Any cooked ham can be used but the cherry sauce goes particularly well with Virginia ham with its particular flavor.
Heat the oven to 350º F. Wrap the ham in foil and warm in the oven for 30 minutes.
In a saucepan, mix together the brown sugar, corn starch, cinnamon, apple juice and vinegar.
Heat, stirring frequently, until the sauce boils and thickens. Let it boil for 2 minutes.
Stir in the cherries and cook 4-5 minutes more, or until the cherries are heated through.
Remove the ham from the oven and distribute on the plates. Ladle a little cherry sauce over the ham and serve.
