Tortillas, tortilla chips, and tamales—these are all foods that are easy to enjoy but not as easy to make from scratch. There's a process called nixtamalization that occurs, which unlocks nutrients from corn and makes it ready to use in the foods we love. Nixtamalization is a crucial step, yet it's not well-known. It's a testament to the ingenuity of Indigenous science, which has been subject to erasure throughout history. In this episode of Proof, Navajo reporter Andi Murphy walks us through her journey of nixtamalizing blue corn, and embarks on an Indigenous information exchange with chefs, scholars, and poets in the process.
