Cook the noodles according to the package directions.
450 g fresh lo mein noodles
Drain well.
Dry the noodles thoroughly in a salad spinner, or by spreading them out on a baking sheet to let the steam escape.
Toss the noodles with a little oil so they don't stick together.
A little neutral oil
Stir-Frying
Heat the wok over medium-high heat until it is lightly smoking.
Add the oil for the vegetables.
1 tablespoon neutral oil
Add the cabbage, onion, and carrot.
90 g cabbage, 30 g onion, 30 g carrot
Stir-fry for 1 minute, until the vegetables are tender but still crisp.
Set the vegetables aside.
Return the wok to medium-high heat and add the oil for the beef.
2 tablespoons neutral oil
Add the marinated beef and press it into a single layer.
Let it sear without stirring until the first side is nicely browned.
Set the beef aside with the vegetables.
Return the wok to medium-high heat and add the oil for the aromatics.
1 tablespoon neutral oil
Add the ginger and garlic and stir-fry for 10 to 15 seconds, until fragrant.
1 tablespoon ginger, 1 tablespoon garlic
Immediately add the noodles.
Toss them with the aromatics until softened and well coated, lowering the heat if they start to stick.
Return the vegetables and beef to the wok.
Toss until everything is evenly distributed.
Push the noodles to one side of the wok.
Pour the Shaoxing wine directly onto the hot wall of the wok, not onto the noodles.
1 tablespoon Shaoxing wine
Toss the noodles with the wine.
Finishing
Push the noodles to one side of the wok again.
Stir the sauce to re-suspend the cornstarch.
Pour the sauce directly onto the wall of the wok, not onto the noodles.
Let it bubble for 15 to 20 seconds, until it thickens and caramelizes around the edges.
Turn off the heat.
Gently toss the noodles in the thickened sauce until well coated, without breaking them.
Add the green onions and bean sprouts.
2 to 4 green onions, 50 g bean sprouts
Toss well and serve immediately.
Notes
Light soy sauce adds saltiness, while dark soy sauce gives the noodles their caramel color. If you only have one type of soy sauce, use light for both: the noodles will be a little lighter in color. Shaoxing wine can be replaced with dry sherry, or with a little stock plus a splash of rice vinegar and a pinch of sugar.
