Mackerels

The mackerels are small relatives of the tunas. The mackerel proper is a native of the North Atlantic and Mediterranean, typically 18 inches/45cm long and 1–2 lb/0.5–1 kg. Like the tuna, it’s an energetic predator, with a large complement of red fibers, active enzymes, and an assertive flavor. It is usually netted in large numbers and sold whole, and deteriorates rapidly unless immediately and thoroughly iced.
