Why do norwegins put a bowl of rice pudding out for the barn elf?

Norwegians do not put a bowl of rice pudding out for a barn elf. This is a common misconception based on the character of Nisse, a mythological creature known for causing mischief in Norwegian folklore. Traditionally, Nisse is offered a bowl of porridge, not rice pudding, as an offering to keep him happy and prevent him from playing pranks on the household.
