A few questions later, I discovered that she'd cooked her ham, because she figured it needed cooking. That's a mistake!
As the USDA explains, you have to read the label to know whether or not you need to cook the ham:
"Hams that must be cooked will bear cooking instructions and safe handling instructions."
"Hams that are not ready to eat, but have the appearance of ready-to-eat products, will bear a prominent statement on the principal display panel indicating the product needs cooking, e.g., 'cook thoroughly.' In addition, the label must bear cooking directions."I don't cook my ham. I typically put a slice of bacon in the frying pan, render some fat and then put the ham in. I brown it a bit, then get it out of the pan and eat it.
Or I take the ham out of the package, warm it a bit, and eat it - like in a sandwich.
Another guy I know puts some sauce on it, then roasts it a bit - but he doesn't cook it - because then it would be too dry.
