What You Need to Know
During steaming, corn starch granules swell between 60–70 °C, forming a gelatinized network that traps steam and flavors. Lard melts at 40–45 °C, lubricating the masa and contributing to tenderness. Protein denaturation in the filling occurs around 70–80 °C, ensuring safety while preserving texture.
