What is the black and white mushroom soup?

Why is Bailuobu cooked with mushrooms and the soup is black?

Raw materials:

Sparerib, onion, ginger, garlic, pepper, aniseed and fragrant leaves;

Pleurotus ostreatus, straw mushroom, Coprinus comatus, red ear and white radish.

Steps:

1 Cut onion, slice ginger and garlic, soak chicken fir for more than 20 minutes, wash, and wash other mushrooms.

2 cut the ribs and wash them. The purpose is to remove the blood from the meat, so that the cooked soup is good in color, more delicious and has no fishy smell.

Add cold water to the casserole, add meat and all seasonings, cook for ten minutes on high fire, and then simmer on low heat.

After about an hour and a half, add salt and monosodium glutamate to taste.

Boil the fire for another ten minutes, and then you can turn it off.

Tips:

1 Due to the loss of water during cooking, it is difficult to master the amount of salt in the early stage. Adding salt too early makes the meat aging and difficult to cook, so it is more appropriate to add salt ten minutes before cooking.

After adding salt, the fire must be boiled for ten minutes, so that the salt can dissolve and penetrate better, so that it will not have salty taste.

Termitomyces has a heavy taste, so it must be fully soaked before use, so as not to overshadow the delicacy of the broth, while retaining a good elastic taste.

Mushrooms are not all used for eating, but for extracting nutrients such as amino acids and adding flavor to soup, so they are added in the morning.

At most, one kind of mushroom with special fragrance can be added, such as red ear, while Pleurotus ostreatus, Volvariella volvacea and Coprinus comatus are not heavy in taste, so they can be added to the soup together to enhance the umami flavor.

This will not make the soup taste messy and different.

If you like, you can also cut some white radish pieces and throw them in, which can eliminate the accumulation of food and make the sisters who are worried about obesity get a good balance.

It's best to use fresh mushrooms, and don't choose mushroom umbrellas that are too big, which is suspected of hormone growth.
