{"schema":"askedwell-earned-page-v1","url":"https://askedwell.com/pages/how-long-does/gravlax-cure","question":"How long does gravlax take to cure?","short_answer":"Gravlax cures 36–72 hours refrigerated under weight, depending on thickness. Standard 1-inch salmon fillet: 48 hours. Thicker pieces: 60–72 hours. Salt + sugar + dill is the classic cure mix.","long_answer":"Gravlax is Scandinavian cured salmon — salmon fillet rubbed with a salt + sugar + dill mixture, weighted, and refrigerated for 1.5–3 days. The cure draws out moisture, firms the texture, and concentrates flavor. No cooking, no smoking — just salt-cure.\n\n**Standard timing (per fillet thickness):**\n\n**1-inch (2.5cm) thick salmon fillet:**\n- 36 hours: lightly cured, mild\n- **48 hours: standard target — firm, salty-sweet, beautifully translucent**\n- 60 hours: deeper cure, drier\n- 72 hours: fully cured + drier still\n\n**1.5-inch (4cm) thick fillet:**\n- 48 hours: under-cured center\n- **60 hours: standard target**\n- 72 hours: fully cured\n\n**Thin pieces (1/2-inch / 1.5cm):**\n- 24 hours: cured enough\n- 36 hours: standard target\n\n**The cure mixture (per 1 kg salmon):**\n- 60g coarse kosher salt (~5–6% by weight)\n- 60g sugar (white, or 50/50 white+brown)\n- 1 small bunch fresh dill, chopped (essential to gravlax identity)\n- Optional: white pepper, fennel seed, juniper, vodka (Aquavit traditional), beetroot\n- Optional: lemon zest, capers\n\n**The method (Scandinavian standard):**\n1. Mix salt + sugar + dill thoroughly\n2. Spread cure mix on both sides of salmon fillet\n3. Place skin-down in non-reactive dish (glass, ceramic, plastic)\n4. Top with another fillet skin-up (sandwich, classic) OR weight directly\n5. Cover with plastic wrap pressed onto surface\n6. Weight with 2–3 lbs (cans, bricks, or weighted plate)\n7. **Refrigerate 36–72 hours, flipping every 12 hours**\n8. After cure: rinse off cure, pat dry\n9. Slice paper-thin against the grain on a slight angle\n\n**Why weight + flipping matter:**\n- Weight presses cure into flesh evenly\n- Flipping ensures even cure on both sides\n- Without weight: top dries faster than bottom (uneven cure)\n- Without flipping: side touching weight cures more than opposite\n\n**The \"done\" indicators:**\n- Color: deep orange-pink, slightly translucent (raw was bright opaque)\n- Texture: firm to touch (not soft anymore)\n- Center: same color/texture as edges (cured all the way through)\n- Smell: clean ocean + dill, no fishy-raw smell\n\n**Don't:**\n- Skip the weight (uneven cure)\n- Use farmed salmon flesh-side down on the dish (sticks; place skin-down)\n- Add sugar in 1:2 salt:sugar ratio (too much salt = harsh; 1:1 is sweet spot)\n- Skip flipping (one side over-cures)\n- Use frozen-then-thawed salmon for sashimi-style serving (fish must be flash-frozen first for parasites)\n\n**Storage of finished gravlax:**\n- Refrigerated (wrapped in plastic): 1 week\n- Vacuum-sealed: 2 weeks\n- Frozen: 3 months\n- Texture continues firming for first 24 hours after rinse; peak flavor at days 3–5 post-rinse\n\n**Variations:**\n- **Beetroot gravlax**: rubbed with grated raw beet → vibrant pink color, earthy flavor\n- **Vodka gravlax**: brushed with Aquavit/vodka before cure → traditional Nordic version\n- **Smoked gravlax**: gravlax + cold smoke 4–6 hours after cure\n- **Lime gravlax**: replaces dill with lime + cilantro for fusion variation\n\n**Safety note (parasites):**\n- Wild Atlantic salmon: traditional gravlax country origin; parasites rare but possible\n- Farmed salmon: parasite-controlled; safer for traditional gravlax\n- For sushi-grade safety: USE FISH PREVIOUSLY FROZEN at -4°F (-20°C) for at least 7 days, OR frozen at -31°F (-35°C) for at least 15 hours\n\n**Cross-reference:** see /pages/how-long-does/preserved-lemon-cure for similar dry-cure methodology + /pages/how-long-does/curing-bacon for similar timing-by-thickness pattern.\n\nMost published references (Magnus Nilsson \"The Nordic Cookbook\", Michael Ruhlman + Brian Polcyn \"Charcuterie\", Hugh Fearnley-Whittingstall \"The River Cottage Fish Book\") converge on 48-hour cure for standard 1-inch fillets.","duration_iso":"P2D","ranges":[{"condition":"1-inch fillet, standard cure","duration":"48 hours (2 days)"},{"condition":"1.5-inch thick fillet","duration":"60 hours (2.5 days)"},{"condition":"Thin (1/2-inch) fillet","duration":"24–36 hours"},{"condition":"Quick light cure","duration":"24 hours"},{"condition":"Long-aged dry cure","duration":"5–7 days (very firm jerky-like)"}],"variables":[{"name":"Fillet thickness","effect":"Cure penetrates ~1cm per 12 hours from each surface"},{"name":"Salt-to-sugar ratio","effect":"1:1 standard; more salt = drier, sharper; more sugar = sweeter, milder"},{"name":"Temperature","effect":"38°F refrigerator is standard; warmer accelerates but risks unsafe bacterial growth"},{"name":"Weight pressure","effect":"Heavier weight (3+ lbs) = firmer denser cure; less weight = softer texture"}],"sources":[{"label":"Magnus Nilsson, \"The Nordic Cookbook\"","note":"Comprehensive Scandinavian cured-fish reference including traditional gravlax"},{"label":"Michael Ruhlman + Brian Polcyn, \"Charcuterie\"","note":"Detailed home-curing methodology including gravlax + variations"},{"label":"Hugh Fearnley-Whittingstall, \"The River Cottage Fish Book\"","note":"UK home reference for cured fish including gravlax timing"},{"label":"NCHFP cured fish guidelines","url":"https://nchfp.uga.edu/how/cure_smoke.html","note":"Food safety standards for cured fish + parasite control"}],"faq":[{"question":"Can I use frozen-then-thawed salmon for gravlax?","answer":"Yes, and it's actually recommended for safety — flash-freezing at -4°F for 7+ days kills parasites. Wild salmon especially should be frozen first. Farmed salmon has lower parasite risk but freezing is still standard practice for raw-served preparations."},{"question":"Why is my gravlax too salty?","answer":"Either: (1) cured too long (past 72 hours for thick fillets); (2) cure mixture had too much salt vs sugar (should be 1:1); (3) didn't rinse cure off thoroughly before serving. Soak in cold water 20 min if too salty to mellow."},{"question":"How thin should I slice gravlax?","answer":"As thin as possible — paper-thin slices, on a slight angle against the grain. Sharp slicing knife or even a sharp chef's knife works. Thinner slices = better flavor + texture experience. Hold the knife at 30° angle to the cutting board, slice with long single strokes."}],"keywords":["gravlax","salmon cure","scandinavian salmon","how long to cure gravlax","salt cured salmon","nordic cooking"],"category":"cooking","date_published":"2026-05-20","date_modified":"2026-05-20","license":"CC-BY-4.0","attribution":"https://askedwell.com"}
