Can be cooked like braised pork. First, heat the oil, add two or three spoonfuls of sugar to evoke the sugar color, then add 5- 10 dried red pepper, 10 garlic seeds and a proper amount of star anise peel, add beef and stir-fry until fragrant, and then add potatoes. Stir fry for a while and add salt, monosodium glutamate, chicken essence, soy sauce, a little cooking wine or white wine. Put a proper amount of water, and then cook in the pressure cooker for about half an hour until the potatoes are cooked. Then put it in the pot until the soup is dry. This is simple and delicious.
