The recipe for beef soup is as follows:

Tools/raw materials: 800 grams of beef, 2 tomatoes, half an onion, appropriate amount of salt, appropriate amount of cooking oil, half a green onion, 1 old ginger pieces, 2 aniseed, 1 small piece of cinnamon, 2 bay leaves, 6 hawthorn slices, 3 dried chili peppers, 2 tablespoons of light soy sauce, and 2 ml of oyster sauce.

1. Prepare all the ingredients. Cut the beef into slightly larger pieces. Soak the beef cubes in clean water for 2 hours, changing the water several times until the water becomes very clear and no blood color.

2. Wash the tomatoes and cut them into large pieces.

3. Prepare the seasonings used for stew. Peel, wash and cut the green onions into sections, and cut the ginger into thick slices.

4. Put an appropriate amount of water into the pot and put the beef pieces under cold water. After the pot is boiled, you will see a layer of blood foam floating on the surface of the beef. Use a spoon to skim off the blood foam.

5. Put a little cooking oil in the pot, put all the ingredients in the pot and stir-fry.

6. Stir-fry until the juice is released, add the beef cubes, and stir-fry evenly.

7. Add 2 tablespoons of light soy sauce, 1 tablespoon of oil, stir-fry evenly, and add an appropriate amount of water. Don't add salt first. The protein in the meat will solidify quickly when it encounters salt. Not only will it be difficult to taste, but the meat will also become hard.

8. Put in the electric pressure cooker and adjust it to the "beef" level. If this level is not available, you can adjust other gears. The time is about 25 minutes.

9. Then take it out and the delicious beef soup is ready.
