Icelandic Cod: Why It's the Best in the World

Iceland: A country built on cod

Iceland is a volcanic island in the middle of the North Atlantic, with a population of barely 380,000 inhabitants and an economy that for centuries depended almost exclusively on one thing: cod. Until the 1990s, when tourism and technology began to diversify the economy, cod fishing accounted for more than 70% of Icelandic exports.

Iceland's relationship with cod is so profound that it led to three military conflicts with the United Kingdom, known as the "Cod Wars" (1958, 1972, and 1975), in which Iceland unilaterally expanded its territorial waters to protect its fishing grounds. A country of 200,000 inhabitants confronting a world power over a fish. And it won all three times.

This level of importance explains something fundamental: no country in the world manages its cod fishery with more rigor than Iceland. The catch quota is established with scientific data updated annually, traceability is complete (every vessel, every catch, every batch is registered), and investment in processing technology is cutting-edge. Icelandic cod is not only good because of its waters: it is good because the entire system around it is designed to produce the best possible product.

Colder waters, better cod

The quality of cod depends directly on the water temperature where the fish lives. And here Iceland has an insurmountable geographical advantage.

Cod (Gadus morhua) is a cold-water fish that thrives best between 2 °C and 8 °C. At these temperatures, its metabolism is slow, meaning it grows slowly but develops denser flesh, with more protein and less water. It's the same principle as with mountain animals that grow slowly and yield tastier meat.

Iceland's waters are in the perfect range: between 1 °C and 6 °C year-round. Furthermore, the confluence of the warm Gulf Stream (coming from the Caribbean) with the cold Arctic currents creates an area of extraordinary biological richness. Plankton thrives, small fish multiply, and cod feed abundantly. Well-fed cod in cold waters means firm, white, and gelatinous flesh.

Compare this to other fishing areas:

• Norway (Lofoten): waters between 4 °C and 10 °C. Slightly warmer, which produces slightly softer cod.
• Faroe Islands: waters similar to Iceland (3-7 °C). Comparable quality cod but with lower production.
• Barents Sea (Russia/Norway): very cold waters (0-4 °C) but with less biodiversity. Firm cod but less gelatinous.
• Canada (Newfoundland): waters between 0 °C and 5 °C. Historically the largest fishing ground in the world, but overfishing caused the population to collapse in 1992 and it has never fully recovered.

Icelandic Gadus morhua: distinguishing characteristics

The Icelandic Gadus morhua has physical characteristics that distinguish it from other origins:

• Whiter flesh: The diet rich in small fish and crustaceans gives Icelandic cod a bright ivory-colored flesh, without yellowish or grayish tones that indicate lower quality.
• More gelatin: The skins of Icelandic cod are thicker and more gelatinous. This is immediately noticeable when making a pil pil: the emulsion forms faster and the result is creamier.
• Flaky texture: When confiting or poaching an Icelandic loin, the flesh separates into large, regular flakes, separated by thin layers of gelatin. This is the texture that identifies premium cod.
• Higher protein content: Between 18% and 20% protein (vs 15-17% from warmer origins). More protein means more flavor and more body in the dish.
• Lower fat content: Icelandic cod is exceptionally lean (0.5-0.7% fat), but the small amount of fat it does have is concentrated in the liver, where the famous cod liver oil is produced.

Sustainable fishing: the Icelandic model

Sustainability is not a slogan in Iceland: it is survival. A country that depends on cod for its existence cannot afford the luxury of depleting its resources.

The Icelandic system works like this:

1. Annual scientific assessment: The Marine and Freshwater Research Institute of Iceland (Hafrannsóknastofnun) annually assesses the cod population through sampling campaigns using scientific trawls and acoustic data.
2. Total Allowable Catch (TAC): Based on scientific data, a maximum limit of tons that can be caught is established. The quota has varied between 150,000 and 250,000 tons annually in recent decades.
3. Individual Transferable Quotas (ITQ): The total quota is distributed among fishing vessels as individual rights. Each vessel knows exactly how much it can catch. Quotas can be bought or sold, creating a market that incentivizes efficiency.
4. Full traceability: Every catch is recorded with GPS, date, time, vessel, method, and volume. From the vessel to the store, every piece of Icelandic cod has a traceable history.
5. Control and sanctions: The Icelandic Coast Guard constantly patrols, and penalties for exceeding quotas are severe: multi-million fines and loss of license.

The result is that the Icelandic cod population is one of the healthiest in the North Atlantic. While Newfoundland (Canada) cod collapsed in 1992 and the North Sea remains under pressure, Iceland has maintained a stable and productive fishery for decades. When you buy Icelandic cod, you are buying a product that will exist for future generations.

Icelandic vs. Norwegian cod: real differences

It's the question we get asked most often at Mercat del Ninot: "Is Icelandic or Norwegian better?". The honest answer is that both are excellent, but they have different profiles.

