The aperture is controlled within an optimal range, holes are evenly distributed, and their quantity is set according to the heat-dissipation curve of common fried and grilled foods — ensuring excess moisture escapes continuously without causing rapid heat loss from over-perforation. The lid features a slightly domed profile that creates a gap between the lid and the food surface, preventing crispy coatings from directly contacting the inner lid and becoming soggy from condensed moisture — a structural detail that plays a critical role in preserving texture.
