The History of Christmas. "Candy canes".

During the 17th century, craftsmen created white sticks of candy in the shape of shephreds' crooks at the suggestion of the choirmaster at the Cologne Cathedral in Germany. The candy treats were given to children to keep them quiet during ceremonies at the living creche, or Nativity scene, and the custom of passing out the candy crooks at such ceremonies soon spread throughout Europe.
More recent explanations of the candy cane's symbolism hold that the color white represents Christ's purity, the red the blood he shed, and the presence of three red stripes the Holy Trinity. While factual evidence for these notions does not exist, they have become increasingly common and at times are even represented as fact. Regardless, the candy cane remains a favorite holiday treat and decoration.
