Yule log

A Yule log is a large and extremely hard log which is burned in the hearth as a part of traditional Yule or Christmas celebrations in several European cultures. It may also be associated with the Winter Solstice festival or the Twelve Days of Christmas, Christmas Eve, Christmas Day, or Twelfth Night.

The expression Yule log has also come to refer to log-shaped Christmas cakes, also known as chocolate logs or Bûche de Noël. The Yule log is related to other Christmas and Yuletide traditions such as the Ashen faggot.[1]
