Steps:
1. Prepare 250g of beef. Beef is best served with tenderloin. You can ask the stall to cut it for you, or you can go home and cut it yourself. Be sure to cut against the grain and cut into thin slices.
2. Prepare a piece of ginger and an onion, clean it, cut it into pieces and put it in a bowl, then add a proper amount of warm water to turn the onion ginger into an onion Jiang Shui, and let it stand for about 10 minute.
3. Time is up, pour the onion, ginger and garlic into the beef. Note that there is only water, no onions and ginger. Start to "massage" the beef for about one minute, and knead the onion and Jiang Shui into the beef. This can remove the fishy smell without cooking wine.
4. Then start adding seasoning. Use this ordinary eating spoon, add half a spoonful of salt, half a spoonful of oyster sauce, half a spoonful of soy sauce, half a spoonful of sugar and a little pepper, and stir well.
5. Prepare a small bowl, add 2 tablespoons of starch, melt it with a small amount of water, pour it into the beef, and knead it evenly to form a slurry on the surface of the beef and wrap it.
6. Finally, pour a spoonful of vegetable oil, firmly lock the surface moisture of beef to prevent water loss, grab and mix for a while, cover with a layer of plastic wrap, and marinate for 15 minutes. Beef is tender, crisp and delicious, and can be fried in a pot. No other seasonings need to be added, just add salt according to the amount of side dishes.
