The honey in the jar has become cloudy /crystallized. Has it spoiled?

Honey is a natural beehive product. Its taste, texture and color change according to the seasons of the year and the geographical region. Pure honey may crystallize. This is a natural process and does not mean that the honey has deteriorated. Different types of honey have different tendencies to crystallize.

If you want to clear the honey, you can do this easily by placing the jar/bottle in a basin of hot (not boiling!) water.
