1Choose a lean cut of beef. Slice against the grain into thin pieces (2-3 mm thick). For easier slicing, freeze the beef for about an hour before cutting.
2In a bowl, mix baking soda, sugar, salt, MSG, and ice water until dissolved.
3Add the beef and mix by hand until it feels sticky. Gradually add the ice water in 4-5 batches, mixing after each addition until the beef is hydrated and shiny.
4Add the egg white and mix evenly. Then, add cornstarch and coat the beef evenly.
5Cover and let it rest for 30 minutes.
6In a bowl, combine soy sauce, sugar, white pepper, dark soy sauce, Shaoxing wine, oyster sauce, water, and cornstarch. Mix until smooth and set aside.
7Heat oil in a pan. Add the marinated beef and sear on both sides until the surface changes color. Cook to medium-well (70-80% done). Remove the beef and set aside to drain.
8In the same pan, add ginger slices and cook until fragrant. Next, add garlic slices and the white part of the green onions. Stir-fry until aromatic.
9Return the cooked beef to the pan and pour in the sauce. Turn the heat to high and stir-fry quickly, ensuring the beef is evenly coated.
10Sprinkle the green onion tops into the pan and give it a quick stir.
11Serve immediately and enjoy your flavorful ginger and scallion beef stir-fry!
