About Spegesild
Spegesild is a much-loved Danish dish, celebrated above all for the distinctive flavour of pickled herring. The preparation involves steeping the fish in vinegar, onions and an assortment of spices that give the herring its unmistakable character. You will find it in traditional Danish restaurants and in countless homes, particularly as part of a festive lunch table or as a side dish for special occasions. Thanks to its unique balance of sharp, sweet and savoury notes, Spegesild is not only tasty but a genuine treat for the senses.
Ingredients (serves 1–2)
- 200 g pickled herring
- 1 small onion, sliced into rings
- 100 ml vinegar
- 50 g sugar
- 1 teaspoon mustard seeds
- 1 bay leaf
- A pinch of pepper
- Rye bread, to serve
Shopping for the ingredients
To make Spegesild you will want fresh, good-quality ingredients. Visit your local fishmonger or a well-stocked supermarket to find the best pickled herring available. Check that the fish has been properly cured, as the quality of the herring is decisive for the flavour of the finished dish. The choice of spices matters too; fresh mustard seeds and whole peppercorns deliver by far the most intense aroma.
Preparing the dish
Once you have bought your ingredients, you can begin preparing Spegesild. First slice the onions into thin rings and set them aside in a bowl. Then make the marinade by combining vinegar, sugar, mustard seeds, bay leaf and pepper in a small pan. Bring the mixture briefly to the boil so the sugar dissolves completely and the spices release their aromas into the liquid.
Step-by-step instructions
- Pour the prepared marinade into a bowl and add the onion rings.
- Cut the pickled herring into pieces and add them to the bowl as well.
- Mix everything thoroughly so that the herring and onions are evenly coated in the marinade.
- Leave the dish to steep in the fridge for at least 2 hours so the flavours can develop.
- Before serving, arrange on slices of crusty rye bread.
Gluten-free / lactose-free version
For a gluten-free Spegesild, use gluten-free rye-style bread or a similar alternative loaf. It is important to check the marinade ingredients carefully to be sure no gluten has slipped in, particularly in flavoured vinegars. As for lactose, the dish is naturally lactose-free, so there is nothing to worry about on that front. The choice of bread is the deciding factor in serving something both delicious and easy to tolerate.
Tips for vegans and vegetarians
For a vegan take on Spegesild, use pickled vegetables such as carrots, cucumber or beetroot. These can be steeped in the same spiced marinade as the herring to create a delicious plant-based snack. Do check that the marinade contains no animal products of any kind. With the right combination of spices and vegetables you can conjure up something every bit as tasty, much like the vegetable-forward Sodsuppe that also relies on a sweet-sour balance.
More tips and tricks
To make Spegesild even better, try experimenting with different spices such as dill or juniper berries. These lend the dish a particular character and can shift the flavour considerably. It is also worth letting the herring steep overnight, as the aromas develop far more fully with time. Another useful trick is to soak the onions in cold water for a while to soften their sharpness.
Adapting the recipe to your taste
The recipe for Spegesild is extremely adaptable. Depending on your own palate you can vary the quantities of sugar and vinegar to strike the perfect balance between sweetness and acidity. You might also try other fish, such as mackerel or sardines, to explore different flavours — a natural step on from the classic Sildemad. Experiment with different onions too, such as red onions or shallots, for a distinctive result.
Ingredient substitutions
If you cannot find pickled herring, other cured fish are widely available and work beautifully in Spegesild. Look for pickled sardines or cured salmon, both of which are equally delicious and bring their own character to the plate. In place of sugar you can also use honey or agave syrup for a more natural sweetness. Be creative and shape the recipe around your own preferences.
Drink pairing ideas
To round off the Spegesild experience, several drinks make excellent partners. A classic Danish beer, light and refreshing, complements the flavours perfectly, ideally with a small glass of ice-cold aquavit alongside. A dry white wine or a crisp sparkling wine also make ideal companions. Experiment with different drinks to find the perfect match for your menu.
Serving and presentation ideas
The presentation of Spegesild can be lifted with just a few small touches. Serve the dish on a handsome wooden board and garnish with fresh herbs to create an appealing contrast. Colourful plates help bring out the tones of the fish and onions, much as they do for an open sandwich spread of Smorrebrod. You can also arrange small portions in glasses for a modern, creative look that is sure to impress your guests.
A bit of history
Spegesild has a long history and is deeply rooted in Danish culture. The pickling of fish goes back to old traditions born of the simple need to preserve the catch through the winter. In the past Spegesild was a favourite along Denmark’s coastal regions, and today it is served in homes and at festive gatherings across the country. It stands as a symbol of Danish hospitality and of the love of maritime cooking that runs through Danish cuisine, passed down from one generation to the next.
