I made this dish using dried king oyster mushrooms which have a nice flavour and texture instead of using expensive porcini mushrooms. It's as good as the one with porcini mushrooms.
Highly nutritious and delicious dried vegetables are a current boom in my household Dried king oyster mushrooms are especially popular and I always have them on hand.
Please use the dried king oyster mushrooms without squeezing the water out because they contain lots of umami. Please use the water from rehydrating them as well since it also contains umami.
Enjoy Japanese food around the world.
