The Surströmming Smell: A Deep Dive into the Aroma of Fermented Herring

Surströmming, a traditional Swedish delicacy, is infamous for its potent aroma. For many, the mere mention of surströmming smell evokes a mixture of intrigue and disgust. This blog post will explore what surströmming is, why its smell is so strong, and how it is perceived both in Sweden and globally.

What is Surströmming?

Surströmming is fermented herring that has been a staple in Swedish cuisine for centuries. The fish is caught during the spring, traditionally from the Baltic Sea, and then fermented in barrels for at least six months. The fermentation process is what gives surströmming its distinctive odor, which can be quite overwhelming.

The Fermentation Process

• Catching and Preparing the Fish: Herring is caught in the spring months when the fish are rich in fat.
• Fermentation: The herring is placed in a brine solution, where it ferments in a controlled environment. This process can take anywhere from six months to a year.
• Canning: After fermentation, the fish is canned with a bit of brine, and the can is sealed. It’s crucial to note that the fermentation process continues inside the can, which can make opening it a suspenseful experience.

Why Does Surströmming Smell So Strong?

The surströmming smell can be described as a combination of strong fishy notes, sharp ammonia, and a tangy sweetness. Here are a few reasons why its odor is so intense:

1. Chemical Reactions

The fermentation process breaks down proteins and fats into simpler compounds, releasing various gases. This includes:

• Hydrogen Sulfide: This compound is responsible for the rotten egg smell often associated with spoiled food.
• Ammonia: A byproduct of protein breakdown that contributes to the pungency.

2. Acidity

During fermentation, lactic acid bacteria thrive, producing lactic acid, which adds to the overall sourness of the smell, making it even more pronounced.

3. Storage and Preparation

The way surströmming is stored and prepared before consumption also affects its aroma. When a can is opened, the gases trapped inside are released, leading to a burst of smell that can be overwhelming.

How is Surströmming Consumed?

Despite its reputation, surströmming is enjoyed by many in Sweden and is often eaten in a traditional manner:

• Surströmmingsskiva: A surströmming party that typically includes thinly sliced flatbreads, potatoes, onions, and sour cream.
• Accompaniments: Fresh ingredients are crucial to balance the strong flavor and smell, creating a unique culinary experience.

Global Perception of Surströmming Smell

The surströmming smell has garnered a wide array of reactions across the globe:

• Cultural Acceptance: In Sweden, many people enjoy surströmming and consider it a delicacy, often serving it during special occasions.
• Outsider Reactions: For those unaccustomed to the smell, it can be quite off-putting. Many tourists and foreigners have captured their first experience of opening a can of surströmming, often highlighting the extreme reaction to the scent.

The Smell Challenge

It’s not uncommon for individuals to challenge themselves or friends to try surströmming as a rite of passage. These experiences, often shared on social media, showcase the intense reactions people have to the smell, creating a mix of humor and shock.

Conclusion

The surströmming smell is a unique aspect of this traditional Swedish dish, representing a culinary experience that is far from ordinary. While its aroma can be polarizing, surströmming remains a cherished cultural delicacy for many Swedes. If you’re feeling adventurous, consider trying it—but maybe do so outside or with some windows open!
