Yes it is true, it is a Swedish tradition to eat fermented herring… Sounds weird but it is good (a very special taste though). Most are put off by the smell when the can is opened, however it smells worse than it tastes.
The “surströmming” (fermented herring) party is always in the early fall/autumn. And from what I’ve heard it all started a long time ago with a barrel of herring not being salted enough. That barrel started to ferment while being stored, and since people were poor they couldn’t just throw it out, they ate it. And those who liked it started to produce it every year when they fished the herring. And still the year’s new “surströmming” comes in August. I have also heard that fewer seem to eat the delicacy, but I can’t understand why… Also I saw on YouTube a clip with some Americans trying this fish, and their reaction was hilarious to say the least…. I guess it’s an acquired taste 😊👍 and for most it’s also an opportunity to drink a bit / or lot…..
To the “surströmming” you eat boiled potatoes, raw chopped onions, flat bread (the type I baked in a previous post this summer) with butter. Some like a bit of sour cream on as well (I think that’s just weird though).
If you ever have the chance, try it!
