What You Need to Know
During the 4–6 h simmer at 80–90 °C, collagen in the meat denatures to gelatin, while the sugars in coconut milk undergo caramelization, producing brown, nutty compounds. The low temperature keeps the mixture below 100 °C, preventing boiling and preserving delicate aromatics, while the added acid from tamarind or lime lowers the pH to ~4.5–5.0, further aiding protein breakdown.
