What You Need to Know
The method relies on protein denaturation and starch gelatinization at 80–90 °C, while the moist environment promotes Maillard browning on the surface. Conductive heat from the stones and radiative heat from the surrounding earth create a stable temperature that preserves juiciness over 6–12 hours.
