Pan-Seared Salmon: Skin On Or Off?

Whether or not to eat the skin on pan-seared salmon is a hot topic for foodies. It is generally considered safe to eat, and it is often served with the skin on in restaurants. The skin contains a high concentration of omega-3 fatty acids, vitamins B and D, and minerals like selenium, phosphorus, and niacin. Eating the skin can also add a crispy texture to the dish and protect the delicate flesh from drying out or burning. However, some people may choose to remove the skin due to its distinct 'fishy' taste or because of concerns about chemical contamination.

The skin is a good source of omega-3 fatty acids, vitamins B and D, and minerals like niacin and phosphorus

Salmon skin is a good source of omega-3 fatty acids, vitamins B and D, and minerals like niacin and phosphorus. These nutrients are essential for human health and offer a range of benefits.

Omega-3 fatty acids, for example, are known to reduce triglyceride levels and protect the heart against specific risk factors for heart disease, such as high blood pressure. They may also help protect the brain from degeneration, keep the skin supple and healthy, and protect the eyes from age-related macular degeneration. The body cannot produce omega-3 fatty acids, so they must be obtained through diet. Salmon skin contains an even higher concentration of these fatty acids than the flesh of the fish.

Vitamins B and D are also important for overall health and well-being. Vitamin B supports brain development and cognitive function, while vitamin D helps maintain bone health and supports the immune system.

Niacin is a type of B vitamin that plays a crucial role in energy production, metabolism, and healthy skin and nerve function. Phosphorus, on the other hand, is a mineral that works closely with calcium to support bone health. It is also involved in energy production and protein synthesis in the body.

By keeping the skin on during cooking, you can retain more of these valuable nutrients and healthy oils in your meal. Not only does this add nutritional benefits, but it can also enhance the flavour and texture of your dish.

However, it is important to note that the quality and source of the salmon are crucial factors to consider when deciding whether to eat the skin. Salmon skin can accumulate pollutants, such as polychlorinated biphenyls (PCBs) and methylmercury, from the water and other fish they eat. These contaminants have been linked to adverse health effects, including cancer and birth defects. Wild-caught salmon is generally considered a safer option, as it tends to have lower levels of these contaminants.

It's recommended to cook the salmon 90% of the way on the skin side

Cooking salmon is an intimidating task, as it is an expensive protein to mess up. However, there is a secret to achieving the perfect pan-seared salmon with a crispy skin and a moist interior.

Firstly, it is important to prepare the salmon skin before cooking. This involves descaling the skin and thoroughly drying the exterior with paper towels. Removing the scales ensures an optimal eating experience, as they can ruin the texture of the skin. Drying the skin is crucial, as browning can only occur once all the moisture has been cooked off.

Next, the pan should be preheated for 3-5 minutes, depending on the type of stove. The pan should be hot enough for the oil to shimmer, but not smoke violently. A stainless steel or cast iron skillet is recommended for the best sear. The salmon should then be seasoned with salt right before placing it in the pan. This is because salt draws out moisture, so seasoning earlier may prevent an optimal sear. The salmon should be placed skin-side down in the hot oil, ensuring that the oil does not splash.

The secret to achieving the perfect crispiness is to cook the salmon for 90% of the time on the skin side. This ensures that the skin is thoroughly crisped, while the flesh side is cooked gently. The cooking time will depend on the thickness of the fillets, so a meat thermometer should be used to check for doneness. For salmon that is about an inch thick, the skin side should be cooked for around 5 minutes on medium heat, until it is golden brown and crispy. The salmon should then be flipped and cooked for an additional 15-30 seconds on the other side.

Finally, the salmon should be plated skin-side up to retain the crispiness of the skin and prevent it from becoming soggy. This method of cooking salmon ensures a tasty contrast between the crispy skin and the tender flesh.

The skin can be removed by placing the salmon skin-side down, sprinkling salt towards the tail end, and using a sharp knife to cut between the skin and flesh

Removing the skin from salmon is a simple process. Firstly, place the salmon skin-side down on a flat surface or chopping board. Sprinkle some salt towards the tail end of the salmon to gain a better grip and prevent the salmon from sliding.

Holding the tail end, use a sharp knife to begin cutting between the skin and the flesh, starting opposite from the tail end. Continue to hold the tail end tightly and cut along the entire length of the filet, being careful to avoid your fingers and not cut through the skin.

If you are new to removing salmon skin, it may be beneficial to use a slightly dull chef's knife. This is because if your knife is very sharp, you may inadvertently cut through the skin when you press down on it.

Once you have cut along the entire length of the filet, remove and discard the salmon skin, or save it for a special treat! For example, you can remove the skin and slice it into long strips to make a tasty and healthier version of bacon.

When pan-searing salmon, cook the skin side down to make it crispier and form a protective coating for the delicate flesh

When pan-searing salmon, cooking the fish skin-side down for most of the cooking time is the key to achieving a crispy skin and a gently cooked, tender flesh.

The skin of the salmon contains a thick layer of fat that needs to be rendered to get the skin crisp and pleasant. Cooking the salmon with the skin side down allows this fat to be fully rendered while insulating the delicate flesh from the direct heat of the pan. This technique also helps to prevent the fish from drying out.

To achieve the perfect pan-seared salmon, start by drying the salmon skin thoroughly with paper towels. This step is important as moisture left on the surface of the fish can interfere with achieving a good sear.

Next, preheat a thin layer of oil in a stainless steel, cast iron, or carbon steel skillet over medium-high heat until shimmering. It is important to preheat the pan and oil to prevent the salmon from sticking to the pan. Once the pan is hot enough, carefully add the salmon, skin-side down, lowering it gently and confidently into the pan.

Cook the salmon for most of the cooking time with the skin side down. The exact cooking time will depend on the thickness of the fillet, but a large fillet will take about six minutes to reach a medium-rare center. The skin should be nice and crisp by the time the salmon is ready to flip.

Finally, flip the salmon and give it a quick kiss of heat on the other side, about 15 to 30 seconds, before serving.

The salmon skin may be contaminated by chemicals called polychlorinated biphenyls (PCBs) and methylmercury

Salmon skin is generally safe to eat and offers health benefits, such as a reduced chance of heart disease, due to its high concentration of omega-3 fatty acids. However, it is important to consider the origin of the salmon before consuming the skin. Salmon skin may be contaminated by chemicals called polychlorinated biphenyls (PCBs) and methylmercury.

PCBs are industrial chemicals that were banned after being linked to adverse health effects in 1979. They are known carcinogens and have been associated with negative effects on the nervous, immune, and endocrine systems. Methylmercury is also toxic to humans and has been linked to birth defects. These chemicals accumulate in salmon through their food and the water they swim in. The longer a salmon is exposed to these chemicals, the higher the concentration of these contaminants will be.

Farmed salmon, particularly those from the Atlantic Ocean, tend to have higher levels of contamination. Wild-caught salmon, especially from the Pacific Ocean, is a safer option. When consuming farmed salmon, it is recommended to limit intake to no more than one meal per month to reduce exposure to these harmful chemicals.

To minimise the risk of consuming contaminated salmon skin, choose wild-caught salmon from reputable and clean water sources. Additionally, trimming the fat from the fish before cooking can help reduce PCB exposure.
