What is Aji?
In Japan, “Aji” (鯵) is the name for horse mackerel, a popular fish in Japanese cooking. Aji has a mild flavor and offers great versatility, allowing cooks to prepare it in various ways. You can enjoy it grilled, fried, or raw as sashimi. The name “horse mackerel” reflects its tasty qualities, and people love its delicious flavor whether they eat it fresh, grilled with salt, or fried.
History
Horse mackerel has been a part of the Japanese diet since ancient times, with its history going back as far as the Jomon period. People often processed aji into dried fish that lasted a long time, and they even presented it to the Imperial Court, which is far from the sea. It wasn’t until the Edo period when it started appearing on the tables of ordinary people, but it has continued to be a staple of the Japanese diet for several hundred years since then.
Types of Aji
In Japan, there are three main types of horse mackerel: Japanese horse mackerel, brown horse mackerel, and striped horse mackerel.
- Japanese horse mackerel is the most common and is found from Hokkaido to Kyushu. It is small, about 30 cm long, with translucent, pale flesh that’s great for sashimi or nigiri sushi. However, it spoils quickly, so it should be eaten very fresh if served raw.
- Muroaji is another type found mainly in Kyushu. It’s larger, about 40 to 50 cm long, with darker flesh due to its high blood content. Because it spoils quickly, it’s not widely available and is mostly eaten locally.
- Shimaaji, or striped horse mackerel, is less common and has distinctive yellow stripes. Chefs and diners prize Shimaaji for its clear, beautiful flesh and delicate flavor, which explains why high-end restaurants often feature it. Connoisseurs especially value larger specimens of Shimaaji.
