* Ham should be one of the precooked hams. Not one of the specialty cured or canned hams. Just the standard bone in ham in the meat counter. +++++++++++++++++++++++++++++++++++++++++++++++++++++++ ++++++++++++++++++ Preheat oven to 160ºC . Place ham, fat side down, in a shallow baking pan. Pour coke into pan until it is 1 cm deep. Bake 2 to 3 hours, or until ham can be easily pierced with a fork, basting with the Coca-Cola every 15 to 20 minutes. (Center of ham will read 60ºC on a meat thermometer when properly cooked.) Remove ham from the pan and cool. Cut away rind and fat with a sharp knife. Combine sugar, mustards, bread crumbs, and enough Coke to form a thick paste. Place ham on roasting rack in pan and pat all over with the paste. Add remaining coke to the bottom of the pan. Increase the temperature to 190ºC . and bake the ham 45 minutes longer, basting every 20 to 15 minutes until sugar-mustard paste has melted to a dark glaze. Let stand at room temperature 30 minutes before slicing.
