National Geographic’s The Plate explores the “global relationship between what we eat and why, at the intersection of science, technology, history, culture and the environment”. The latest in its daily discussion on food is the preparation of real stone soup in Oaxaca, Mexico.
The soup originated in a remote ritual site in the Papaloapan River basin, about 12 hours by car from Oaxaca City, in the highlands of the Sierra Madre mountain range. The geography there is very rocky, and in the Pre-Ceramic [period,] Chinantec ancestors developed an elemental way to cook their food using fire and stone. The ritual site features large boulders excavated to serve as large cooking pots, and I guess you might say that the rest is history! The recipe for stone soup features local ingredients and really is a product of this unique environment.
