2. wrap egg whites. After cutting the beef slices, add an appropriate amount of egg white, stir well, let stand for 3 minutes and then fry. In the frying process, the egg white mixture is denatured and solidified by heat, thus reducing the loss of water and nutrients in beef and making the meat tender and tender. Egg white wrapping pulp is generally used with starch wrapping pulp, and the effect is better.
3. add beer. It is also a good choice to pour a proper amount of beer on beef, marinate for 3 minutes, and then fry it. Because the enzymes in beer can decompose some protein in beef, thus increasing the tenderness of beef. However, due to the low enzyme content in beer, the "tender meat" effect of this method is not as good as the first two methods.
finally, if you want to stir-fry fresh beef, you'd better choose lean meat and tender meat when buying beef, such as tenderloin and tenderloin. When cutting beef, you should also pay attention to cutting against the grain of the meat. The thinner you cut, the better, so that the fried beef will be more tender.
