Digital technology has become a frequent companion of daily food practices, shaping the ways we produce, consume, and interact with food. Smart kitchenware, diet tracking apps, and other techno-solutions carry promise for healthy and sustainable food futures but are often problematic in their impact on food cultures. We conducted four Human-Food Interaction (HFI) workshops to reflect on and anticipate food-tech issues, using experimental food design co-creation as our primary method. At the workshops, food and food practices served as the central research theme and accessible starting point to engage stakeholders and explore values, desires, and imaginaries associated with food-tech. Drawing on these explorations, we discuss diverse roles that experimental design cocreation, performed with and around food, can play in supporting critical, interdisciplinary HFI inquiries. Our findings will appeal to design researchers interested in food as a research theme or as a tangible (and compostable!) design material affording diverse co-creative engagements.
