What You Need to Know
Saturated steam transfers heat to the dough, gelatinizing starch granules and softening the gluten network, while the high temperature denatures myosin and collagen in the meat, causing the characteristic broth to form. Precise timing ensures the proteins reach safe internal temperatures without over‑cooking the wrapper.
The Science
Primary Reaction
Heat transfer via saturated steam leading to gelatinization of starch and denaturation of proteins
