The Silver Thread of the Deep

Often gracing the tables of weddings and banquets, shark fin symbolizes opulence and prestige in China and beyond. Yet its rise from offcut to delicacy reveals a complex history of how value is constructed and transformed. Drawing on sources in Chinese and English, as well as materials in French, Japanese, Spanish, and Italian, The Silver Thread tracks how this oceanic product came to have symbolic and material value, particularly during the Ming and Qing periods when domestic affluence deepened and became entangled with transregional commerce. Each chapter revolves around a question, such as: How did shark fin make its way from sea to banquet hall? Who advocated for its classification as a delicacy? How were taste, medicine, and ethics intertwined in its consumption?The Silver Thread explores taste, not as a sensation but as a vocabulary of social and moral difference. Shark fin is both an object and an idea at the crossroads of nature and culture, where ritual and economy are mutually implicated, and where excess and moderation coincide. This book is not an apologia for shark fin consumption. It is, in part, a use of history to revisit tradition. Beyond cuisine, Ronald C. Po reconsiders “maritime China” not merely as a sphere of trade, war, or navigation, but as a porous cultural space shaped by meaning and identity.
