What does it mean for food to be authentic? Who owns this or that recipe, ingredient, or flavor? Why do we care? This week Brian Lowery speaks with documentarian, writer, and professor of food studies, Von Diaz. She discusses the fusion of island culinary traditions with Southern-style cooking, and what she's been studying about food and authenticity. Plus, Brian looks back on a conversation with Tunde Wey, a Nigerian artist, writer, and cook who uses food to investigate issues of racism, colonialism, and wealth inequality.
