Soak the tofu in water and cut it into small pieces. Cut the carrots and the shiitake into small pieces as well. Heat sesame oil in a pot and then add in the ginger. Next, add the meat in and stir fry until aromatic. Then you can add in the carrots and shiitake and stir fry again.
Next add in the dashi stock, sugar, mirin, sake, soy sauce and tofu. Cover with a lid and cook down on low heat until the liquid disappears.
This is version is made with ground pork, shimeji, edamame, and then topped at the end with a beaten egg. This variation is also delicious.
Story Behind this Recipe
My mother taught me how to make a basic simmered freeze dried tofu, and I just modified it slightly.
I don't really have any hints but as for the ground meat, you can use either chicken or pork. You can sub shimeji mushrooms for the shiitake and they are delicious. In the version with the edamame, it's great when topped at the end with a beaten egg.
