The study of persuasion in texts focuses on the means and strategies to alter the audience’s attitude and on bringing about a change in their minds. Persuasion can seldom be associated with linguistic phenomena or categories, or in other words, linguistic categories often contribute towards the persuasiveness of a text, carrying other functions at the same time. This chapter will investigate the ways in which persuasion is interlaced with the informative and instructive contents of Early Modern English medical recipes, looking beyond the customary recipe collections into other medical genres and the recipes embedded in their texts. The approach adopts metadiscourse analysis as a tool to map linguistic item inventories by which to anchor the classical concepts of persuasion to linguistic phenomena. The study suggests that persuasion in medical recipes resides in such linguistic phenomena that can be identified by metadiscourse categories. The approach provides a useful tool for triangulating one’s observations about the persuasiveness of a text. One of the trends emerging in the Early Modern English period is the increasing variety of metadiscourse classes used in recipes.
