What should the upper and lower temperatures be of the platens on the clamshell grill when cooking products?

The correct answer involves understanding the recommended cooking temperatures to ensure food safety and optimal cooking quality when using the clamshell grill at McDonald's. The upper temperature of 425 degrees Fahrenheit allows for sufficient heat to create a sear on the food, enhancing flavor and ensuring that the outer layer of the food is cooked properly.

The lower temperature of 365 degrees Fahrenheit is suitable for maintaining even cooking throughout the product without overcooking or undercooking it. These specific temperatures help achieve the desired result of safely cooked food that meets the brand's quality standards while also assisting in managing cooking times effectively.

Using these parameters not only aligns with food safety guidelines but also helps in achieving consistency across products cooked on the grill, ensuring customer satisfaction.
