Christmas pickle
The Christmas pickle is a Christmas tradition in the United States. A decoration in the shape of a pickle is hidden on a Christmas tree, with the finder receiving either a reward or good fortune for the following year. There are a number of different origin stories attributed to the tradition, but it was primarily thought to have originated in Germany. This has since been disproved and is now thought to be an American tradition from the late 19th century.
