Place all ingredients into a deep bowl or large measuring cup and blend with a stick blender. Adjust to taste and store in an airtight container in the fridge.
When ready to use, heat slightly to make glaze pourable for ease of coverage of the ham during the last 30-45 minutes of heating. Brush or pour glaze over ham 2-3 times to develop a nice crusty exterior. Save some to pass at the table for guests who want more sauce.
