Method:

1. Combine all the glaze ingredients in a medium bowl, and stir or whisk to combine.
2. Carefully peel the skin from the ham and discard. Make 1cm deep cuts in a diamond pattern approximately 2-3cm apart all over the fat on the surface of the ham.
3. Place a clove at the intersection of each cut. Place the ham into a large baking dish alongside the orange slices, adding one cup of water.
4. Brush half the glaze all over the ham and bake in a hot (220 degree) oven for 15 minutes. Remove the ham, and brush with the remainder of the glaze. Bake for another 15 minutes.
5. Serve ham warm from the oven, or cold from the refrigerator.
