the surface generously with the glaze. Put the roasting pan in the oven, with the top of the ham as close to the middle of the oven as size will allow. Bake for 1-2 hours, brushing the surface of the ham with remaining glaze and/or pan drippings every 20-30 minutes. It may also pay to rotate the pan once or twice for even browning. If the surface appears to be browning too fast, reduce the heat to 125degC. Place hot or warm ham on a platter and serve. Once cooled, refrigerate and store the leftovers as you would an unglazed ham.
