This dish is my unique donabe version of popular Japanese dish, buri daikon (simmered yellowtail and daikon in soy based broth). Daikon is first sautéed in butter, then, once the yellowtail is added along with the lemon and mushrooms, they were steamed with sake and Ayu Fish Sauce. All made in one donabe, and this versatile Fukkura-san donabe effectively steam-fry the ingredients. The result is so aromatic, savory, and delicious. If yellowtail is not available, this dish can be made with other rich-flavor fish such as cod or sea bass. Ayu fish sauce gives the elegantly rich umami flavor, but it can be substituted with regular soy sauce, too.
