Roast beef with potatoes is a very popular home-cooked dish, but if you want to cook it delicious and rotten, you need to pay attention to the following points:

1. Choose beef suitable for cooking: It is recommended to choose beef with tendons, which will make the beef worse and taste better.

2. Treat beef in advance: blanch beef in boiling water once, wash it with clear water to remove blood foam and impurities, and then cut it into appropriate sizes, so as to make beef more tasty.

3. Choose the right potato: Choose fresh potatoes with delicate texture, so that the burning effect is better.

4. Cooking time: The heat should be moderate. First, boil over high fire, then turn to low fire and cook slowly. At the same time, it is necessary to stir frequently to prevent the pot from sticking.

5. Seasoning: In the process of cooking, add a proper amount of salt, soy sauce, soy sauce, cooking wine and other seasonings according to the taste to enhance the color, aroma and taste of the dishes.

6. Mastering the cooking time: The cooking time should not be too long, otherwise the potatoes will be rotten and affect the taste.
