Beetroot Gravlax

Two-day beetroot-and-dill cure that turns salmon a vivid magenta

Origin: Scandinavia

From the journey of Beetroot.

Gravlax (literally 'buried salmon' in Swedish) is the ancient Scandinavian technique of salt-curing raw salmon, originally done by burying it in the ground to slow-ferment. The modern gravlax tradition omits the burial but retains the salt-sugar-herb cure, producing a silky, tender, deeply flavoured salmon that is eaten in thin slices across the Nordic world from Christmas to midsummer. The beetroot variant is a modern refinement of the classic dill cure: grated raw beetroot is packed around the salmon alongside the salt, sugar, and dill, and over the two days of curing the vivid betacyanin pigment migrates into the flesh, turning the exterior of the fish a brilliant, saturated magenta while the interior remains the natural deep orange of the salmon. The effect is both visually spectacular and delicately flavoured: the beet adds an earthy sweetness to the outer layer of the fish without overpowering the salmon. Beetroot gravlax became fashionable in British and European restaurants in the 2000s and is now a standard of Nordic-influenced cooking worldwide.

Ingredients

Fish

  • 800 g salmon fillet, skin on, pin-boned (centre-cut is best)

Cure

  • 300 g raw beetroot (about 2 medium), peeled and coarsely grated
  • 50 g coarse sea salt
  • 50 g caster sugar
  • 30 g fresh dill, roughly chopped (stalks and all)
  • 1 tbsp vodka or aquavit (optional)
  • 1 tsp coarsely cracked black pepper

Serving

  • 150 ml soured cream, to serve
  • 2 tbsp Swedish-style mustard (or wholegrain mustard with a little sugar), to serve
  • 1 tbsp finely chopped fresh dill, to serve
  • rye crispbread or dark rye bread, to serve

Method

  1. Lay a large sheet of cling film on a work surface, then place a second sheet on top. Mix together the salt, sugar, dill, cracked pepper, and vodka (if using) in a bowl, then stir in the grated beetroot.
  2. Spread half the beetroot cure in a thick layer in the centre of the cling film, roughly the size of the salmon fillet. Place the salmon on top, skin-side down.
  3. Spread the remaining cure over the flesh side and top of the salmon, pressing it on firmly. Wrap the cling film tightly around the whole parcel, folding the ends under to create a sealed package.
  4. Place the wrapped salmon in a shallow dish or tray. Place a flat board or second tray on top and weigh it down with tins or a heavy pan. Refrigerate for 48 hours, turning the parcel over every 12 hours.
  5. After 48 hours, unwrap the salmon. The exterior will be a vivid magenta. Scrape off and discard the cure mixture. Pat the salmon dry with kitchen paper.
  6. Using a long, thin knife, slice the salmon thinly on the diagonal, cutting away from the skin. Mix the soured cream, mustard, and fresh dill for the sauce.
  7. Arrange the magenta-tinged slices on a board or plates. Serve with the mustard cream, rye crispbread, and a wedge of lemon.

Notes

Cured salmon keeps refrigerated, well wrapped, for up to 5 days. The colour is most vivid on the exterior slices; as you cut deeper into the fillet the salmon returns to its natural orange. This contrast (magenta outside, deep orange within) is part of the aesthetic pleasure of the dish.

🌍Origin

— c. 2000 BCE

🌱Domestication

Beetroot belongs to the species Beta vulgaris, whose wild ancestor Beta vulgaris subsp. maritima (sea beet) grows along the coastlines of the Mediterranean and Atlantic Europe. The earliest evidence of human use comes from the eastern Mediterranean: Egyptian sources from around 2000 BCE record the leaves being eaten as a vegetable, while the root at this stage remained thin and fibrous, more a weed than a crop. The Babylonians grew beet in their hanging gardens, and a cuneiform tablet from Nippur (c. 800 BCE) describes beet leaves as tribute produce. The ancient Greeks cultivated beet primarily for its leaves, offering the roots to Apollo at Delphi and recording their medicinal properties. Roman agronomists Columella and Apicius both document beet cultivation: Columella describes both white and dark varieties grown for the root as well as the leaf, while Apicius includes recipes for boiled beet with cumin, oil, and vinegar, an essentially unchanged preparation still found across the Mediterranean. The transition from leaf crop to root vegetable is a gradual story of selective cultivation. Roman-era beets were still long and parsnip-shaped. The round, deeply pigmented root we recognise today, the result of centuries of selection for a swollen, sugar-rich taproot, does not clearly appear in the record until 16th-century Germany, where the first illustrations of a recognisably bulbous red root appear in Leonhart Fuchs's De Historia Stirpium (1542). By that point, three distinct cultivated forms had diverged from the original sea beet: the garden beet (eaten as a vegetable), the sugar beet (bred for maximum sucrose content in the 18th century), and the mangel-wurzel (grown as livestock fodder). All are the same species; their separation is entirely one of human selection.

Global Voyage

Beetroot's spread from its Mediterranean heartland follows the standard routes of European expansion. Roman legions carried Beta vulgaris across northern Europe, where beet cultivation took hold in Germany and the Low Countries during the early medieval period. By the 11th century, beet appeared in monastic herb gardens from Britain to Poland. The root's tolerance for cold soils made it a natural fit for the agriculture of Eastern Europe, and it was in the Slavic lands (Poland, Ukraine, Russia, and the Baltic states) that the garden beet found its greatest culinary expression. The Polish word burak and the Russian svyokla both appear in medieval sources, and by the 16th century, beet-based soups were a staple of the Polish and Ukrainian diet. Jewish communities in the Ashkenazi diaspora adopted beet enthusiastically, it provided sweetness, colour, and preservation through fermentation (beet kvass, a lacto-fermented beet drink, predates the modern pickle jar by centuries). The Dutch and British introduced pickled beetroot to their colonial territories in the 18th and 19th centuries, carrying it to South Africa, Australia, and New Zealand, places where canned and pickled beetroot became embedded in local food culture in a way that has never quite left. The 18th century also saw the emergence of sugar beet as an industrial crop: following Napoleon's continental blockade of British cane sugar, European chemists and agronomists developed high-sucrose beet varieties that by the 1830s supplied a significant portion of European sugar. This agricultural revolution had no culinary expression (sugar beet is purely a factory crop) but it reshaped global trade in profound ways.

🍽Modern Culinary Role

Beetroot is grown across every temperate continent and occupies a unique position in the global kitchen as both an ancient preservation ingredient and a modern health food. Its deep crimson pigment (betacyanin) is used as a natural food colourant and has driven a substantial health-food market since the early 2000s. Eastern European cuisines remain the cultural heartland: Ukraine, Poland, Russia, Lithuania, and Romania all centre the root in their national soups. Scandinavia uses it in cured fish preparations and as a vivid salad component. The British, despite a post-war history of consuming it only from the vinegar jar, have seen a revival of fresh beetroot cooking driven by restaurant culture. In Australia, the canned beetroot slice on a burger is one of the most distinctly national food identifiers on earth. Georgia has a sophisticated walnut-beetroot tradition (pkhali). South Africa, India, and the Middle East each have distinct beetroot preparations. Three major varieties dominate today's kitchen: the deep crimson Detroit cultivar (the standard supermarket beet), the Chioggia or candy-stripe beet from the Veneto (white and red concentric rings, milder, eaten raw), and the golden or yellow beet (a paler, sweeter cultivar used across continental Europe). All three are Beta vulgaris; their differences are entirely cultivar-level.
