Why does honey candy? April 18 2016, 0 Comments

It is coming to that time of year again, the cooler weather is finally upon us. And with it, comes a time when the honey will start to harden, known as crystallization, granulation or candying.

I often get asked why it candies; it is a quite a misunderstood phenomenon. Some people question whether this process means that it is an inferior product, poor quality or storage, or that it has been processed in some way. It is not. It is not off, it hasn't gone bad, so please do not chuck it out!!

Raw honey will candy over time. Some on-comb inside the hive (such as a clover or canola) and others take many, many years (such as Jarrah). Honey is dehydrated nectar which is ~80% water. The bees dehydrate it to between ~14-18% water, the rest of the honey being combination of fructose and glucose. The granulation of honey occurs when the saturation of glucose within the remaining water of the honey has occurred and there is an overabundance of glucose molecules in the honey that form crystals.

Because of the slightly different chemical compositions of different nectar, each honey is slightly different in the resulting balance of fructose and glucose. Those with a slightly higher glucose amount will candy faster. Raw honeys generally have a GI index of 35-40, whereas a homogenized/pasteurized (heated) honey will be about 60-65.

The quality of candied honey does not change, only the texture. Some people actually prefer the grainy, thicker texture of a candied honey. Interestingly, honey can also slowly change colour (generally darker) and taste over time as well, similar to how wine can change over time.

Candied honey can be much easier for things like cups of tea (non-drippy) and cooking (easier to measure for small quantities), however, if you prefer the liquid gold pop it in a pot of hot water or out in the sunshine on a warm day (with the lid well sealed). The ambient temperature over the day, at about 25 degrees or more, should bring it back to liquid by the time you get home from work! Do not put it in the microwave - it will be too hot, and if you don't gentle warm it, the candy process will be faster the second time around.
