Beef Lo Mein

Fill a large pot halfway with water and set over high heat, and bring to a rolling boil. Add the noodles and cook, stirring occasionally, until al dente, about 2 minutes. Drain, discarding the water, and set aside.

In a small bowl, stir together the soy sauce, sugar, and salt; set aside.

Set a large wok over high heat and add one tablespoons of the oil. When it begins to shimmer, add the beef and cook, stirring frequently, until evenly browned, 2–3 minutes. Transfer to a plate and set aside.

In the same wok, heat the remaining oil. Add the mushrooms and fry until golden brown, 2 minutes. Add the water chestnuts, bean sprouts and scallions, stir fry until aromatic, 2 minutes. Transfer to the plate of beef and set aside.

To the hot wok, add the stock. When it begins to simmer, add the reserved noodles and cook, using tongs, toss occasionally, until the liquid has almost completely evaporated, about 4 minutes. Add the reserved beef and vegetables and toss to combine. Add the soy sauce mixture and toss until the noodles are evenly coated. Transfer to a large plate and serve hot.
