Definitions

• the present invention relates to a method, suitable for ovens, comprising some steps to enhance the cooking efficiency and performance.
• the browning level is one of the most critical quality indicators for the foods cooked in the oven. While a good browning is desired on the upper surface at the end of cooking in foods such as fish and chicken, the level of browning on the bottom surface is more important in doughy foods and is perceived as a quality indicator.
• users usually complete the cooking by placing the baking tray on a lower or upper shelf after cooking the food in a shelf position for a certain period of time.
• the food center must first reach a sufficient degree of cooking. Otherwise, as a result of transporting food to an upper or lower shelf, the surface of the food remains raw while the surface is overcooked.
