Professor Rath studies Japanese cookbooks, recipe collections, and gastronomic writings from the period 1400 to 1868 to trace the development of Japanese cuisine. Interesting fact is that some of these writings were not meant as serious recipes to be used for food preparation, but as purely literary exercises in concocting fanciful foods and banquets, a sort of "fantasy food rituals." In a more practical sense, Rath also traces the origins of more familiar dishes as sushi, sashimi and tempura. A fascinating study of Japanese food history.
