The fourth film in our Mexico series takes us to Oaxaca. The city is a culinary Mecca and there's no ingredient more important to the region—or the country, for that matter—than corn. We met with Amado Ramirez Leyva, the guru of Mexican corn. He runs a small restaurant called Itanoni, where only the best corns and most traditional foods are served (mostly corn and beans). But his food philosophy extends beyond the menu into the spiritual realm. His reverence for this ancient food was an inspiring reminder of why we need to hold on to what is real.
