How deep should food be poured into cooling pans for effective cooling?

Pouring food into cooling pans at a depth of 1–2 inches is recommended for effective cooling because this depth allows for optimal heat transfer and airflow around the food, facilitating faster cooling. Shallow depths increase the surface area of the food exposed to cooler air, which helps to lower the temperature more rapidly, minimizing the risk of bacterial growth.

When food is placed too deeply in a cooling pan, heat can become trapped in the center, slowing down the cooling process and potentially allowing harmful bacteria to thrive. Maintaining a depth of 1–2 inches strikes a balance that promotes efficient cooling while ensuring food safety.
