Step 1

Bring about 2 quarts water to a boil in a large pot over high heat. Add noodles, return to a rolling boil and cook according to package directions until al dente. Carefully pour the noodles into a colander and rinse with several changes of cold water. Shake well to remove excess water. Return the noodles to the unwashed pot, add sesame oil and toss until well combined. Set aside.

Step 2

Place pork in a shallow bowl. Add cornstarch, 1 teaspoon rice wine (or sherry), 1 teaspoon soy sauce and 1/4 teaspoon salt; toss well to coat. Combine chile-garlic sauce and the remaining 1 tablespoon each rice wine (or sherry) and soy sauce in a small bowl.

Step 3

Heat a 14-inch flat-bottomed wok over high heat until a bead of water vaporizes within 1 to 2 seconds of contact. Swirl in 1 tablespoon peanut (or vegetable) oil and add ginger; using a metal spatula, stir-fry until the ginger is fragrant, about 10 seconds. Push the ginger to the sides of the wok, carefully add the pork and spread evenly in one layer. Cook undisturbed for 1 minute. Stir-fry until the pork begins to brown, about 1 minute. Add bok choy and mushrooms; stir-fry until the bok choy is just wilted but the pork is not cooked through, about 1 minute. Swirl the remaining 1 tablespoon peanut (or vegetable) oil into the wok. Add the noodles and stir-fry until just combined, about 15 seconds. Stir the soy sauce mixture and swirl it into wok. Add scallions, cilantro and the remaining 1/4 teaspoon salt; stir-fry until the pork is cooked through and the noodles are heated through, about 2 minutes.
