What You Need to Know
The conduction of heat from stones raises the internal temperature of the masa to the boiling point of water, triggering starch gelatinization and protein denaturation. The moist, anaerobic environment suppresses Maillard browning, preserving a uniform, tender product while imparting subtle earthy and leafy aromas.
