I heard the Polish version mentioned on a game show just the other day. They said that they were deep fried, and served with mustard. This sounds very much like them.
Contestant got the question wrong. She thought they were Swedish, but swedish arent deep fried. She should have paid more attention to the question. HA HA.. The audience also got it wrong.
But your recipe looks good, and I am going to try them fried like that.
