Honey and Crystallization. Crystallization is a completely natural process and occurs with all raw honey. The speed and size of the crystallization depends on variations in the balance of sugars, ambient temperature and to some extent water content If your honey is set hard, you can loosen it up by placing it in a pan of hand hot water, (and repeat as necessary) using a spoon placed in hot water first and of course storing it in a sunny/warm place in the house.
