Lewicki's West African Food in the Middle Ages is one of those useful reference books for anyone interested in finding out more about the alimentary factors in the history of Sudanic West Africa before the changes wrought by the introduction of American crops after 1492. It covers the period from the 900s until the early 1500s, mainly drawing from medieval external Arabic sources and later post-Leo Africanus sources from Europe or West African chronicles. For anyone interested in the Western Sudan from Takrur and the Senegambia to Mali and Songhay, there will be some useful information. Even Hausaland, Saharan and Sahelian Tuareg, Mauritania, Kanem, and Borno are included. The societies south of the savanna are usually omitted, though references to kola and Yoruba cuisine will occasionally appear in the text.
Unfortunately, since the book is basically a list of the various types of food and some of the dishes prepared in West Africa's Sahel and savanna lands, there is not too much in the way of analysis. Moreover, since many of our sources are external Arabic geographies or accounts, there is a lot of room for error, doubt, and uncertainty. For instance, Lewicki theorizes from al-Umari's account of Mali that criminals or convicts may have been sacrificed in an annual yam ritual akin to that of the Asante and other groups south of the empire of Mali. He could very well be correct, but there are too many uncertainties and unknown factors in the interpretation of the Arabic sources or the chronology of certain customs or culinary habits. Some dishes and drinks, such as mead, the use of millet for beer and porridges, sorghum, and milk or butter, appear across the region and are probably of very deep antiquity in West Africa. Imported spices and things such as wheat, onions, lemons, peaches, and sugarcane attest to changes in consumption patterns tied to trade, migration, and cultural shifts. One can look at, for instance, al-Bakri's description of Awdaghust, with its North Africans (coming from societies where wheat was an important crop) and its black women slave cooks well-known for their confections as an example of the probable culinary culture that characterized other Sahelian trading towns or centers.
Despite the structural problems of this book basically consisting of a series of lists and some of the necessarily speculative theories or conclusions, it really does provide greater clarity as to the basic diet of various West African peoples. The ancestors of the Imraguen of Mauritania, who feasted on sea turtles, or the Bambara consumption of dogs is explained adequately. Widespread eating of carrion is also elucidated, bringing more context to Ibn Battuta's negative perception of dietary habits in Mali. Moreover, the early introduction of Mediterranean and Asian crops or domesticates in West Africa raises all sorts of interesting questions. Lewicki was writing at a time when Arkell's theory of Christian Nubian influence in lands west of the Nile was great, but looking at Kanem, one finds early references to sugarcane and Mediterranean crops. Some of these were not common in Borno during the 19th century but one cannot avoid the obvious conclusion that Kanem-Borno was part of a complex pattern of agricultural and cultural change across West Africa.
