What is smoked salmon?
Smoked salmon is salmon that has been salt-cured and then exposed to the smoke of aromatic woods (oak, beech, cherry, or apple) for a specific period. The result is a product with a silky texture, delicate flavor, and a smoky aroma that can be subtle or intense depending on the method used. It is one of the world's most prized gourmet products and a staple of Nordic, British, Jewish, and increasingly, Mediterranean cuisine.
In Spain, the consumption of smoked salmon has multiplied in recent decades. It has gone from being an exclusive product in Christmas hampers to being present in the refrigerators of millions of households throughout the year. At Bacalalo, we offer premium smoked salmon from different origins and smoking methods, because we know that not all smoked salmon is the same — and the differences matter.
Smoked salmon is much more than an ingredient: it is a complete gastronomic product that can be enjoyed on its own, with no further preparation than serving it at the right temperature and with a fine slice. Understanding its varieties, preparation methods, and uses will allow you to appreciate and choose with discernment.
Cold smoking vs. hot smoking
The fundamental difference between the two smoking methods is temperature:
Cold smoking
The salmon is exposed to smoke at a temperature of 20-30 °C (68-86 °F) for 12-48 hours. At this temperature, the salmon does not cook: it remains raw but cured. The result is a product with a silky, translucent, and unctuous texture, sliced into thin, almost transparent slices. This is the classic smoked salmon found in gourmet stores, served on toast and bagels, and associated with brunch and celebrations.
- Texture: silky, unctuous, melts in the mouth
- Color: intense orange to pale pink, translucent
- Flavor: subtle, delicate smoky, buttery
- Use: on its own, in salads, on toast, uncooked
Hot smoking
The salmon is smoked at 60-80 °C (140-176 °F) for 4-8 hours. At this temperature, the salmon does cook. The result is a product with a firm, flaky texture (it crumbles into flakes), with a more intense and pronounced smoky flavor. It is less elegant than cold-smoked but tastier and more versatile in cooking.
- Texture: firm, flaky, crumbles into flakes
- Color: dark orange, opaque
- Flavor: intense smoky, drier
- Use: in pasta, warm salads, rillettes, sandwiches
Types of salmon: wild vs. farmed
Farmed Atlantic salmon (Salmo salar)
95% of the smoked salmon on the market comes from farmed Atlantic salmon, mainly from Norway, Scotland, and Ireland. It is a salmon with fatty flesh, a smooth texture, and a delicate flavor. The intramuscular fat (visible white streaks) is what gives it its silky texture when cold-smoked. The best farmed salmon comes from farms with cold, strong currents, where the fish get more exercise and develop more muscle and less fat.
Wild Pacific salmon
Wild salmon (sockeye, king/chinook, coho) has less fat, firmer flesh, and a more intense red color due to the natural astaxanthin in its krill and shrimp diet. When cold-smoked, it has a less silky texture but a more complex and intense flavor. It is more expensive and harder to find, but its quality is exceptional.
Which is better?
It depends on the use. For thin slices served on their own (brunch style), farmed Atlantic wins for its silky texture. For cooking (pasta, quiches, warm salads), wild works better because it holds up to heat without falling apart. In general, a good quality Scottish or Norwegian farmed Atlantic salmon is the most versatile and balanced option.

The smoking process step-by-step
- Selection and filleting: high-quality fresh salmon pieces are chosen. Bones are removed with tweezers.
- Salting/curing: the salmon is covered with a salt mixture (sometimes with sugar, dill, pepper) for 12-24 hours. The salt extracts moisture and firms the texture.
- Washing and drying: the salt is removed, the fillet is washed, and allowed to air dry for several hours until a sticky film (the "pellicle") forms on the surface, which is essential for the smoke to adhere.
- Smoking: the salmon is placed in a smoker with wood smoke. Cold (20-30 °C, 12-48h) or hot (60-80 °C, 4-8h).
- Resting: after smoking, the salmon rests for 24-48 hours in the cold so that the flavors stabilize.
- Slicing and packaging: it is sliced thin (by hand or machine) and vacuum-packed.
The wood used for smoking greatly influences the flavor. Oak gives a classic, balanced smoke. Beech is milder and sweeter. Cherry and apple add fruity notes. Whisky cask (used whisky barrels) is a premium trend that provides vanilla and malt notes.
How to choose good smoked salmon
- Origin: look for Scotland, Norway, Ireland, or Alaska. Avoid generic "EU/non-EU origin."
- Method: "cold-smoked with oak wood" is the classic quality reference.
- Color: uniform orange, no dark spots or excessive white parts (surface fat).
- Texture to the touch: it should be firm but flexible, not soft or rubbery.
- Ingredients: salmon, salt. Period. If the list includes colorings, preservatives, or smoke flavorings, it's an inferior product.
- Cut: hand-sliced pieces are thicker and more irregular but of higher quality. Machine-sliced pieces are thinner and more uniform.
- Price: quality smoked salmon is not cheap. Below €30/kg, be suspicious. A premium product will be between €45-80/kg.
Storage and shelf life
- Unopened (vacuum-packed): in the refrigerator (0-4 °C / 32-39 °F), until the indicated expiration date (usually 3-6 weeks from packaging).
- Once opened: consume within 2-3 days. Wrap in film or store in an airtight container. As the days pass, the salmon oxidizes and darkens.
- Freezing: yes, it can be frozen (up to 2-3 months). The texture changes slightly upon thawing, but it is perfectly acceptable. Always thaw in the refrigerator, never at room temperature.
- Serving temperature: remove from the refrigerator 15-20 minutes before serving. At room temperature (not cold), the aromas and texture are best appreciated.
A sign that the smoked salmon is past its prime: strong fishy odor (not smoky), slimy or soft texture to the touch, brown discoloration at the edges. If you detect any of these signs, do not consume it.
How to serve smoked salmon
On its own, uncooked (the classic way)
Slices of smoked salmon are arranged on a board or plate, slightly separated, and accompanied by:
- A few drops of lemon (never soak: acid "cooks" the salmon)
- Capers
- Finely sliced red onion rings
- Rye bread, blinis, or toast
- Sour cream or cream cheese
- Fresh dill
At brunch
Smoked salmon is the king of international brunch: on bagels with cream cheese, with Eggs Benedict (Eggs Royale), with pancakes, with avocado on toast, or simply with scrambled eggs. It's an ingredient that elevates any breakfast to a premium category.
In elaborate dishes
Pasta (tagliatelle with smoked salmon and cream), quiche, salads (spinach + smoked salmon + avocado), tartare, rillettes, mousse, sushi... Smoked salmon is extremely versatile. Discover more ideas in our guide to smoked salmon recipes.
How to slice smoked salmon
If you buy a whole piece (unsliced), the cut is essential:
- Knife: use a long, flexible, very sharp knife (like a salmon or carving knife).
- Angle: slice diagonally, at a 30-45° angle to the board. This yields wide, thin slices.
- Direction: always from the tail towards the head, following the grain.
- Thickness: as thin as possible, almost transparent. The slices should be translucent when held up to the light.
- The skin: the knife glides between the flesh and the skin, leaving the skin attached to the board.
Slicing smoked salmon by hand is an art that requires practice. In gourmet stores and at Bacalalo, salmon is hand-sliced in front of the customer, ensuring freshness and optimal thickness. An expert slicer can produce slices 1-2 mm thick that will melt in your mouth.

Its main limitation is its sodium content (from the curing salt), which makes it unsuitable for strict salt-free diets. For more details, consult our guide on the properties of smoked salmon.
