What are the appearance characteristics of corn when cooked properly?

When corn is cooked properly, it should appear bright yellow and free of wrinkles. The bright yellow color indicates that the corn is fresh and has retained its vibrant pigments during cooking, which often enhances its sweetness and flavor. The absence of wrinkles is also a key appearance characteristic of well-cooked corn, as it suggests that the kernels have plumped up properly during the cooking process, maintaining their moisture and tenderness. This combination of bright color and smooth surface signals that the corn has been cooked just right, preserving its appealing texture and taste.
