A pretty kettle of fish

“A newly opened can of surströmming has one of the most putrid food smells in the world.” I’ll explain. Surströmming is a traditional Swedish food that is prepared by marinating Baltic Sea herring in just enough salt to prevent it from rotting while it ferments in a can for up to a year. It is recommended that the can be opened out of doors, and that’s advice from people who like the stuff. Several international airlines have banned it. So it’s unsurprising that there are a lot of Italian restaurants in Sweden but not so many Swedish restaurants in Italy.
