In Scandinavia, there is a Solstice Eve tradition to leave a bowl of porridge outside for the Nisse, the little land spirit person who helps out with the work on the farm and serves as a guardian to the family and the animals. According to what I learned, it was very important to put a pat of butter on top. The Nisse can be troublesome if not properly respected.
There are little guardian spirit people traditions in many other places, too. Scots and English call them Brownies, there is the German Kobold, and I have learned about Wabanaki little people called Wonakomehsisok who were said to be spirit helpers who lived among rocks. The Wolastoqiyik spoke of Kiwolatomuhsisok, who were said to help people secretly at night, and have a breath that smells like mold.
All that said, on Solstice Eve, I put out a bowl of porridge in the back yard, with a big pat of butter on top, (which by the way is how I like my own porridge) as an offering for any little land spirits on our land that might appreciate it. Perhaps it might be one more way to deepen our relationship with this land, to make friends with the spirits who protect and cherish the land.
Sadly, the next morning, it was still there, and frozen–but I moved it from the middle of the yard to the way back, where more wild creatures tend to go by. (We’ve put other food offerings out there in a similar way, and they disappear.) When I returned from my walk, I was happy to see a crow back there at the bowl, pecking at it with their beak. They are also guardians of this land.
Later, I discovered that the crow flew off with the pat of butter but left the porridge. So I guess that our land spirits might not like porridge–which is after all a very European food tradition. We’ll have to keep experimenting with other foods, to see what they prefer. Still, I was happy to give a gift to the crow.
