What is Una-don?
Unadon is an abbreviation for unagi-donburi , meaning "eel bowl". It consists of a donburi type large bowl filled with steamed white rice, and topped with fillets of eel ( unagi ) grilled in a style known as kabayaki , which is similar to teriyaki . The fillets are glazed with a sweetened soy-based sauce, called tare and caramelized, preferably over charcoal fire. The fillets are not flayed, and the grayish skin side is placed faced down. Sufficient tare sauce is poured over so that some of it seeps through the rice underneath. By convention, pulverized dried berries of sanshō (called Japanese pepper, although botanically unrelated) are sprinkled on top as seasoning. There are two styles of grilled eel, the topic of which is covered more precisely under kabayaki . Essentially, in the Kantō region style, the eel is steamed before being grilled with sauce, which makes the eel more tender. The other is the Kansai region style, which is grilled without steaming.
