Estimated Reading Time: 9 minutes.

Surströmming is a traditional Swedish fermented herring known for its exceptionally pungent aroma and complex flavor profile. Produced by lightly salting Baltic herring and fermenting it for several months, surströmming has long been both a cultural staple and a culinary curiosity. This article provides an in-depth exploration of surströmming’s sensory characteristics, a scientific flavor analysis, its culinary applications, nutritional insights, and practical tips for selection and storage.

What does Surströmming taste like?

Taste, Aroma, Texture, and Visual Appearance of Surströmming

Taste:
Surströmming delivers a robust and tangy flavor that is surprisingly nuanced beneath its intense aroma.

  • Flavor Description: Upon tasting, you encounter a sharp sourness from the lactic acid produced during fermentation, balanced by a subtle brininess and an underlying sweetness that emerges as the fish mellows. The flavor profile is complex—initially bracing, yet layered with hints of salt, tang, and a mild umami depth.

Aroma:
The aroma of surströmming is famously potent and polarizing.

  • Aromatic Description: Its smell is often described as intensely sour and ammonia-like, a result of the fermentation process. Despite its formidable odor, the scent hints at the traditional, time-honored methods used to preserve the herring, evoking the rustic charm of Scandinavian coastal cuisine.

Texture:
Texture plays an essential role in the overall surströmming experience.

  • Texture Description: The fermented herring is soft yet slightly firm, with a delicate flakiness that contrasts with the sticky brine. This texture, combined with the fish’s tenderness, makes it adaptable to various culinary applications despite its strong flavor.

Visual Appearance:
Surströmming is visually unassuming yet steeped in tradition.

  • Visual Description: The herring typically appears in a muted, silvery-gray to light brown tone, often presented in a sealed tin. The fish may show slight translucence, indicating the prolonged fermentation process, and is usually served with complementary accompaniments that add visual contrast.

2. In-depth Flavor Analysis of Surströmming

The unique flavor of surströmming is the product of a carefully controlled fermentation process and the interaction of several key factors:

  • Fermentation Process:
    Surströmming is made by lightly salting Baltic herring and allowing it to ferment for several months. During fermentation, lactic acid bacteria convert the natural sugars in the fish into lactic acid, producing a pronounced sour taste that forms the backbone of its flavor profile.

  • Balancing Brininess and Sourness:
    The fermentation not only intensifies the sour notes but also enhances the inherent saltiness of the fish. This balance between tangy acidity and briny flavor creates a complex, multi-dimensional taste that can be surprisingly refined once the initial shock of the aroma is overcome.

  • Development of Umami:
    As proteins break down during fermentation, free amino acids and peptides accumulate, contributing to a mild umami flavor. This savory depth adds richness and complexity to surströmming, transforming it from a simple fermented fish into a food with a layered taste experience.

  • Impact of Aging:
    The duration of fermentation influences the intensity of both flavor and aroma. Longer fermentation periods generally result in a stronger, more pronounced sourness and aroma, while shorter periods yield a milder, more balanced flavor profile.

Culinary Applications of Surströmming

  • Primary Uses:
    Traditionally served as a main dish in Swedish cuisine, surströmming is often accompanied by flatbread (tunnbröd), boiled potatoes, and red onions to balance its intense flavor.

  • Popular Applications:

    • Traditional Platters: Serve with crisp flatbread, boiled potatoes, and a squeeze of lemon to add brightness and counterbalance the sourness.
    • Sandwiches and Wraps: Incorporate surströmming into sandwiches for a bold, acquired taste that pairs well with creamy spreads and fresh vegetables.
    • Fusion Dishes: Chefs are experimenting with surströmming in contemporary recipes, such as in seafood salads or as a flavor accent in innovative canapés.

  • Ideal Pairings:
    The strong flavor of surströmming is complemented by mild, starchy foods like potatoes and bread, as well as acidic components like lemon juice and fresh red onions, which help balance and refresh the palate.

Selection and Storage of Surströmming

  • Selecting Surströmming:
    When purchasing surströmming, choose products from reputable sources that follow traditional fermentation methods. The fish should be well-fermented, with a consistent sourness and a potent but balanced aroma.
  • Storage Recommendations:
    Store surströmming in a cool, dark place before opening. Once opened, it should be kept refrigerated and consumed within a few days to maintain its optimal flavor and texture. Proper handling is essential due to its strong odor, so sealed packaging is recommended.
