you are so right. herring is the grossest thing ever. don't even try it. you will probably throw up. and we have something even more gross called surströming, have you heard about it? it's route herrings. some crazy swedish people appreciate it, i dont recomend it at all.
however, we have some swedish food that is really good. we always have crayfish parties in the end of summer where we eat crayfish, bread, cheese, and, mayonnaise. i know it sounds like a really bad combination but it's pretty good. we also drink a lot of alcohol at these parties. it's a tradition. but alcohol is expensive in sweden though. there are only one store that is allowed to sell alcohol and it's owned by the government. i think it's a combination between get profit and control the swedes way to drink. one beer costs somewhere between 3-5 dollars at that store and around 7 dollars if you buy it at a night club.
do you have any american food that grosses you out? i get sick just thinking about a peanut butter and jelly sandwich.
take care, and don't eat too many hamburgers
