What should be avoided to ensure maximum air circulation while cooling food?

To ensure maximum air circulation while cooling food, stacking pans should be avoided. When pans are stacked on top of each other, it restricts the airflow around the food contained within them. Proper air circulation is crucial during the cooling process because it helps maintain safe temperatures and reduces the risk of bacterial growth.

Using shallow pans actually promotes better air circulation because they have a larger surface area, allowing heat to dissipate more rapidly. Storing food in plastic containers can be acceptable if the containers are designed to facilitate airflow, but generally, the shape and size of the container matter. Cooling in a freezer is effective for speed, but if food is not correctly placed or if the freezer is overcrowded, it can lead to uneven cooling. Therefore, avoiding stacking pans is essential for achieving optimal cooling conditions.
