Instructions
- 1
Marinate the beef
- 2
Cut the beef filets into cubes, about ¾inch (2cm) in size. Then put them into a bowl.
- 3
Add light soy sauce, Shaoxing rice wine, water, cornstarch, and salt. Rub and swirl until the liquid is fully absorbed.
- 4
Pour in oil and mix to coat the beef cubes evenly. Leave to marinate while preparing other ingredients.
- 5
Mix the sauce
- 6
In a small bowl, mix light soy sauce, dark soy sauce, stock(or water), cornstarch, black pepper, sugar, and salt. Set aside.
- 7
Sear the beef
- 8
Heat a wok over high heat until lightly smoking (see note 2 if using non-stick cookware). Pour in 1 tablespoon of oil and swirl to coat a large area. Put in the beef cubes and spread them in a single layer.
- 9
When the bottom side touching the wok turns pale, flip and toss the beef to sear the other sides.
- 10
Once all the cubes have lost the pink color on the surface (still pink inside), transfer the beef out to a plate.
- 11
Stir-fry the dish
- 12
Pour the remaining 1 tablespoon of oil into the vacant wok. Add the halved garlic cloves first. Sizzle until they turn golden on the edge.
- 13
Add the mushroom and bell pepper. Toss them for about 30 seconds.
- 14
Return the seared beef to the wok and stir fry for one more minute until the meat is almost fully cooked.
- 15
Pour in the sauce mixture (stir it very well beforehand). Give everything a final toss until the sauce thickens to the desired consistency.
