Honey is the only food on the planet that will not spoil or rot. It will do what some call turning to sugar. In reality honey is always honey. However, when left in a cool dark place for a long time it will do what is called "crystallize". When this happens, loosen the lid, boil some water, and sit the honey container in the hot water, turn off the heat and let it liquefy. It is then as good as it ever was. Never boil honey or put it in a microwave. To do so will kill the enzymes in the honey.
