Ingredients

1 pound boneless pork loin

Marinade:
2 tablespoons soy sauce
1 1/2 tablespoons rice wine or sake
1 teaspoon toasted sesame oil
2 teaspoons cornstarch
1/2 teaspoon crushed Szechuan peppercorns (optional)

Spicy Sesame Dressing:
8 cloves garlic
2 1-inch-square knobs fresh ginger, peeled
1 teaspoon crushed dried chiles or dried chile flakes
6 tablespoons Chinese toasted sesame paste (stirred well before adding)
4 tablespoons toasted sesame oil
5 tablespoons soy sauce
1/4 cup rice wine or sake
1 1/2 tablespoons Chinese black vinegar or Worcestershire sauce
1 1/2 tablespoons sugar
6 tablespoons chicken broth or water
1/2 pound thin egg noodles, such as angel hair or spaghettini
2 1/2 tablespoons canola or corn oil
2 cups minced scallion greens

Directions

Cut the pork loin into thin slices about 1/4 inch thick, then cut the slices into thin, matchstick-size shreds about 1 inch long. Put the shreds in a bowl, add the marinade and toss lightly to coat. Cover with plastic wrap and let the pork marinate for 1 hour at room temperature or longer in the refrigerator.

Put the Szechuan peppercorns (if using) in a skillet and toast over medium heat about 4 to 5 minutes, stirring occasionally until they are fragrant. Let them cool slightly and then crush into a powder with a rolling pin or mallet.

Drop the seasonings of the Spicy Sesame Dressing in descending order into the feed tube of a good processor fitted with a steel blade while the machine is running. Mix together to a smooth sauce. Add the peppercorn powder and mix. Pour into a serving bowl.

Bring 3 quarts water to a boil, add the noodles and cook about 5 to 6 minutes, or until near tender. Drain in a colander, rinse lightly to remove the starch and drain again thoroughly. Divide the noodles into six portions in soup bowls.

Heat oil in a wok or large skillet until very hot. Add the pork and stir-fry over high heat, about 2 1/2 to 3 minutes, until the meat changes color and is cooked. Scoop it into a colander to drain; then spoon it over the individual servings of noodles and sprinkle about 1/3 cup minced scallion greens on top of each. Ladle some Spicy Sesame Dressing over all, and serve.
