Tools/ingredients: 800g beef, 2 tomatoes, half onion, proper amount of salt, proper amount of cooking oil, half onion, ginger 1 slice, 2 aniseed, 2 cinnamon 1 slice, 2 fragrant leaves, 6 hawthorn slices, 3 dried peppers, 2 tablespoons soy sauce and 2 ml oyster sauce.

1, prepare all the ingredients. Cut the beef into slightly larger pieces. Soak the beef pieces in clear water for 2 hours, changing the water several times in the middle until the water becomes clear and bloodless.

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

3. Prepare the seasoning for stew. Peel the onion, wash and cut into sections, and cut the ginger into thick slices.

4. Put a proper amount of water into the pot, and put cold water into the pot. After boiling, you will see a layer of blood foam floating on the surface of the beef, and remove the blood foam with a spoon.

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

6. Stir-fry the juice, add the beef pieces and stir well.

7. Add 2 tablespoons of soy sauce, 1 tablespoon of oil and stir well, and add appropriate amount of water. Don't add salt first. When meat meets salt, protein will solidify quickly, making it difficult to taste, and the meat will harden easily.

8. Install the electric pressure cooker and switch to the first gear of "Beef". If you don't have this gear, you can change to another gear for about 25 minutes.

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