Do not throw it out. Honey is the only natural food in the world that will NEVER go bad. All honey will crystalize over a period of time. All you have to do is warm it up and it will liquify again.
Look up the history of honey and you will find it never spoils or goes rancid.
(Just a little history here, archaeologists (sp) dug up remains of Egyptians and found honey that was still good.)
