Digital Library)
*This is written in the old Japanese language.
After a serious famine in Temmei (Edo period, 1783), Yonezawa clan (now southern east of Yamagata Prefecture) ordered a guidebook about famine foods. All pages are digitalized on the net, and so we can see this book easily.
This contains how to use and cook horse chestnut (Aesculus turbinata), bracken fern (Pteridium aquilinum), nobiru (Allium macrostemon), kudzu (Pueraria lobata), and asatsuki (Allium schoenoprasum var. foliosum), and other species. Reading old Japanese literatures is hard for me, but I'm studying this kind of books.
