"Cups and Their Customs" by George Edwin Roberts and M. D. Henry Porter is a culinary guide written in the late 19th century. This work focuses on the history, preparation, and customs surrounding a variety of drinks known as "cups," which often consist of compound beverages made with different ingredients. The authors seek not only to provide delicious recipes but also to trace the historical significance and social customs linked to drinking. At the start of the book, the authors introduce the concept of "cups" along with a brief historical overview of drinking customs through the ages, from ancient mythology to modern practices. They express a desire to revitalize sociable and wholesome drinking habits, contrasting them with contemporary norms they deem uninspiring. The preface emphasizes the importance of understanding the cultural background behind various drinks, as well as the intricacies of their recipes, promising practical guidance for those looking to experiment with these traditional communal beverages.
