What You Need to Know
During steaming at ~100 °C the coconut‑milk emulsion stabilizes the fish, preventing drying while the mild acidity from lime or tamarind denatures collagen, leading to gelatinization. The gentle heat preserves omega‑3 fatty acids and limits oxidation, while the banana‑leaf enclosure creates a moist micro‑environment that locks in aromatic compounds from lemongrass and galangal.
