Salmon Salmo salar / Oncorhynchus spp.
Skin-side down for most of the cook. Flip it for the last thirty seconds, not before.

In the kitchen
Under heat
The fat between the muscle segments melts and bastes the flesh from inside, which is why fattier cuts stay moist even slightly overcooked.
Against air
Exposed flesh oxidizes fast — the gray layer that develops on a fillet's surface is fat breaking down, and it won't taste as good even before it's gone bad.
In storage
Use within a day or two of buying, wrapped tight against air — the fat in fish turns faster than in most meat.
At the shop
Bright color and a clean ocean smell, not a fishy one. Press it — it should spring back, not leave a dent.
Which variety, for what
- Farmed Atlantic
- Consistently fattier, which makes it more forgiving to cook and less likely to dry out.
- Wild (sockeye, king, coho)
- Leaner and firmer — cooks faster and needs closer attention to avoid overcooking.
Beyond the kitchen
THE COLOUR IS FEED
Wild salmon are pink from astaxanthin in the crustaceans they eat. Farmed salmon flesh would be pale grey without it, so the pigment is added to feed, and farmers select a target shade from a standardised colour fan. It is the same compound either way.
THEY RETURN TO THEIR OWN RIVER
Salmon navigate thousands of miles of open ocean and then locate the stream they hatched in, apparently using magnetic orientation at sea and scent memory close in. Homing accuracy is high enough that river populations remain genetically distinct.
A KEYSTONE SPECIES
Spawning salmon carry marine nitrogen far inland, and bears and eagles distribute their carcasses into forests. Isotope studies find ocean-derived nitrogen in streamside trees, meaning Pacific forests are measurably fed by fish.
NORWAY REINVENTED SUSHI
Salmon was not traditionally used in Japanese sushi because Pacific salmon carries parasites. A Norwegian government trade campaign through the 1980s and 90s, Project Japan, deliberately introduced farmed Atlantic salmon for raw consumption — and salmon nigiri, now ubiquitous, is the result.
A longer history
Salmon have been central to human settlement wherever they run. Pacific Northwest peoples built complex societies substantially on the salmon runs, with elaborate fishing technology, preservation by smoking and drying, and ceremonial practice recognising the fish's return. In northern Europe, salmon rivers were valuable enough to be regulated by medieval law.
Wild Atlantic salmon collapsed across much of its European range through the nineteenth and twentieth centuries under dams, pollution and overfishing, and the species is now absent or heavily reduced in many rivers where it was once so abundant that apprentices' indentures are said to have limited how often they could be fed it — a story repeated often and documented rarely.
Commercial salmon farming began in Norway in the 1960s and 70s and expanded enormously, making a former luxury into an everyday supermarket fish. It also created a permanent set of arguments — sea lice, escapes, feed inputs, effects on wild stocks — that remain genuinely contested rather than settled.
IF YOU ARE EATING IT RAW
Fish served raw or lightly cured should be frozen first to a temperature and duration that food safety authorities specify for parasite control, or bought from a supplier who has already done it. Requirements differ between jurisdictions — check your own food safety agency's guidance, and buy from a fishmonger you can ask directly.
