What is Ankimo (Monkfish Liver)?

Ankimo (あん肝) is a Japanese dish prepared from the liver (kimo, ) of a monkfish or anglerfish (ankou, 鮟鱇). It is also known as umi no foagura (海のフォアグラ) and is a delicacy that is very much sought-after in Japan. Ankimo is served as a starter in upscale restaurants that serve traditional Japanese food (washoku), Japanese multi-course haute cuisine (kaiseki ryori) or sushi. For the preparation, the blackmouth angler (ankou, アンコウ) and yellow goosefish (hon ankou, ホナンコウ), which are native to Japan, are preferred. More and more, their European and American relatives are also appearing in Japanese kitchens.

Ankimo as Ingredient for Sushi or Sashimi

Ankou are large and unappealing but extremely tasty, especially their liver. Ankimo's taste is very rich, less like fish, creamy but at the same time very light and tender. The soft texture gives a velvety feeling on the tongue and the high fat content makes ankimo melt in the mouth. Ankimo is often served with grated daikon radish with chili (momiji-oroshi, もみじおろし), finely chopped Japanese bunching onion (negi, ネギ) and/or a citrus-based seasoning sauce (ponzu, ポン酢). Unlike most Japanese sushi dishes, ankimo should not be combined with soy sauce, as it spoils the delicate taste of ankimo too much. It should be served cool, but slightly above refrigerator temperature.

Ankimo is not exclusive to Japanese cuisine. In France, ankimo is known as foie de lotte. In Spain, the monkfish liver is called Hígado de rape and is highly appreciated.

After the fish has been filleted, the liver is first rubbed with salt and rinsed with alcohol (sake, ). Carefully, the liver is freed from its large blood vessels, possibly parasites and membrane skin. It is then cooked in a cylinder made of aluminum foil. Ankimo is rich in vitamins, protein and minerals. However, mercury compounds ingested in the fish's diet also accumulate in the liver, so it is best to refrain from eating large quantities of ankimo.

Best Season

Traditionally, ankimo is a winter recipe in Japan, outside Japan it is often to be found in high-class sushi restaurants all year round.
