Eating in Iceland: Lamb, Skyr and Bread Baked Underground
Icelandic cooking makes far more sense once you stop looking for a Mediterranean-style abundance of ingredients and start reading it as a set of solutions. This is an island near the Arctic Circle with thin soils, a short growing season, no forests to speak of and, for most of its history, no way to import anything reliably. Nearly everything distinctive on an Icelandic table — the dried fish, the fermented shark, the cultured dairy, the autumn lamb — exists because it was a way of making food last through a winter, and the country's geothermal heat has since been turned to the same practical account.

A cuisine built on keeping things, not growing them
Iceland's traditional larder was assembled under real constraint. Grain barely grew, vegetables were limited to what would tolerate a cold, short season, and the settlers had cleared the birch woodland within a few generations, which removed both fuel for cooking and shelter for crops. What the country did have was fish, sheep, seabirds and dairy — and the problem was never catching or raising them but keeping them edible from autumn through to spring.
The techniques that answer that problem are the actual foundation of the cuisine: drying in the wind, salting, smoking with dried sheep dung where there was no wood to burn, fermenting, and preserving in whey. Harðfiskur, fish wind-dried until it tears into fibrous strips, is the clearest surviving example and is still eaten daily as a snack, usually with butter — a high-protein, essentially imperishable food that predates refrigeration by a thousand years and has simply never stopped being good. Reading the menu this way turns what can look like eccentricity into a coherent and rather impressive body of practical knowledge.
Bread baked in the ground, tomatoes grown in steam
The same geothermal heat that warms Icelandic houses and fills its swimming pools also cooks Icelandic food, and the most literal example is rúgbrauð, a dark, dense, faintly sweet rye bread. The dough is sealed in a container, buried in hot ground near a geothermal field, and left for around a day, cooking slowly at a steady low temperature with no oven and no fuel involved. Bread made this way is sometimes called hot-spring bread, and it is genuinely different from an oven-baked loaf — moister, denser and sweeter, because the long gentle heat converts more of the starch to sugar. Eaten with butter and smoked lamb or pickled herring, it is one of the most distinctive things you can eat in the country.
The less obvious application is greenhouses. Iceland heats and lights glasshouses with geothermal energy and domestic electricity, which is why a subarctic island produces its own tomatoes, cucumbers, peppers and salad leaves year-round, and why the produce section of an Icelandic supermarket is far better stocked than the latitude would suggest. Some growers have taken the principle to its logical extreme and cultivate bananas under glass. It is the same infrastructure story as the swimming pools, applied to lunch.
Lamb, and why Icelanders make a claim about it
Icelandic lamb is the country's proudest ingredient, and the claim made for it rests on how the animals live rather than on breed marketing. Sheep are turned out in spring and spend the summer roaming highland and mountain pasture largely unmanaged, grazing on wild grasses, moss campion, thyme and berries across enormous areas, before being gathered in the autumn in the réttir, the communal round-up that remains a genuine rural social event. The meat that results is lean and noticeably herbal, and because the sheep are slaughtered after a summer of that grazing, the seasonality is real rather than decorative.
The same animal shows up across the whole menu in ways that reflect the preservation habit: hangikjöt is lamb smoked and served cold in thin slices, a Christmas fixture; kjötsúpa is the plain, restorative lamb-and-root-vegetable soup that is arguably the true Icelandic comfort food and is served everywhere from farm kitchens to petrol stations. If you eat one traditional dish in the country, the soup is the least intimidating and among the best.
Skyr is not yogurt
Skyr looks like thick yogurt and is sold alongside it internationally, but technically it is a fresh cheese: milk is cultured, then the whey is strained off, which concentrates the protein and produces the characteristic density. It is made from skimmed milk, so it is naturally very low in fat while being high in protein, and Icelanders have been making it since the settlement era — it is one of the few genuinely continuous food traditions in the country, and for centuries the strained-off whey was itself used as a preservative for meat rather than discarded.
The everyday version is eaten plain or with berries and a little cream or milk stirred through to loosen it, and the flavour is markedly tarter than the sweetened export product suggests. Icelandic supermarkets carry a wall of it. It is also the cheapest genuinely good thing to eat in an expensive country, which makes it a practical staple for visitors as well as a cultural one.
The hot dog is the honest national dish
The pylsa occupies a place in Icelandic life that no amount of fine dining has displaced, and the reason it tastes different from hot dogs elsewhere is that it is made substantially from lamb alongside pork and beef. It is sold from stands, petrol stations and supermarket counters everywhere in the country, and it is one of the few things in Iceland that is unambiguously cheap.
Ordering it correctly is straightforward: ask for one with everything, and it arrives with both raw and crispy fried onions, ketchup, a sweet brown mustard and a mayonnaise-based remoulade. The combination of the two onion textures is the part people remember. Treating this as a lesser or novelty meal misreads the culture — it is what Icelanders actually eat, often after a swim, and the queue at a good stand is as likely to be locals on a lunch break as anyone else.
Þorramatur, hákarl and eating the difficult things
Iceland's most notorious foods are concentrated in Þorramatur, the spread of traditional preserved dishes eaten at midwinter gatherings called Þorrablót. It assembles exactly the larder described above — cured and smoked lamb, singed sheep's head, dried fish, rye bread, blood and liver sausage preserved in whey — and it is best understood as a deliberate seasonal revival of how people actually ate, somewhere between a harvest supper and a heritage event, rather than as everyday food.
Hákarl, fermented Greenland shark, is the item that travels furthest in reputation, and it has a genuine reason to exist. The flesh of that shark is toxic when fresh because of the compounds the animal uses to survive at depth and in cold; burying and pressing it for weeks and then hanging it to dry for months breaks those compounds down and renders it safe to eat. It was, in other words, a way of turning an inedible but abundant animal into winter food, and it is served in small cubes, usually with a spirit alongside. Whether you enjoy it is beside the point of why it exists — and no Icelander will be offended if you try one cube and stop.
