Dried Fish Matters is a comprehensive project focused on understanding the immense significance of dried and fermented fish in South and Southeast Asia, not just as a food source, but as a cultural, social, and economic cornerstone. Despite being integral to the regions, the vast economy surrounding dried fish has remained largely underrepresented in both research and policies. This initiative collaboratively brings together experts from six countries to shed light on this overlooked domain. The resultant volume is a rich tapestry of essays, stories, and even recipes that underscore why dried fish is paramount – be it to the researchers, the local communities that depend on it, or humanity's culinary legacy. Released in honour of Sustainable Gastronomy Day 2022, the project underlines the multifaceted values of dried fish, emphasizing its role in sustainable development and wellness.
