What You Need to Know
The high humidity and 100 °C steam keep internal protein denaturation below 70 °C, preserving juiciness. Simultaneously, glucose, fructose, and phenolic compounds on the leaf surface undergo Maillard‑like reactions, forming melanoidins that impart a subtle caramelized aroma. The sealed leaf creates a micro‑environment that limits moisture loss and allows delicate flavor development.
