My large donabe steamer, Mushi Nabe, works so hard all year round. Among my favorite preparations with this donabe is a steamed fish dish. This is Steamed Black Cod with Soy-Negi Sauce. I layered black cod with tofu and shiitake mushrooms in a bowl and steamed in the donabe steamer, and poured this aromatic soy & scallion sauce (with a great kick with la-yu oil) over it to enjoy. This dish takes little effort and is really flavorful,and it also keeps your body so warm. Feel free to substitute with different kinds of fish.
