Instructions

1. Marinate the beef: Pour cooking oil, cornstarch, salt and black pepper over the beef. Use your fingers to gently massage the ingredients into the beef.
- 2
Allow the beef to marinate at room temperature for 30 minutes.
- 3
Prepare the sauce by combining soy sauce, water, rice vinegar, brown sugar and cornstarch. Set aside.
- 4
Heat 2 tablespoons of cooking oil in a wok over high heat.
- 5
As the oil is heating up, add the julienned ginger to the wok.
- 6
Stir-fry the beef in small batches. For each batch, spread the beef out in a single layer in the wok, then wait for a few seconds before flipping them over.
- 7
Remove the beef from the wok just as it starts to turn brown. Some pink is okay because it will finish cooking with the sauce. It should take less than a minute to fry each batch.
- 8
Return all of the beef to the wok, then pour the sauce over the beef.
- 9
Stir to combine all the ingredients. The sauce will start to thicken quickly.

Add scallions to the wok at the last minute. Give all the ingredients a good stir, then transfer the dish to a serving plate.
