This study explores the role of food as an expression of religious identity made evident in things like fasting, feasting, ingredient choices, preparation methods and commensal relations. It considers the role of food in the formation and redefinition of religious identities throughout this period and its significance in the maintenance of ideological and physical boundaries between faiths. This is an insightful and unique look into inter-religious dynamics. It will therefore be of great interest to scholars of religious studies, early modern European history and food studies.
