National Dish Iceland: Graflax with Mustard Sauce (Recipe)
In this article
Meet Graflax with Mustard Sauce, one of Iceland’s most elegant contributions to the Nordic table. Silky cured salmon is buried in salt, sugar and armfuls of fresh dill, then left to work its quiet magic in the fridge for a day or two. Sliced wafer-thin and spooned over with a sweet-sharp mustard sauce, it needs almost no cooking at all — just good fish, a little patience and a sharp knife.
About Graflax with Mustard Sauce
The traditional Icelandic dish Graflax is not only a genuine treat but also a fine showcase for Nordic cooking. It consists of marinated salmon prepared with a balanced mixture of salt, sugar and assorted spices. This method of curing keeps the salmon tender and full of subtle layers of flavour. Graflax is often served with a punchy mustard sauce, which gives the dish an extra fresh kick. It sits comfortably alongside other classics of Icelandic cuisine such as Reyktur Lax.
Ingredients (serves 1–2)
- 250 g fresh salmon, filleted
- 50 g sea salt
- 50 g sugar
- 1 bunch dill, chopped
- 1 tsp black peppercorns, crushed
- 2 tbsp mustard
- 1 tbsp honey
- 2 tbsp olive oil
Shopping for the ingredients
To make an authentic graflax, the choice of ingredients matters enormously. Fresh salmon, ideally from a sustainable fishery, is the heart of the dish. Look closely at the quality and freshness of the fish when you buy it, as this guarantees the best possible flavour. The remaining ingredients are available in most supermarkets and together offer a varied combination of aromas that round the dish off perfectly.
Preparing the dish
Preparing graflax is relatively straightforward and takes only a few steps. First you make the cure, which consists of salt, sugar, dill and pepper. This mixture is spread evenly over the salmon before the fillet is wrapped in cling film. It is important to keep the salmon in the fridge throughout the curing time so the flavours penetrate properly and the texture of the fish improves.
Step-by-step instructions
- Lay the salmon on a clean work surface and make sure no bones remain.
- Combine the salt, sugar, dill and pepper thoroughly and spread the mixture evenly over the salmon.
- Wrap the salmon in cling film and leave it to cure in the fridge for 24–48 hours.
- Once cured, rinse the salmon and cut it into thin slices.
- For the mustard sauce, mix the mustard, honey and olive oil well and adjust to taste.
- Arrange the finished graflax on a plate and serve with the mustard sauce.
Gluten-free / lactose-free version
Graflax is naturally gluten-free and lactose-free, which makes it an excellent choice for anyone with allergies or intolerances. Simply check that the mustard and honey products you use are also free from gluten and lactose. There are plenty of alternatives on the market designed specifically for sensitive stomachs. That way, people with particular dietary needs can enjoy this delicious graflax too.
Tips for vegans and vegetarians
Although graflax is traditionally made from salmon, there are creative ways to put together a vegan or vegetarian version. Carrot “salmon” makes an intriguing alternative, with the carrots cured and prepared in exactly the same way as the fish. This inventive imitation delivers not only the texture but also the chance to capture those maritime aromas. Vegans and vegetarians can therefore share in the flavours that make graflax so distinctive.
More tips and tricks
A successful graflax needs high-quality ingredients, but a few small tricks help you reach the perfect result. Twenty-four hours is a reliable benchmark for the curing time, though the longer the salmon cures, the more intense the flavour becomes. When slicing the salmon, use a very sharp knife to achieve clean, even slices. Details like these make a decisive difference to both presentation and taste.
Adapting the recipe to your taste
The wonderful thing about graflax is its versatility. Depending on your own preferences you can adjust the spices in the cure or add extra herbs such as thyme or parsley. The level of sweetness in the mustard sauce can be personalised too, according to whether you like it sweeter or sharper. Adjustments like these let everyone create their own perfect graflax — much as you might with a creamier Graflax with Dill Sauce.
Ingredient substitutions
If you do not have certain ingredients to hand, there are plenty of alternatives you can use in your graflax. Instead of fresh dill, for example, you might reach for other herbs such as tarragon or chives. For the mustard sauce, pick whichever style of mustard suits you best — sweet, hot, or even one made with beer. Substitutions like these broaden the flavour profile and open up new taste experiences.
Drink pairing ideas
When serving graflax, do not overlook the right drinks. A well-chilled Sauvignon Blanc or a lively prosecco pairs beautifully with the fresh aromas of the dish. If you prefer alcohol-free options, a freshly pressed citrus drink or a raspberry smoothie complements the flavours nicely. These combinations contribute to a thoroughly satisfying meal.
Serving and presentation ideas
The presentation of your graflax is decisive for that first impression. Serve the cured salmon on an elegant wooden board or a handsome porcelain plate to give the dish a special touch. Garnish it with fresh herbs and a slice of lemon for visual appeal. Small details like these can improve the whole dining experience considerably and impress your guests. A basket of Rugbraud alongside completes the spread.
A bit of history
Graflax has its roots in Icelandic tradition, where preserving fish was a pressing concern. Northern peoples developed this method of curing and marinating so that salmon could be enjoyed over a long period without spoiling. Today graflax is popular not only in Iceland but throughout many northern European countries. The dish embodies the maritime culture and culinary traditions that make Iceland so singular — the same instinct for preservation you find in Hardfiskur.
