Preheat the oven to 300 degrees.

Place the ham on a rack in a roasting pan. Using a very sharp knife, slice the ham in one direction and then again in the other direction; making a diamond pattern on the ham.

Poke the cloves in the center of each of the diamonds.

Cover the ham with foil and bake for an hour.

While the ham is cooking, make the Dr Pepper glaze.

In a saucepan, add the brown sugar, mustard, apple cider vinegar and the Dr Pepper. Bring the mixture to a boil, then reduce the heat and simmer for 15 minutes until thick and amazing.

After the ham has cooked for an hour, remove the foil and brush the glaze all over. Then put it back in the oven and cook for another 20 minutes. Do this for a total of three times until there is a thick layer of glaze.

Slice the ham and serve!
