Salmon cured for three days under salt, sugar, dill and crushed white pepper until silken and lightly translucent, served sliced wafer-thin with the classic sweet-sharp Swedish mustard sauce.
Gravlax is the great Swedish contribution to the world's curing traditions and one of the most elegant ways human beings have devised to preserve fresh fish. The name means 'buried salmon' and recalls its medieval origins, when fjord fishermen would salt fresh salmon, layer it with dill and birch bark, and bury it in cool sand or rocky earth to ferment slightly over weeks — a method that preserved fish for the long Nordic winter. The modern method, perfected in 19th-century Swedish kitchens, is gentler: a side of very fresh fatty salmon (with skin on) is laid flesh-side-up, covered in a thick blanket of coarse sea salt, white sugar, crushed white peppercorns and a forest of chopped dill, then wrapped tightly and weighted in the refrigerator for 48 to 72 hours. As it sits, salt and sugar draw moisture from the flesh, the dill perfumes it, and the salmon transforms — its raw glassy texture firming into something between sashimi and smoked salmon, silken on the tongue with a clean briny sweetness and a fresh herbal back-note. To serve, the cure is wiped off and the salmon is sliced wafer-thin on a sharp angle, the way a Stockholm waiter does it. Always alongside is hovmästarsås — 'maître d's sauce' — a thick, glossy emulsion of strong Swedish mustard, sugar, vinegar, neutral oil and chopped dill, sweet-sharp and creamy, the indispensable companion. Eaten on dark rye or knäckebröd at Easter, midsummer, Christmas and any smörgåsbord between, gravlax is Sweden's most beloved curing tradition.

Run your fingers along the salmon to find any remaining pin bones and pull them out with tweezers. Pat the fish very dry with paper towels — moisture interferes with the cure. Trim any thin belly flap that is much thinner than the main body.
Previously-frozen salmon (frozen at least 24 hours below -20°C) is safest for cured preparations.
In a bowl, combine the salt, sugar and crushed white peppercorns. Stir well.
Lay a large sheet of plastic wrap on the counter. Sprinkle a third of the cure on it. Lay salmon skin-side-down on the cure. Cover the flesh side with the remaining cure mixture, pressing it gently to adhere. Top with a thick, even blanket of all the chopped dill — every part of the flesh must be covered.
Wrap the salmon tightly in 2–3 layers of plastic, ending skin-side-down. Place in a glass or ceramic dish to catch leakage. Top with a small board or plate and weight with cans (about 1 kg total). Refrigerate.
The weight presses out liquid evenly and gives the firm dense texture; skipping it gives a softer, juicier cure.
Turn the parcel over every 12 hours so the cure penetrates both sides evenly. The salmon is ready when the flesh is firm to the touch, deeply opaque coral-pink (not raw red), and slightly translucent at the edges. 48 hours gives a delicate, slightly soft cure; 72 hours gives a firmer, more intensely flavoured one.
Unwrap, scrape off all the dill and cure with the back of a knife, then rinse briefly under cold water and pat very dry. The flesh should be silken and faintly glossy. Re-apply a small handful of fresh chopped dill across the surface and press to adhere.
In a small bowl, whisk mustard, vinegar and sugar together until smooth. Whisking constantly with one hand, drizzle the oil in a thin stream with the other — it should emulsify into a thick, glossy, mayonnaise-like sauce. Stir in the chopped dill and a pinch of salt. Taste — should be sweet, sharp, mustardy, thick enough to coat the back of a spoon.
Lay the salmon skin-side-down on a board. With a long sharp knife held at about 20°, slice the flesh into wafer-thin slices across the grain, leaving the skin behind. Arrange slices slightly overlapping on a platter, with the mustard sauce in a small bowl, lemon wedges, capers, red onion slivers, and a basket of dark rye bread for guests to assemble their own bites.
Use only sushi-grade or previously-frozen salmon for the cure; this protects against parasites since the fish is not cooked.
Equal weights of salt and sugar (1:1 ratio) is the Stockholm standard; some Swedes prefer 2:1 salt-to-sugar for a sharper cure.
Don't use ground white pepper — the warmth of freshly crushed whole peppercorns is essential and very different.
The mustard sauce keeps refrigerated for 5 days and is delicious on hot potatoes, in chicken salad, or with smoked mackerel.
Beetroot-cured gravlax — add 200 g grated raw beetroot to the cure for a magenta-edged ruby salmon, very Stockholm-modern.
Aquavit-spiked — sprinkle 2 tbsp aquavit over the salmon before applying the cure for warm caraway notes.
Citrus gravlax — add finely grated zest of 1 orange and 1 lemon to the cure for a brighter flavour.
Hot-smoked finish — after curing, cold-smoke the salmon over alder for 2 hours for a Norwegian-Swedish hybrid.
Cured gravlax keeps refrigerated, tightly wrapped, up to 7 days (flavour deepens daily). Freezes well 2 months — slice before freezing for easier portioning. Mustard sauce keeps 5 days refrigerated. Never refreeze the salmon once thawed and cured.
Gravlax originated with medieval Scandinavian fishermen who literally buried salt-cured salmon in sand above the tideline, where it fermented gently in cool earth and kept for months. The 'grav' in the name still means 'grave'. The modern refrigerator-cured, dill-perfumed version was perfected in 19th-century Swedish bourgeois kitchens and became a smörgåsbord essential.
Technically yes — it's not cooked with heat. But the salt cure denatures the proteins and inhibits bacteria, similar to cured ham. As long as the salmon is fresh or properly frozen, it's safe.
Tradition — white peppercorns have a sharper, hotter, more floral note that doesn't visually contrast with the pale flesh. Black would work but looks rustic, not classic.
Yes — if it has been previously frozen below -20°C for 24+ hours (most supermarket salmon has), it's safe for curing. Thaw slowly in the fridge before curing.
Whisk vigorously with 1 tsp very hot water added slowly to re-emulsify; or start a fresh batch and slowly whisk the broken sauce into it as you would a broken mayonnaise.
