How's the beef going soft? First, the choice is to buy beef, which is thin and tender, such as a ridge, an outer ridge, etc.; to cut beef is to cut it in reverse and as thin as possible; and the next step is to pick it up and mix it with salt, raw and starch, and then add a little water grab to feed the beef, set it to 10 minutes, and put some oil on it before it goes out. Fried beef is made of a fire, mixed with starch, which forms a membrane on the face of the beef and effectively locks the water in the beef, so that the roasted beef is softer and softer。