Icelandic Cod

• Firmer and more compact flesh
• More gelatin in skin and bones
• Whiter color
• Larger flakes
• Best for: pil pil, confit, dishes where texture is key
• Price: slightly higher

Norwegian Cod (Skrei/Lofoten)

• Slightly tenderer and juicier flesh
• Abundant gelatin but slightly less than Icelandic
• White color with slightly creamier tones
• Slightly sweeter flavor
• Best for: stews, brandade, dishes where it's flaked
• Price: similar or slightly lower
• Skrei (wild migratory Norwegian cod) is the premium version from Norway, only available from January to April

In the detailed analysis of Norwegian cod you will find more information about the Norwegian origin. But our professional recommendation, after decades of working with both origins, is clear: for most preparations, Icelandic cod offers the best balance between texture, flavor and consistency.

Other origins: Faroe, Russia, Canada

In addition to Iceland and Norway, other origins compete in the Spanish market:

Faroe Islands

Danish archipelago between Iceland and Norway. Cold and rich waters, rigorous fisheries management. Faroese cod is of comparable quality to Icelandic cod, with excellent gelatin and firm flesh. Production is much smaller, making it harder to find but equally recommendable.

Russia (Barents Sea)

Enormous production volume (it is the largest cod fishery in the world). Variable quality: the best Russian pieces are excellent, but traceability and quality controls are less rigorous than in Scandinavia. Russian cod is usually cheaper and is mainly used for industrial salting and drying.

Canada (Newfoundland)

Historically the most famous origin in the world (Basques fished here in the 15th century), but the 1992 moratorium due to stock collapse changed everything. Fishing has partially reopened, but quantities are small. Canadian cod from Newfoundland, when found, is excellent: very cold waters, slow-growing fish, firm flesh.

Pacific (Alaska)

Pacific cod (Gadus macrocephalus) is a different species from Atlantic cod (Gadus morhua). It is smaller, less gelatinous, with less flavor and a softer texture. It is significantly cheaper and is widely used in processed products (fish sticks, surimi). It is not comparable in quality to Gadus morhua.

How Icelandic cod reaches Spain

The journey of cod from Iceland to your plate in Spain is a fascinating process that combines centuries-old tradition with modern logistics:

1. Catching: Trawlers or longliners catch cod in Icelandic waters. Longline (hook) cod is of higher quality because it suffers less physical damage.
2. Processing on board or in port: The cod is gutted, washed, and sorted by size. The most modern vessels process on board, ensuring maximum freshness.
3. Salting: The pieces are covered with sea salt (in alternating piles of fish and salt) for weeks. The salt extracts moisture and creates a hostile environment for bacteria. It is the same technique that has been used for over 500 years.
4. Drying (for dried cod): Some pieces are air-dried outdoors on wooden racks (stockfish) for 3-5 months. This is the oldest method, which produces extremely hard cod that is rehydrated in water. Others are dried in rooms with controlled ventilation.
5. Transport: Salted cod travels in refrigerated containers by ship from Reykjavik to Spanish ports (Barcelona, Bilbao, Vigo). The journey takes 5-7 days.
6. Distribution: Specialized importers receive the containers and distribute to markets, shops, and restaurants. In our case, we personally select each batch that enters the Mercat del Ninot.

How to identify good Icelandic cod

In the market or store, these are the signs of top-quality Icelandic cod:

• Color: Uniform ivory-white, without yellow spots or dark areas. If salted, the surface is white with visible salt crystals.
• Texture: Firm to the touch. When pressed with a finger, it should spring back. If it sinks and doesn't recover, the cod has been around too long or is not of good quality.
• Smell: Of clean sea. Never ammonia, rancid, or "old fish." Good quality salted cod has a pleasant, even appetizing smell.
• Thickness: The best pieces have loins 4-5 cm thick at the widest part. Thin cod (less than 2 cm) is probably from a young fish or from a warmer water area.
• Skin: Thick, silvery or light gray, firmly attached to the flesh. Thick skin = more gelatin = better pil pil.
• Certified origin: Look for the MSC (Marine Stewardship Council) seal or the Iceland origin indication. Serious distributors certify the origin.

How to cook Icelandic cod to take advantage of its quality

Cod of this quality deserves techniques that respect its texture and flavor:

• Confit at 65 °C: The technique that best showcases the flaky texture of Icelandic cod. 12-15 minutes in warm olive oil. It is the quintessential restaurant preparation.
• Pil pil: The abundant gelatin of Icelandic cod makes the pil pil emulsify almost by itself. The thick skins release collagen that naturally thickens the sauce.
• Low-temperature oven baking: 120 °C for 20 minutes. Gentle heat maintains juiciness and flaky texture.
• Brandade: The high proportion of gelatin in Icelandic cod creates a naturally creamy brandade, without the need to add too much potato or cream.
• Avoid: Aggressive frying, prolonged boiling in water, or microwave. Any method that dehydrates or breaks the flakes wastes the quality of the product.
