My informant is an American from Minnesota, who has ancestors from Czech republic and Sweden, back to 1880.
“The other thing that Sweden has, we have the kitchen witches. So hang a witch in the kitchen and they protect the kitchen. I still have kitchen witches, I have several. It’s like a little figurative witch on a broom, but they go in the kitchen, they’re called kitchen witches. They protect the food in the kitchen. So it’s a very Scandinavian sort of thing. It may have different looks in each family, but it has to be a witch, and you hang it in a kitchen. It keeps you up from messing up your kitchen.”
She is very proud of this specific object that they keep in Sweden culture, even though she has been immigrated to US for a long time. I think it’s very lovely that in many Scandinavian cultures they believe in magic and magical creatures, and sometimes they really work when you believe in them. In this case if you do believe in the kitchen witches can protect you from messing up your kitchen, and hang them there, you may really become more cautious while cooking.
