What You Need to Know
The method relies on controlled heat (120–140 °C) and moisture retention to denature proteins and release gelatin, which gives the dish its characteristic tenderness. Simultaneously, the low‑oxygen environment at the lid promotes Maillard browning, producing melanoidins that deepen flavor and color while retaining volatile aromatics.
