"Traditional Earth Ovens" explores the fascinating history and engineering behind underground cooking methods used by indigenous cultures worldwide. It unveils how these earth ovens, like the Māori Hangi and Polynesian Umu, represent sophisticated systems that highlight thermal efficiency and promote sustainable cooking. These ovens aren't just primitive holes in the ground; they're carefully constructed thermal devices leveraging the earth's natural insulation to maintain consistent temperatures, enabling communities to cook large quantities of food for feasts and gatherings.

The book examines the physics of heat retention, the variety of designs across different cultures, and the socio-cultural importance of earth ovens. It reveals how the ovens are not only a means of food preparation but also a center of community building, often involving collaborative efforts in their construction and use.

From archaeological findings to ethnographic studies, "Traditional Earth Ovens" progresses by exploring the fundamental principles before branching into regional traditions and concluding with modern applications, making it a valuable resource for anyone interested in culinary history, anthropology, or sustainable living.
