What You Need to Know
The slow simmer at 80–90 °C allows collagen to hydrolyze into gelatin, creating a moist, tender texture. The addition of soy sauce, sugar, and aromatics triggers a Maillard reaction at ~140–150 °C during the final 30 minutes, producing melanoidins that deepen flavor and color.
