Preheat the oven to 375 degrees F.
Wash and dry the yams and cut off the ends. Peel, then cut into 1/2-inch thick circles. Place into a 12-by-9-inch casserole dish. Set aside.
In a medium pot, melt the butter over medium heat. Add the brown sugar and stir until thoroughly blended. Stir in the juice, cinnamon, vanilla and clove. Taste the mixture to make sure its sweet (to your liking) and pour over the yams.
Spread the preserves on top of the yams. Cover the dish with foil and place it in the oven until the yams are semi-tender, 40 minutes.
Remove the foil and bake to get a nice caramelization, 20 to 25 minutes.
Plate and serve hot. And don't forget to pour the sauce from the pan on top!
