I think the wrapping actually says to bake it for 25 minutes per pound, so you can use that as a guide. It is pretty accurate. No, I don't put pineapple slices or cherries or coke or anything else on my ham. However, many people do. If you want to place pineapples on top of your ham you can use a toothpick to secure them.
Some people like to pour coke over their ham before cooking.
Season each slice using Mrs. Dash original recipe. Check roast after 2 hours for tenderness and rareness. If pork chops are frozen you will need to defrost them, either in the refrigerator for several hours or in the microwave for a few minutes. If you use the microwave, be sure to take the wrapping off as paper may burn in the microwave. It's best if you don't let them start to cook in the microwave as this makes them a bit tough.
