What You Need to Know
The process relies on the high specific heat capacity of granite or basalt, allowing rapid conduction of heat to water. As the water reaches 100 °C, proteins denature and starches gelatinize, producing a tender, nutrient‑rich dish. Mineral leaching from the stone can subtly alter ionic composition, affecting flavor and nutrition.
