Juicy donabe Beef Rice for your stamina. I used a block of American Wagyu hanger steak and thinly sliced by hand. By marinating the beef for a short time with sake, soy sauce and black sugar, the meat comes out so tender like you braised it! I also used some smoked soy sauce to complement the bold flavor but you can use only regular soy sauce, too. Donabe makes this dish so complete in flavor and texture, and it was just so delicious that I ate almost half of the pot. Happy Donabe Life!
