Unadon is a donburi dish that features grilled eel, called unagi, served over a bed of steamed rice and drizzled with a sweet and savory sauce. The eel is first marinated in a special sauce, then grilled until tender and slightly charred. The grilled eel is then placed on top of the rice and glazed with more sauce. Unadon is often garnished with pickled ginger and served with a side of miso soup. The rich and flavorful eel, combined with the fluffy rice, creates a luxurious and indulgent meal.
