The Secret Ingredient is produced at KUT Radio in Austin, Texas, and it reads food the way a historian reads a document: as a record of who worked, who profited and who went without. Three people share the hosting. Rebecca McEnroy is host and executive producer at KUT. Raj Patel is an author and a professor at the LBJ School of Public Affairs, and Tom Philpott is the food and agriculture correspondent for Mother Jones and the author of 'Perilous Bounty'. Episodes are built around guest conversations, and the questions put to guests are political ones. Some episodes open on a jumble of ad-style slogans, a healthy breakfast here and two pizzas for the price of one there, before the talk turns to climate or trade. The episode with Frances Moore Lappé names hope itself as the ingredient and starts from Pandora's box, the Christian virtues, Kant and Nietzsche. Then it gets concrete. The guest describes how hard it has become for many people to live near a store with fresh food, and how family income once rose across every class before money began rushing to the top after the early 1970s. The COVID-19 series treats the pandemic as a test of a fragile food system and of the essential workforce it depends on. In the installment with Rob Wallace, the conversation rejects the claim that large-scale operations are biosecure and notes that state governors moved to suspend collective bargaining rights for workers. Ben Lilliston's episode on the Green New Deal asks what a trade deal built around local production, farmer income and climate resilience might look like. It also takes a self-described wonky turn into supply management, pointing out that sugar and cranberries already run under such systems. The show also travels well beyond Austin. A conversation about Guam calls the U.S. base there a 'spatial fix' for American troops positioned against China, then moves to the Progressive International and the argument that solidarity across movements is the only way forward. Rita Valencia and Charlotte Sáenz bring in the Proceso de Liberación de la Madre Tierra, whose aim of freeing Mother Earth rather than reclaiming territory drew in one of the speakers. The same episode describes cutting sugarcane, sharing chicha and the joy of working together, which people in Colombia call la juntanza. Sugar comes up in more places than those. An extended interview with the late anthropologist Sidney Mintz, who did the fieldwork for 'Sweetness and Power' in Puerto Rico, revisits a conversation the show first ran in September 2015 and covers his work on sugar, the development of anthropology and his role as an educator. The tone throughout is earnest, and the show makes no show of neutrality: its sympathies lie with workers, smallholders and movements for equity. For sugar history, the Mintz interview is the obvious way in. For policy, try the Lilliston episode, and for the widest frame, the conversation on hope.
