Gastrofeminism traces the centrality of food within diverse feminist narratives of agency and resistance. This manifesto introduces the theoretical, pedagogical, and methodological scope of Gastrofeminism to rethink feminist genealogies, legacies, and new embodiments of a radical future. It calls for a reckoning of both established and emerging feminist engagements with food, consumption, and culinary practices. This introduction underscores conjunctures where feminist methodology and pedagogy intersect in variegated social, cultural, and historical settings to engender dialogues on food, eating, and culinary practices. It emphasizes everyday acts of negotiating feminist boundaries and subverting dominant perceptions of food. Furthermore, it contests the practices whereby food is used to reproduce social norms and hierarchies. Gastrofeminism remaps the boundaries of gendered relations through food practices in sites of conflict as well as everyday resistance to gendered norms of domesticity through technological innovations around cooking, eating, and representation of food. This manifesto assembles feminist scholarship and pedagogies committed to pushing the boundaries of traditional food studies and taking it into new, inclusive directions. Gastrofeminism spans across disciplines and praxis to engage with sensory documentation of food, gendered forms of intimacy, appetites and embodiments, food memories, affects, and nostalgia, new feminist pedagogies, foodways, ecosystems and sustainability, and food access, conflict, and social justice.
