Cold Smoked Salmon

Cold smoked salmon feels like a luxury, but it is well within reach of a home curer. A good side of salmon, a measured cure and a gentle, cold smoke are all it takes, and the result is far better than most of what you can buy.

Introduction

I cure it as an equilibrium cure, which means the salt and sugar are weighed against the fish rather than piled on and rinsed off. That gives a clean, even result every time. Because the fish is never cooked, only cured and smoked, the pink salt is there to keep it safe through the long, low smoke. Freeze the salmon first, keep everything cold, and take your time over the pellicle and the smoke.

Purpose and scope

The recipes published on The Curesmith are intended for educational and informational purposes only. Meat curing, fermentation and smoking involve processes that, if carried out incorrectly, can result in products that are unsafe to eat. By using any recipe on this website you acknowledge that you do so entirely at your own risk, and you agree that The Curesmith and its authors cannot be held liable for any outcome arising from its use.

Limitation of liability

The Curesmith and its authors accept no responsibility or liability for any illness, injury, loss or damage arising from the use of these recipes, including but not limited to illness caused by improperly cured, handled or cooked meat products, errors in measurement or technique, equipment failure, or deviation from the stated method or quantities.

Nitrite and cure safety

Meat curing involves the use of nitrite salts, which must be measured accurately and used strictly according to the quantities specified. Nitrite in excessive quantities is toxic. Please ensure you understand the following before proceeding:

  • Always use a calibrated digital scale accurate to at least one gram. For smaller batches, a scale accurate to 0.1g is strongly recommended.
  • Never exceed the stated cure amounts. Never substitute cure types without recalculating.
  • Store all curing salts clearly labelled, separately from regular salt, and out of reach of children.
  • Different cure products have different nitrite concentrations. Always check your manufacturer's label and adjust quantities accordingly.

Food hygiene and cross-contamination

Raw and cured meat products must be stored, handled and prepared in a clean environment using food-safe equipment. Hands, surfaces, tools and containers must be thoroughly cleaned and where appropriate sanitised before use. Cross-contamination between raw meat and ready-to-eat products must be avoided at all times.

Temperature control

Temperature control is critical throughout all curing and smoking processes. Inadequate temperature management can allow the growth of dangerous pathogens including Clostridium botulinum, Listeria monocytogenes, Salmonella and E. coli. A reliable refrigerator thermometer and a calibrated probe thermometer are essential pieces of equipment for anyone producing cured or smoked meat at home.

Uncooked cured products

Whole muscle products that are eaten without cooking, such as air-dried bresaola, coppa or prosciutto, must reach their target weight loss before consumption. Products that have not been cured and dried to the correct specification may not be safe to eat uncooked. Pancetta and guanciale cured to less than 38% weight loss must not be consumed uncooked.

Bacon and other uncooked cured products

Bacon and other uncooked cured products must be cooked thoroughly before eating. Cold smoking adds flavour and colour but does not cook the product. A cold-smoked bacon or sausage remains a raw product and must reach a safe internal temperature before it is safe to consume. For pork and beef this is 72°C / 162°F. For poultry this is 74°C / 165°F.

When in doubt, seek professional guidance

If you are unsure about any aspect of the curing, smoking or fermentation process, we strongly encourage you to seek formal training or guidance from a qualified food safety professional before proceeding. The information on this website is not a substitute for proper food safety education and training.

Commercial production

These recipes are produced for home and small-scale producers. They are not intended for commercial food production. Commercial meat processing is subject to regulatory requirements that vary by country and jurisdiction. If you intend to produce cured or smoked products for sale, you must ensure full compliance with all applicable food safety regulations in your region.

Method

1
Mix the cure. Weigh and combine the salt, sugar, pink salt and the ground spices into an even mix. Because this is an equilibrium cure, weigh accurately: every gram goes into the fish. The pink salt is Cure #1 and is essential for safe cold smoking.
2
Cure in a bag (EQ). Rub the cure over all surfaces of the fillet, sprinkle over the vodka, and seal it in a vacuum or zip bag, or lay it in a snug non-reactive dish. No heavy weighting is needed. An EQ cure holds every gram you weighed, so it cannot over-salt.
3
Cure, turning once. Refrigerate at 2 to 4 C (36 to 39 F) for the cure time the thickness estimate above gives, turning the bag once so the cure works evenly. It is ready when the thickest part feels firm and dense. Leaving it a little longer is safe, since the cure is already at equilibrium.
4
Form a pellicle. Lift the fillet out and pat it dry (a very quick cold rinse to lift loose surface spice is fine, then pat dry). Rack it uncovered in the fridge for 4 to 24 hours, until the surface is dry and slightly tacky. Smoke will not take on a wet surface.
5
Cold smoke below 25 C. Cold smoke for about 6 hours, or to taste. Keep the smoker and the fish below 25 C (77 F) at all times, never let either rise above it. Alder, oak or a fruitwood all suit salmon.
6
Rest, then slice. Wrap the smoked side in parchment or butcher's paper and refrigerate overnight to settle. Slice thin, on a shallow angle, from the tail towards the head.
Key tipsThis is an equilibrium (EQ) cure: the salt, sugar and pink salt are measured as a percentage of the fish and all of it is absorbed, so it cannot over-salt and needs no rinsing off. Weigh accurately, keep everything cold, form a proper pellicle before smoking, and hold the smoke below 25 C (77 F) throughout.
ImportantCold-smoked salmon is cured and smoked but not cooked; it is eaten as is. Because of that, the pink salt (Cure #1) is not optional, and the fish must be frozen solid first for parasite control, made from the freshest salmon you can source, and kept cold throughout. Keep it refrigerated and use within about 3 weeks; change the wrapping if it becomes damp.
