Tofu and Shimeji Mushroom with Oyster Sauce 豆腐としめじのオイスターソース

We had two packages of tofu 豆腐 and one package of shimeji mushroom しめじ which I needed to use fairly soon. I remembered seeing a YouTube episode of a tofu and shimeji dish.  I winged it from my memory so this may not be exactly the same dish. In any case, it was a good dish. It could be on rice but I seasoned it lightly and it is perfect as a drinking snack.

Ingredients:
1 package of tofu (I used house-brand semi-firm tofu which is currently our favorite tofu), cut into small rectangles, blanched, and drained well.
1 package (150gram) of brown shimeji mushrooms, bottom cut off and tops separated
2 tbs finely chopped shallot or onion
1 tbs finely chopped ginger
1 tbs finely chopped garlic
2 scallion, finely chopped
Salt and pepper to taste
2 tbs vegetable oil with 1/4 tsp dark sesame oil
1tbs oyster sauce
2 tsp soy sauce (I used x4 concentrated Japanese noodle sauce)
2 tbs sake
1/2 cup chicken broth
1 tsp potato starch mixed with 1tbs sake or broth or water (slurry)

Directions:
Add half of the oil in a non-stick frying pan on medium heat. Add the tofu and brown one side (3-4 minutes) and turn over and brown the other side for 2-3 minutes, set aside
Add the remaining oil to the same pan, add the shallot, ginger and garlic. Sauté for a few minutes until fragrant. Add the shimeji mushroom and sauté until the mushroom become soft (a few minutes), season with salt and pepper. Add back the browned tofu and mix gently.
Add the sake, oyster sauce, soy sauce and mix.
Add the chicken broth and simmer. Taste and adjust the seasoning (more oyster sauce or soy sauce)
Stir in the potato starch slurry and mix well until it starts boiling.
Add more sesame oil if so desired (optional)
Add the scallion

I prefer the seasoning for Mapo tofu. I can make the same dish with the seasoning of Mapo tofu. As to the browning the tofu, I am not sure it is a great improvement. The time and effort to brown the tofu, this process may not be worth it. But this is a good dish in its own right.
