What is a sign of overcooking in pre-cooking process?

A sign of overcooking during the pre-cooking process is often indicated by a burnt taste. When food is overcooked, the Maillard reaction and caramelization processes can progress too far, leading to the development of burnt flavors. This strong, unpleasant taste typically results from excessive heat exposure, which can also cause the outer surfaces of food to char or darken significantly.

In contrast, soft resistance, even cooking, and soft interior might suggest that the food has been cooked just right or is undercooked, rather than overcooked. Thus, recognizing a burnt taste serves as a crucial indicator that the food has exceeded the appropriate cooking time or temperature during the pre-cooking stage.
