Method

1. 1 Slice the beef thinly across the grain, then marinate it with cornstarch, soy sauce, and a little water for 20 minutes.
2. 2 Marinating the meat with cornstarch mixed with water helps retain moisture; beef stir-fried without this marinade will be tough and dry.
3. 3 Heat the pan until it smokes, then stir-fry the meat for 90 seconds and remove it immediately.
4. 4 Sauté the onions, garlic, and mushrooms for 2 minutes until the mushrooms are slightly wilted.
5. 5 Season with oyster sauce, cornstarch, and a little water, then simmer for 40 seconds until the sauce thickens.
6. 6 Add the meat, then add the chopped scallions, shake the pan for 20 seconds, and sprinkle with pepper.
