About Mackerel

Mackerel is the oiliest fish on this list, with a fat content that can exceed twenty percent in season. That makes it exceptionally tolerant: where halibut at 60 degrees is already dry, mackerel is still juicy.

That oil is also why mackerel works so well over direct heat and in the smoker. It renders while cooking and keeps the flesh moist, while the outside can take on colour and smoke without the inside suffering for it.

The downside of that same oil is that mackerel spoils quickly and turns strong-tasting when it is not fresh. You notice that in the smell and the firmness of the flesh sooner than in the cooking temperature; buy it fresh and use it the same day.

Measure a whole mackerel as you would trout: just behind the head, at the thickest part of the back, beside the bone. On fillets, simply measure the thickest point. Expect little carryover with this fish, as the portions are thin.
