1gammon hamsmoked and/or cooked, approx. 5-6 kg, with bone in
454grjar good quality orange marmaladeI used Chivers extra fruity marmalade
300grlight muscovado sugar
jar whole cloves
Heat oven to 200C. Put the ham in a roasting tin on a trivet. If you don't have one, a few halved carrots will do the trick as well. Mix the marmalade with the sugar and 50 ml of water in a small pan, bring to the boil and then set aside and leave to cool.
Score lines into the fat of the ham with a knife to make large diamond shapes, with the lines about 4 cm apart. Brush a third of the marmalade glaze over the joint, really pushing it into the creases and cuts. Now stud the ham with the cloves by poking a clove into the corner of each diamond.
Roast the ham, uncovered, for 45-50 minutes, brushing with the remaining glaze a few times during cooking, until caramelised and delicious. Carve hot or cold.
