This is hands down the single best book on the history of Ottoman cuisine. I have read many books written by modern Turkish scholars, but they are often circular, each quoting each other, and making the same comments repeatedly. They are useful but fail to discuss the influences of the variety of ethnic and religious populations in the Ottoman capitals and other regions. The authors are clearly constraining themselves to the governmental line.
Mary's book is not constrained by Turkish nationalism. This is not a cookbook, although it has an occasional recipe. Rather, it honestly discusses Turkic, Jewish, Byzantine, Christian, Persian, and other influences on the development of cuisine in the Ottoman Empire over the many centuries of its existence. It includes information on the changing array of ingredients, dining etiquette, the effects of uprisings within the empire on the availability of foods, and governmental controls related to food. It is beautifully illustrated in color with Ottoman art, photographs, and illustrations by Europeans who visited the Empire. Very highly recommended.
