oh, I would like that! Never saw it on any Swedish restaurant menus while I was there or I certainly would have tried it. Perhaps it is not the sort of thing they serve at restaurants? I must visit your mother ASAP.
(While in Sweden, I recall eating a ton of lovely fish, prepared in all kinds of ways, and very good rye breads. Also, I had a saffron/honey ice cream in Visby on Gotland Island that was to die for. I've never found it anywhere else -- I'd go back just for that.)
Despite much experience with high-brow foodie food (which I also like, btw), I retain a taste for hearty peasant food. I suspect it's all the peasant blood in my veins, on all four sides.
That said, I'll eat almost anything that hasn't gone bad and has been cooked properly. It makes traveling a lot easier! And I've yet to strike a national dish I didn't like. I am prone, when faced with a menu in another language, to just point at random and see what arrives.
