Description
Tongan luau cooking uses a pit (umu) to reach 120–150 °C, denaturing proteins and gelatinizing starches while retaining moisture.
Technical
The heat from heated stones and charcoal induces protein denaturation and starch gelatinization, while the quasi‑closed system limits oxygen, reducing oxidation. Coconut milk forms an emulsion that stabilizes heat transfer and prevents surface drying, and Maillard reactions on the meat surface impart savory browning.
