A fish so smelly that it started a whole challenge! I thought that the videos were nothing more than just click bait. But boy, was I wrong.
One sniff of the pungent smell and there was only one question in my mind, How is this something humans could eat?! You’re about to find out.
Surströmming: World’s Smelliest Fish
Surströmming is an infamous Swedish delicacy made of fermented Baltic sea herring. The Fermented Baltic herring, has been of staple of Northern Swedish cuisine since the 16th century. The spawning fish are caught between Sweden and Finland during spring.
The fermentation process gives surströmming its characteristic smell and taste, which is often described as “rotten” or “putrid,” which is why it has gained the title of the world’s smelliest fish.
The Swedish Surströmming Stinky Fish Challenge
Truth be told, it is fun and entertaining to see people get so shocked and surprised after opening a can of surströmming.
Some find the slightly acidic nature of the dish a little too much, but some like it when they get past the initial shock. Well, as the Swedes say, “It’s an acquired taste”.
What Does Surströmming Taste Like?
It’s intensely salty, with the tang of fermentation and a deep, underlying fish flavor. It offers a rich umami flavor derived from the fermentation process.
Why Is It So Smelly?
The smell of surströmming is primarily due to the breakdown of proteins and fats in the fish during fermentation.
The fermentation process produces various compounds, including ammonia and sulfur, which contribute to its strong aroma.
The Production Process

The production of surströmming involves several steps that contribute to its infamous pungent odor:
- Harvesting the Herring: Herring is caught during the spring spawning season.
- Salting: After being caught the fish is salted to prevent spoilage.
- Fermentation: Then the fish is placed in barrels and covered with enough salt to cover the fins where it ferments for at least eight weeks.
- Packaging: The fermented herring is canned in a container made of tin, often under pressure, which can cause the cans to bulge due to gas buildup.
The Proper Way To Enjoy Surströmming
Like with many food challenges online, the correct way of consuming the said item is often ignored to get exaggerated reactions from both the viewers and the participant.
You’re not here for that, right? You actually want to enjoy surströmming like a local. Here’s how to do it.
Surströmming should always be enjoyed with accompaniments to balance its strong flavor:
- Onions: Chopped onions can help cut through the pungency.
- Potatoes: Surströmming mixed with mashed potatoes can enhance the overall flavor of the dish.
- Sour Cream: A dollop of sour cream can add creaminess.
- Snaps: Adding just a tad bit of surströmming can take your Swedish liquor to the next level.
- Tortillas or Flatbread: These serve as a base for the fish. With soft bread, it’s possible to make a roll, and with hard bread it can be eaten as a sandwich
Two Words Of Caution
Before you head to your local Swedish market to buy surströmming keep these two things in mind:
- Cautious Sampling: If you’re new to surströmming, start with a small amount to gauge your tolerance for its flavor.
- Cautious While Opening: It is often recommended to open a can of surströmming outdoors to avoid overwhelming indoor spaces with the stinky smell.
