Ham should not sit at room temperature any longer than 2 hours.
If it is not within 5 degrees, return it to the heat source, wait 10 minutes, and then check the temperature again. Repeat this process until the ham is 5 degrees or less from the desired internal temperature. The ham should be left standing for 10 to 15 minutes before carving. During the standing time it will continue to cook and the temperature should rise to the appropriate internal temperature. This will ensure that the ham will not be overcooked.
