"Preparing a Christmas ham requires a few essential steps. First, select a high-quality ham that is bone-in and has a good balance of fat to meat. Next, soak the ham in cold water overnight to remove any excess salt from the brine solution. Then, bake the ham at 325 degrees Fahrenheit for 12-15 minutes per pound, until it reaches an internal temperature of 145 degrees Fahrenheit. Finally, let the ham rest for 15 minutes before carving and serving it with your favorite sides."
