What do grill marks indicate?

Grill marks are a visual indication that the meat has been properly seared, which involves cooking it at a high temperature to create a flavorful crust. This searing process not only enhances the taste and texture of the meat by caramelizing the exterior but also contributes to the overall presentation, making the dish more visually appealing. Properly developed grill marks suggest that the meat was placed on a hot grill for long enough to achieve this browning effect without being burnt. They signal that the grilling technique has been executed correctly, showcasing the skill of the cook in achieving both flavor and aesthetics in the final product.
