In the bottom left of the world map there is a wishing well. By visiting it, it looks like you can throw items into the well, and presumably, make a wish...
What are the outcomes of throwing items in the wishing well?
candy - health regen, will increase every time you heal. Better not to use it often.
chocolate bar - weapon enchantments
lollipops - convert two lollipops to one candy
also you will get "pain au chocolate" later, with it you can boost your stats (HP/DMG/Cooldowns)
Also even there is no item in your inventory that can be enchanted, the chocolate bar you throw will not be in vain. When you get an item/items that can be enchanted and go to wishing well it will automatically show enchanting option for the chocolate bar you threw before.
In addition to rlex's answer, one may also throw in pains au chocolat. Throwing in pains au chocolat gives you a choice between More Health, More Power and More Magic.
