1. The pig lungs I bought today must be cleaned with trachea throughout.
2. Insert a tube into the pig’s lung trachea and keep flushing in
3. Fill it until the lungs of the pig swell up, and then drain the water in the lungs, and the blood will flow out with it. In the process of filling the water, keep slapping the lungs of the pig.
4. This is the lung of a pig after being filled five times. It's very clean.
5. Then put a needle down on the edge of the pig's lungs. There are also places where there is a small amount of blood. Pinch the water pipe with your hand and let the water fill it in. Water will flow out from the hole to bring out the remaining blood.
6. Finally wash the clean cross section.
7. The pig lungs must be cut into large pieces. The lungs shrink very sharply. When the water is blanched in the pot, there will be a lot of foam the first time. Cook it for ten minutes and remove it and clean it. Change the pot to clean water and continue cooking. After cooking, take them out and place them in the refrigerator to freeze.
