1 cup brown sugar
2 tbsp water
1/4 cup butter
3-4 tbsp cider vinegar
1 tsp dry mustard

Melt butter in saucepan, add brown sugar and water and bring to a boil for about 1 minute or until sugar is melted and no longer grainy (will be very thick). Remove from heat and add cider vinegar and dry mustard. Brush over ham during last half hour of cooking time (uncover ham) and keep repeating as the mixture cools and thickens until it is all used on the ham. Can add cloves to sauce.

Great on a spiral cut ham, I like the shank portion best...
when I get a spiral cut ham, I use the provided glaze packet, and add the vinegar & mustard after following the directions, and let it cool for maybe 10 minutes (to thicken) before brushing on the ham...

It's not for a Honey Baked Ham Store Spiral cut... I like them just as they are from the store...
