Step 1: Wash the bought beef with clear water, then put it into a small basin, add a proper amount of clear water to the basin, and let the beef soak in the basin for a while.

Tip: There will be a lot of blood and dust in the beef you just bought. If it is directly used for cooking, it is not only unsanitary, but also has a fishy smell. It is much better to put beef in clear water and soak it in bleeding water before frying.

Step 2: Soak all the blood in the beef, then wash the beef in clear water twice, then put it on the chopping block, cut it into thin and even pieces and put it in a small bowl, then add a proper amount of cooking wine, soy sauce and baking soda to the bowl and grab it evenly by hand.

Tip: This step is only to make the beef meat softer and more delicious. There is no need to over-marinate or add too much seasoning, especially baking soda, because too much baking soda will change the taste of beef and make it unpalatable.

Step 3: Mix beef with other seasonings evenly, then continue to add appropriate amount of sugar and starch into the pot, mix evenly again, and then let it stand and marinate for about 8 minutes.

Tip: Don't put too much sugar and starch. Too much sugar will make the fried beef too sweet and not delicious. If you put too much starch, the fried taste will be sticky. Just put a little starch. In addition, this step must stir the beef, starch and other seasonings evenly, so as not to let the starch appear "dead bumps".
