How do you preserve mackerel?

Mackerel can be preserved through several methods, including smoking, pickling, and freezing. Smoking enhances its flavor and extends shelf life by reducing moisture content and inhibiting bacterial growth. Pickling involves immersing the fish in a solution of vinegar, salt, and spices, which also helps preserve it while adding a tangy taste. For longer-term storage, mackerel can be cleaned, filleted, and frozen, maintaining its quality for several months.
