I wonder what it smells like. Can someone tell me what it smells like?

Exactly.. There are way too many videos on youtube where people eat it by itself and all question the sanity of Swedes.. :P I eat it with crisp bread, potatoes, sour cream and red onion. Its really good! We also don't eat it inside because of the smell and usually open the can quite a distance from where we sit down to eat.

Yes my friend told me about it, and warned me against doing it inside because the smell would linger for ages (I will try it one day)
