Tips for cooking smoked ham cover both safety and preparation methods. It is important to use an accurate meat thermometer to ensure the meat reaches the proper internal temperature. This is between 140 and 170 degrees Fahrenheit, depending upon the cut of the ham.
For best results, a frozen smoked ham should be fully thawed before cooking. When the ham is in the oven, cover it loosely with foil to keep it from becoming too dry. Another trick to keep moisture in is to add a small amount of water to the ham's roasting pan. Once the ham is done cooking, leave it covered and let it stand for 10 to 20 minutes before serving. Larger hams require more standing time.
