What You Need to Know
During steaming, rice starch gelatinizes at 60–70 °C, swelling and leaching amylose and amylopectin into a viscous matrix. Egg proteins denature between 62–65 °C, forming a network that traps steam and stabilizes the crumb. The natural lecithin in coconut milk keeps the fat emulsified, preventing separation and contributing to a moist texture.
