Moray eel food is a local food in Kochi 高知 Japan. It is unique in texture and little chewy. I sometimes eat it because it's tasty.
Aquarium (in Japanese)
Deep Fried Moray Eel ウツボから揚げ
Seared Moray Eel ウツボたたき
It is seared after it is boiled or steamed. It is often served with sliced onion and garlic.
This place is a large food court and well-known as a sightseeing place in Kochi 高知.
Moray Eel Jerky ウツボジャーキー
Sake / beer and moray eel jerky match very well.
I bought it at this place in 2018, but I'm not sure if they still have the product in stock.
