Crystallized honey is a common thing because raw honey crystallizes. Most grocery store honey does not crystallize because it is not real honey or because it is not raw honey. Crystallized honey is also really easy to ‘fix’.
This is our crystallized honey. Honey crystallizes because honey contains lots of natural sugar. The overabundance of sugar makes honey unstable especially when it is cold. Thus, it is natural for honey to crystallize since it is an over-saturated sugar solution. When glucose crystallizes, it separates from water and takes the form of tiny crystals. Therefore it crystallizes like seen below.
This is a picture of honey that is not crystallized.
Here is how we uncrystallized our honey. We put a heating pad underneath the bottles of honey. Some of the honey is crystallized only on the bottom others are fully crystallized throughout the jars.
After we put the honey on a heating pad, we covered them with towels and closed the cooler.
Other methods of uncrystallizing honey is putting it in a warm water bath using either a crockpot or a double boiler that stays under 120 degrees Fahrenheit. If you put it over 120 degrees, you loss all the nutritional value of honey.
