This mod does only one thing: it lets the vanilla grindstone handle enchanted golden apples. Put an enchanted golden apple into the grindstone, and it will be "washed" into a regular golden apple, while additionally returning 15 experience points.
The vanilla grindstone can only remove enchantments from items with durability or enchanted items. An enchanted golden apple has neither durability nor is it truly enchanted, so previously it couldn't be put in at all. With this mod installed, the grindstone recognizes it.
