Sour Cherry Sauce for Ham

This is a most excellent fruit sauce for ham. My mom's been serving it to us every holiday ham dinner since I can remember, and the tart sweetness of the sauce combined with the salty sweetness of the ham is heavenly. I'd love to give you her exact recipe, but I can't, because she doesn't have one. Here's the basic idea, though, thanks again to the Better Homes and Gardens cookbook.

A jar of sour cherries, canned by Mopsy, pitted and drained (Okay, I guess the cherries don't have to come from my mom)
3 tbsp. brown sugar
4 tsp. cornstarch
1/4 tsp. ground cinnamon
dash of ground cloves
1 cup apple juice
1 tablespoon vinegar
a few drops of red food coloring, opt.

In a medium saucepan, combine brown sugar, cornstarch, cinnamon, and cloves. Stir in apple juice, vinegar, and, if desired, food coloring. Cook and stir over medium heat until thickened and bubbly. Cook and stir for 2 minutes more. Stir in as many of the drained cherries as looks right (the cookbook recommends 16 oz.). Heat through. Serve warm spooned over ham. Makes 2 and 1/4 cups sauce.
