A Bowl of Porridge

You have to serve a bowl of rice pudding to the Tomte during Christmas. If you neglect to do so anything can happen. I didn't want to take any chances so I left a bowl on the veranda. From Wikipedia: One was also required to please the spirit with gifts (see Blót) – a particular gift was a bowl of porridge on Christmas night. If the tomte was not given his payment, he would leave the farm or house, or engage in mischief such as tying the cows' tails together in the barn, turning objects upside-down, and breaking things (like a troll). The tomte liked his porridge with a pat of butter on the top. In an often retold story, a farmer put the butter underneath the porridge. When the tomte of his farmstead found that the butter was missing, he was filled with rage and killed the cow resting in the barn. But, as he thus became hungry, he went back to his porridge and ate it, and so found the butter at the bottom of the bowl. Full of grief, he then hurried to search the lands to find another farmer with an identical cow, and replaced the former with the latter.
