Horse mackerel, also known as Aji in Japanese cuisine, is a saltwater fish celebrated for its firm, oily flesh and distinctive flavor. Its slender, silver-skinned body and sharp scutes along its lateral line make it easily identifiable. The taste of horse mackerel is often described as rich, slightly grassy, and more pronounced than other types of mackerel. Fresh horse mackerel is prized for its versatility and is a favorite among seafood enthusiasts.

Fresh horse mackerel is best used as soon as possible. Store it in the refrigerator, wrapped tightly in plastic wrap or in an airtight container, and place it on a bed of ice if possible. It should be consumed within 1-2 days for optimal quality. For longer storage, horse mackerel can be frozen. Wrap it tightly to prevent freezer burn, and it can be stored for up to 2-3 months.
