Preheat oven to 325 F.
Make sure that the ham is completely thawed.
Decorate the ham with pineapples & cherries, using the toothpicks to hold everything in place.
In a large measuring cup or bowl, combine the pineapple juice, cherry juice, brown sugar, mustard, honey, ginger, clove, nutmeg, and cinnamon.
Stir everything, then sprinkle in the cornstarch.
Whisk everything until lump free, then transfer the sauce/glaze to a saucepan.
Bring the sauce to a boil over medium-high heat and whisk constantly.
Let boil for about 3-5 minutes, then turn the heat off.
Pour the glaze all over the ham.
Bake the ham, uncovered, for 30 minutes.
Remove the ham from the oven and baste and extra glaze and pan juices.
Place back in the oven for 20-30 minutes (still uncovered).
Remove from the oven and let the ham sit for about 15 minutes.
Serve & enjoy!
