In a food processor or blender, puree the apricot preserves. Heat the puree in a small saucepan and blend in the mustard until smooth. Spread the glaze over your ham before baking.
When the ham is done baking, turn on the broiler. Then leave the oven door open and let the glaze brown for about 45 seconds.
