{"schema":"askedwell-answer-v1","url":"https://askedwell.com/pages/what-ratio-of/gravlax-salt-sugar","question":"What ratio of salt to sugar for gravlax cure?","short_answer":"Classic gravlax: 1:1 ratio salt:sugar by weight. For 1 lb (454g) salmon: 60g salt + 60g sugar + 1 bunch fresh dill + 1 tbsp crushed white peppercorns. Cure 36-48 hours refrigerated, weighted, flipping every 12 hours.","long_answer":"**The canonical gravlax cure (Nordic tradition)**\n\nGravlax (gravad lax in Swedish, gravlaks in Norwegian) is salt-cured fresh salmon — a Scandinavian preserve traditionally buried in sand or earth (\"grav\" = grave/hole + \"lax\" = salmon), now refrigerated. Unlike smoked salmon (lox), gravlax has no smoke; the cure is purely salt + sugar + dill + sometimes other aromatics.\n\n**The 1:1 ratio (most published recipes)**\n\nFor each 1 lb (454g) of salmon fillet, skin-on:\n- 60g kosher salt (about 1/4 cup Diamond Crystal)\n- 60g granulated sugar (about 1/4 cup + 1 tsp)\n- 1 bunch fresh dill, roughly chopped (about 1 oz / 30g)\n- 1 tbsp crushed white peppercorns (or 1 tsp ground)\n- Optional: 1-2 tbsp vodka, gin, or aquavit\n- Optional: zest of 1 lemon\n\n**Variations on the ratio**\n\n- **Standard (1:1):** balanced flavor, slightly sweet, used by most published recipes\n- **Salt-heavier (1.5:1 salt:sugar):** more savory, drier texture, longer keeping; preferred by Norwegian tradition\n- **Sugar-heavier (1:1.5):** sweeter, slightly more delicate; used in some Swedish modern versions\n- **Heavy cure (2:1 or 3:1 salt-heavy):** for thicker fillets or longer keep (4+ days cure); produces firm-textured gravlax\n\n**Method**\n\n1. Trim salmon: remove pin bones with tweezers; leave skin on\n2. Mix dry cure: salt + sugar + crushed pepper in bowl\n3. Spread half the cure on a piece of plastic wrap large enough to wrap fillet\n4. Place salmon skin-down on cure; spread remaining cure evenly over flesh\n5. Pile dill on top (chopped roughly, including stems for flavor)\n6. Wrap tightly in plastic wrap (2 layers)\n7. Place in shallow dish; weight with heavy plate + 2-3 cans (puts pressure on cure to press liquid out + into fish)\n8. Refrigerate 36-48 hours, flipping every 12 hours so cure works both sides evenly\n9. After cure: unwrap, rinse briefly under cold water OR pat away cure with paper towels (some prefer not rinsing)\n10. Slice paper-thin on a bias, against the grain\n\n**Cure time by fillet thickness**\n\n- Thin (1/2 inch / 1.3 cm): 24-30 hours\n- Standard (1 inch / 2.5 cm): 36-48 hours (most home fillets)\n- Thick (1.5+ inch / 3.8 cm): 48-72 hours\n- Belly portion or whole side: 72-96 hours\n\nToo short = wet, fishy, under-cured (food safety risk).\nToo long = oversalted, dry, leathery.\n\n**Why salt + sugar at 1:1**\n\nSalt alone produces a harsh, dry cure (think country ham). Sugar tempers salt's pull while still allowing osmotic dehydration. The salt + sugar combination:\n- Draws water from the fish (firms texture)\n- Adds dissolved cure ions into the fish flesh (preserves)\n- Sugar feeds gentle browning + flavor compounds (Maillard at room temp = minimal but flavor compounds form)\n- Sugar balances the high salt percentage at the palate\n\n**Spice + aromatic role**\n\nDill is the canonical herb — its anise/pine notes complement salmon. Other additions:\n- Crushed peppercorns (white or pink) = warmth + classic\n- Lemon zest = brightness + cuts richness\n- Coriander seeds (crushed) = citrusy depth\n- Beets (Nordic variation) = stains pink, sweet earthy\n- Vodka/aquavit/gin = surface antimicrobial + flavor depth\n\nSkip if novelty: chili, garlic, exotic spices — they clash with the delicate cure.\n\n**Safety**\n\nFresh salmon used for gravlax should be sushi-grade or frozen at -4°F (-20°C) for 7+ days first (kills parasites per FDA guidance). Cured salmon is NOT cooked; you're relying on salt + cold + freezing-first for safety. Don't use thawed previously-frozen \"to be cooked\" salmon without first re-freezing for parasite kill.\n\n**Storage**\n\nCured gravlax (wrapped tightly) keeps 5-7 days in fridge after cure. For longer: slice, layer with parchment between slices, vacuum-seal — holds 2-3 weeks. Freezing acceptable but texture suffers slightly upon thaw.\n\n**Cross-reference:** see /pages/what-ratio-of/cure-salt-nitrite for nitrite-based cures (vs gravlax's nitrite-free) + /pages/how-long-does/gravlax-cure for timeline-focused view + /pages/what-ratio-of/salt-to-meat-dry-brine for general meat-salt ratio principles.","ranges":[{"condition":"1 lb (454g) standard fillet","duration":"36-48 hour cure","note":"60g salt + 60g sugar + dill + pepper"},{"condition":"2 lb (907g) fillet","duration":"36-48 hour cure","note":"120g salt + 120g sugar + dill + pepper"},{"condition":"Thin slices (under 1/2 inch)","duration":"24-30 hour cure","note":"Same 1:1 ratio; less time"},{"condition":"Whole side (4-5 lb)","duration":"72-96 hour cure","note":"300g salt + 300g sugar; flip every 24 hr"}],"variables":[{"name":"Salmon thickness","effect":"Thin: 24-30 hr.

FDA recommends salmon for raw consumption be frozen at -4°F (-20°C) for 7 days to kill parasites. Most commercial salmon labeled \"sushi-grade\" or \"previously frozen for raw use\" has been treated this way. Thaw in fridge before curing; the cure proceeds normally. Twice-frozen (frozen → thawed → cured → not eaten → frozen again) is fine for safety but texture degrades."},{"question":"My gravlax tastes too salty — what to adjust?","answer":"Three fixes: (1) Reduce salt-to-sugar to 1:1.2 ratio (slightly sugar-heavy). (2) Reduce cure time by 6-12 hours; check at 24 hours and slice a small bit to taste. (3) Rinse cure off more thoroughly + soak the cured fillet in cold water for 30 min before serving. The 1:1 ratio is widely-published as balanced but personal preferences vary; if you find 1:1 always salty, recalibrate to 1:1.5 sugar-heavy."},{"question":"Why is my gravlax dry instead of silky?","answer":"Likely over-cured. Gravlax should be firm but moist — sliceable, slightly translucent at the edges, with a glossy interior. Dry/leathery means either: (1) cure time too long (40+ hours on 1-inch fillet = dry). Reduce to 30-36 hours. (2) Salt percentage too high. Stick to 60g salt per 454g salmon (about 13%); higher = drier. (3) Skipped weighting. Without pressure, cure doesn't penetrate evenly + interior stays wet while surface dries."}],"keywords":["gravlax cure ratio","gravad lax recipe","salt sugar salmon cure","gravlax salt percentage","Nordic cured salmon"],"category":"cooking","date_published":"2026-05-21","date_modified":"2026-05-21","license":"CC-BY-4.0","attribution":"https://askedwell.com"}
