What You Need to Know
Steaming at 100 °C gelatinizes starch in the wrapper and denatures proteins in the filling, while pan‑frying at 180 °C initiates Maillard browning that creates a crisp edge. Chemical additives such as salt, soy sauce, vinegar, and sugar modulate pH, flavor compounds, and texture, and deviations in temperature or time lead to common failure modes such as soggy wrappers or under‑cooked fillings.
The Science
Primary Reaction
Starch gelatinization and protein denaturation during steaming; Maillard browning during pan‑frying.
