HOW TO MAKE IT

Let's cook.

01

Boil the potatoes: Wash and peel the 4 medium potatoes. Cut them into quarters and place them in a pot of cold, salted water. Bring to a boil over high heat, then reduce to medium and simmer for 15-20 minutes, or until fork-tender. Drain and set aside.

02

Prepare the surströmming: Open the can of surströmming outdoors or in a well-ventilated area to minimize odor. Drain the brine from the herring. Carefully remove the fish, rinse them under cold running water, and remove the backbone and skin. Flake the flesh into small pieces.

03

Slice the red onion: Finely slice 1 medium red onion into thin rings or small dice.

04

Assemble the crispbread: Take 1 piece of tunnbröd and spread a thin layer of 1/2 cup sour cream over it.

05

Layer the ingredients: Place a few pieces of the flaked surströmming onto the sour cream. Add some boiled potato pieces and a sprinkle of sliced red onion. Finish with a pinch of 1/4 teaspoon freshly ground black pepper.

06

Serve immediately: Fold or roll the tunnbröd and serve immediately. Repeat for the remaining servings.

Chef's Tips

Opening the surströmming can underwater can help contain the strong odor. Serve with a cold beer or schnapps to complement the intense flavors.

Easy Substitutions

If tunnbröd is unavailable, use any thin, unsweetened flatbread or crispbread. Crème fraîche can be used instead of sour cream for a richer taste.

Storage & Reheating

Surströmming is best consumed immediately after opening. Leftover prepared crispbread rolls do not store well. Unopened cans should be stored in a cool, dark place.

Serving Suggestions

Serve with extra boiled potatoes and finely chopped dill on the side. Offer a variety of crispbreads for guests to choose from. A side of Västerbotten cheese, a strong Swedish hard cheese, can also be a good accompaniment. Pair with a cold lager or a shot of aquavit.

Common Mistakes

Opening the can indoors: The smell is very strong and can linger. Always open it outside or in a well-ventilated area. Not rinsing the fish: Rinsing helps to reduce the intensity of the flavor and saltiness. Using too much fish: For beginners, a small amount goes a long way. The flavor is potent. Not having enough accompaniments: The potatoes, onion, and sour cream are crucial for balancing the strong taste.

MORE TO KNOW
Surströmming is a traditional Swedish delicacy known for its pungent aroma and unique flavor. It's typically enjoyed outdoors during late summer. The key to appreciating surströmming is to embrace its strong character and pair it with the right accompaniments, which help to balance its saltiness and acidity. The ritual of opening the can and assembling the 'klämma' (sandwich) is as much a part of the experience as the taste itself. For first-timers, start with a small amount of fish and plenty of potatoes and onion.
