What is crystallization?
Crystallization or granulation is a natural process that occurs in honey which aids its preservation. It does not indicate spoilage. Honey is a supersaturated sugar solution out of which the glucose tends to crystallize. Some honeys crystallize quicker than others, depending on the nectar source.
My honey has crystallized. Do I need to throw it away?
No. Crystallization can be reversed by heating. Place the honey container in a warm water bath for a period of time to return the crystals to liquid.
