Unagi don is a Japanese eel rice bowl that pairs tender cooked eel with a glossy homemade unagi sauce for a rich sweet-savory meal. This recipe focuses on preparing eel for unagi don or unaju, then coating it with a sauce usually made from soy sauce, mirin, sake, and sugar until it becomes shiny, thick, and deeply flavorful. The eel is cooked or reheated until soft, then brushed with the sauce so the surface caramelizes slightly while the inside stays moist. As the glaze settles over the eel, it adds umami, sweetness, and a polished finish that works perfectly over warm steamed rice. The final bowl can be served with extra sauce, sansho pepper, pickles, or a simple soup, creating a classic Japanese-style dish with tender eel, fragrant rice, and a balanced homemade sauce.
