What You Need to Know
During steaming, the wrapper’s internal temperature rises to ~100 °C, triggering starch gelatinization between 60–70 °C and protein denaturation above 70 °C. This process develops a gluten network while preserving moisture, resulting in a wrapper that is both sturdy and moist. The technique also relies on controlled fermentation to enhance gluten development and flavor.
