What You Need to Know
The process relies on rapid heat transfer from saturated steam, causing starch gelatinization in the wheat‑flour wrapper between 60–70 °C and protein denaturation in the meat filling between 55–65 °C. This results in a firm, moist filling and a pliable wrapper while minimizing moisture loss.
The Science
Primary Reaction
Steam heating → starch gelatinization + protein denaturation
