What You Need to Know
The method relies on thermal conduction from hot stones (~200 °C) and steam to denature proteins and gelatinize starches while preserving moisture. High humidity (~90–100 %) suppresses Maillard browning, and banana leaves impart phenolic antioxidants that reduce fat oxidation.
