It is often served with crispbread, potatoes, onions, and sour cream.
While it may not be for everyone, those who enjoy surströmming consider it to be a true taste of Sweden.
The History and Origins of Swedish Fermented Fish: How it Became a National Treasure
The history of surströmming dates back to the 16th century, when fishermen in northern Sweden began preserving their catch using salt.
Over time, they discovered that allowing the fish to ferment before eating them improved their flavour and texture.

By the 19th century, surströmming had become a popular food throughout Sweden.
Today, it is considered a national treasure and is celebrated each year with a festival in the town of Skeppsmalen.

Surströmming is not just a food, it’s a cultural experience.
It’s a way for Swedes to connect with their heritage and traditions.

Controversy Surrounding Surströmming

Some people love it, while others can’t stand the smell.

How is Swedish Fermented Fish Made?
To make surströmming, fresh herring is first cleaned and gutted.
It is then layered with salt in large barrels and left to ferment for several months.
During this time, lactic acid bacteria break down the proteins and fats in the fish, creating a sour taste and strong aroma.
The Fermentation Process
The fermentation process is crucial to the creation of surströmming.
The fish must be left to ferment for several months, allowing the lactic acid bacteria to break down the proteins and fats in the fish.
This process creates the sour taste and strong aroma that surströmming is known for.
It is important to note that the fermentation process must be done properly to ensure the safety of the fish.
Improper fermentation can lead to food poisoning, so surströmming should only be consumed from a reputable source.
Canning and Selling
Once the fermentation process is complete, the fish are canned and sold.
The cans are airtight and often bulge due to the continued fermentation process.
This is a sign that the surströmming is fresh and ready to eat.
Surströmming should only be consumed from a reputable source, as improper fermentation can lead to food poisoning.

It is typically eaten outdoors due to its strong aroma, which can be overwhelming in enclosed spaces.
Consumption
When consuming surströmming, it is important to open the can outdoors or under water.
This is because the fermentation process creates gas that can cause the can to burst open and spray the surrounding area with a strong odour.
The cans are airtight and often bulge due to the continued fermentation process.
This is a sign that the surströmming is fresh and ready to eat.
Despite its strong aroma, surströmming is a beloved dish in Sweden and is often enjoyed at parties and gatherings.

The Proper Way to Open and Serve Surströmming: Avoiding the Infamous Smell
Surströmming is a Swedish delicacy that is notorious for its pungent smell.
To avoid offending your senses (and those around you), it’s important to open and serve the fish correctly.
Opening the Can
First, make sure to open the can outdoors or in a well-ventilated area.

Preparing the Fish
Next, remove the fish from the can and rinse it thoroughly with water.

Fermentation is a time-honoured method of preserving food that has many potential benefits beyond just making it last longer.
Here are a few reasons why fermentation is so popular:

Health Benefits
Fermented foods contain beneficial bacteria and enzymes that can improve digestion and boost immunity.
These microorganisms can help populate the gut with healthy bacteria, which can improve overall gut health and reduce the risk of certain diseases.
For example, kimchi is a fermented Korean dish that contains a variety of beneficial bacteria, including lactobacillus, which has been shown to have anti-inflammatory properties.
