Generally, the time to add soy sauce should be before serving.
Because the main function of soy sauce is to adjust the color rather than seasoning, it is basically enough to add soy sauce and stir-fry before serving. .
Of course, many friends like to put the soy sauce very early. In fact, this is not good, because if the soy sauce is placed earlier, the color will be dirty, and it should be gray-black. After stir-frying the food for a long time, the color of the food may turn into the color of mud.
The color looks unappetizing, and the taste is not very good. It has gone away from the original taste of fried meat, and there will be a strong soy sauce smell. Therefore, it is recommended that when frying meat, you should not add soy sauce in advance. It is best to wait until the last time it is taken out of the pan. The food produced in this way is both delicious and good-looking, and it will be very appetizing. Of course, whether you are eating fried meat or cooking other foods, it is better to put soy sauce at the end.
