For this dish, soup is the most direct embodiment of the dish, so we must pay attention to the cooking method of sour soup. First put cooking oil in the pot, turn to high heat, add ginger slices and garlic slices and stir fry, then add chopped pepper, pepper and yellow Chili sauce and stir fry. When you smell hot and sour, it means that your Chili sauce and vinegar are basically enough. Of course, I usually habitually taste the soup, add pickled pepper water and a small amount of soy sauce to stir well, then add a proper amount of water, and finally add white vinegar according to my favorite taste. As for collocation, you will generally choose to add some Flammulina velutipes. Tender and smooth Flammulina velutipes can greatly increase the taste of sour soup fat beef, and you can also add some bean bubbles to make the soup of sour soup fat beef fully integrate into the bean bubbles, and the bean flavor of the bean bubbles will bring the ultimate experience to your taste buds.
