You can have my portion of lutfisk and also surströmming but you can push all the herring and gravlax you don’t want over to me. Surprisingly (to us in the US) perhaps, pork, not herring or salmon, was the most important meat on the traditional Swedish table according to what I’ve read.
I guess the Wikioracle article on Swedish cuisine is as good a starting point as any and there are lots of other resources and guides that come up with Google.
I follow Anne’s Food. She hasn’t been posting as much lately and doesn’t cook much Swedish food, actually, but she has a Stockholm guide section that may be of interest.
I would really hope to find some reindeer dishes but I understand that’s much more common in the north.
ETA: Re: the mashed potatoes and rak sallad on a hot dog - my 3rd cousin in Stockholm says serving mashed potatoes with sausage is traditional so it’s a no-brainer to a Swede to put mashed potatoes on a sausage sandwich. I like it better than crushed potato chips which is so popular in some cultures. But the rak sallad is like ketchup in America - some love it, some are refuse it.
