The Fermentation Process

Surströmming is made from Baltic Sea herring, which is caught in the spring and then fermented. The process involves:

  1. Catching and Storing: Herring is harvested and stored in barrels.
  2. Salt Brining: A high concentration of salt is used, which helps to prevent spoilage while allowing fermentation to start.
  3. Fermentation: Over a period of several months, the fish undergoes anaerobic fermentation, leading to the development of its unique flavors and smells.

This fermentation process is crucial, as it breaks down proteins into simpler compounds, resulting in a variety of volatile organic compounds (VOCs) that contribute to the distinctive odor.

Cultural Significance of Surströmming

Surströmming is more than just food; it’s a tradition in Sweden. Consumed mainly during the early fall, it is often served with flatbreads, potatoes, and onions. Surströmming is celebrated in gatherings known as “surströmmingsskiva,” where enthusiasts share the experience of eating this delicacy.

What Contributes to the Smell?

The smell of surströmming can be attributed to several factors:

  • Ammonia: One of the primary compounds produced during fermentation is ammonia, which has a sharp, pungent odor.
  • Trimethylamine: This compound, often associated with fishy smells, is released as the fish breaks down.
  • Other VOCs: The fermentation creates a blend of other volatile compounds, including sulfur compounds that can have a strong stench.

The combination of these compounds results in an aroma that many find unbearable. Interestingly, this smell is often described as akin to rotten eggs or strong cheese, but for enthusiasts, it signals flavor richness.

How to Enjoy Surströmming

For those brave enough to give surströmming a try, here are some tips to enhance the experience:

  • Choose the Right Location: Many people recommend enjoying surströmming outdoors, as the smell can be overwhelming in enclosed spaces.
  • Pairing: Serve with traditional accompaniments like thinly sliced onion, boiled potatoes, and flatbreads to balance the strong flavors.
  • Breathe Deeply: Before diving in, take a moment to appreciate the unique aroma—many enthusiasts say this enhances the flavors.
  • Share the Experience: Surströmming is best enjoyed with friends or family, making it a fun and memorable event.

Conclusion

The question of why does surströmming smell so bad can largely be answered by understanding the fermentation process and the compounds produced during it. While its odor may deter some, for others, surströmming is a beloved delicacy steeped in tradition. If you’re feeling adventurous, consider trying this unique dish, and who knows—you may just develop a taste for it!
