In recent decades, historians of medicine and science have revolutionised the study of pre-modern heath and healing by focusing on sources that provide historians with new insights into popular medical practices, the transmission of ideas and the complex interactions of gender and social hierarchies within networks of intellectual exchange. In Recipes and Everyday Knowledge, Elaine Leong continues this tradition by bringing to life the ‘recipe fever’ of seventeenth-century England. This study focuses on the handwritten books of household recipes and networks of domestic exchange among early modern landed gentry. Leong uses recipes as a method for investigating the creation and transmission of ‘vernacular practical knowledge’, revealing how early modern people maintained their own state of health, developed techniques to produce improved foods and medicines, and conducted individual experiments using natural pharmaceuticals.
