Carry over cooking

From Wikipedia, the free encyclopedia

Carry over cooking refers to the phenomenon that food retains heat and continues to cook even after being removed from the source of heat.[1] The larger and denser the object being heated the greater the amount of carry over cooking. After being removed from the heat source (oven, grill, etc.) the internal temperature can continue to increase. This means that when cooking large roasts or turkeys, for instance one must often pull the item out of the oven when it is still a little raw on the inside in order to avoid overcooking.

[edit] Physics

As mentioned above, the larger and denser the object being cooked, the greater the degree of carry overcooking. In more scientific terms, larger objects have a lower surface area to volume ratio and thus retain heat better. Denser foods typically have more water content. Water has a higher heat capacity and thus there is more heat in the food object to continue the cooking.
