Stewed beef can be cooked in a purple casserole. If you use a pressure cooker, beef will go bad and not taste good. The pressure cooker can really stew beef in a short time. However, the stew in the pressure cooker is not fragrant and loses a lot of nutrients. The working principle of purple casserole is to cook food very slowly at low temperature, and when the pot reaches a certain temperature, it will maintain a stable temperature.

500g beef, appropriate amount of onion, 50g soy sauce, appropriate amount of salt and sugar, aniseed, fennel and a little pepper.

Cut the beef into cubes of 1.5cm, wash it with boiling water and take it out. Clear soup for use.

Put the meat into the soup, add salt, soy sauce, sugar and green onions, and put the aniseed, fennel and pepper into a bag and seal. Cover the pot and simmer for about 3 hours. Serve.
