This dish is all about pork and napa cabbage, cooked in a minimum way. They are simply layered to pack in a donabe, with a small amount of water and sake. There is not even dashi or salt. You can top them with some sliced ginger and mushrooms, and gently simmer for 25 – 30 minutes. The result is a tasty treat rich in umami, and it looks beautiful, too. The soup is also packed with all the natural flavors from the ingredients, so make sure to enjoy it with the dish, too.
