Chef suggested:

1, stir-fry the tomato pieces in the pot until the tomatoes are loose, and then boil the water, which can reduce the cooking time and make the tomatoes easier to dissolve in the soup.

2. When the tomato soup is seasoned, add some sugar to combine the strange taste. If you hate sour soup, you can add more sugar to taste it.

3. Beef and mutton can be replaced by beef tendon or beef show, but it takes a long time to cook. Tomatoes and potatoes can only be stewed until they are soft when the beef tendon or beef show becomes more brittle and rotten.

4. After the tomato and potato soup is stewed, add the marinated tender beef and cook until the beef and mutton fade, otherwise the tender beef will be overcooked.

5, use tomatoes to quench thirst, strengthen the spleen and nourish the stomach, clear heat and lower blood pressure. Put tomatoes, potatoes, beef and mutton in the soup. Most of the cooked tomatoes and potatoes are dissolved in the soup, which makes the soup thick and smooth and has a shallow strange smell. Winter coincides with the flu season. Drinking potato, tomato and beef soup regularly can increase the body's resistance and prevent the flu.
