Some weeks ago I cooked Flying Jacob (Swedish: Flygande Jacob or Flygande Jakob) at my friends Anders' & Amy's place for some lovely dinner guests (pictures at flickr). We had a great time, and at the end of the night I got that greatest of compliments from Marc, he asked for the recipe (he wasn't just being nice, I have since heard that he has actually even used it cooking for his friends, who also loved it).
I think this dish was "invented" in the 70s by a Swedish chef (if anyone knows the story, please contact me). Have since I wrote this found the answer, read full post and scroll down to have the secret revealed!

Usually it is served as a kids' dish, the savoury taste and the mix of sweet, salty and creamy makes it an easy sell I guess (and the pink color is a bit different, which I think also goes down well with our younger co-inhabitants of Earth). Every household in Sweden seems to have their own version of this dish, but this is mine.
