12 dried shiitake mushrooms, cleaned (or Wood Ear)

2 C. boiling water

1 T. garlic oil

3 T. peeled and finely grated fresh ginger

1 tsp. crushed red pepper flakes, or to taste

5 C. chicken broth

2 1/2 T. Japanese soy sauce

1/4 C. Chinese red vinegar,* or more to taste

Salt and freshly ground white pepper, to taste

3 T. cornstarch

3 T. cold water

1 large egg, lightly beaten

6 whole green onions, green tops only, very thinly sliced

3/4 tsp. toasted sesame oil

4 oz. firm tofu (bean curd), cut into 1/4-inch cubes

 

Trim the tenderloin, removing all fat and silver skin; place in the freezer until firm and partially frozen, about 30 to 45 minutes. Slice into 1/16-inch thick slices, and then cut crosswise into narrow strips. Refrigerate until needed. Place the shiitake mushrooms in a small bowl, and cover with the boiling water; set aside to rehydrate for about 30 minutes. Lift the rehydrated mushrooms out of the soaking liquid; strain the broth through a fine mesh sieve, and set aside until needed. Remove the stems from the shiitakes and discard; thinly slice the caps, and set aside until needed. Place a medium sauce pot over medium heat; add the garlic oil and heat through. Stir in the ginger and red pepper flakes and cook until the aroma is released, about 1 to 2 minutes. Add the chicken broth and simmer, covered, for 15 minutes. Add the reserved sliced mushrooms, mushroom soaking liquid, soy sauce, vinegar, salt and pepper, and bring to a simmer. Whisk together the cornstarch and water; add to the pot, then bring to the boil. Immediately reduce the heat, and simmer 5 minutes more. Drizzle the egg into the soup, stirring gently to make ribbons. Add the green onions, sesame oil, tofu and pork strips; return to a simmer, then immediately remove from the heat. Do not overcook or the meat will become tough. Taste the soup, and adjust the seasoning with salt, pepper, red flakes and vinegar; serve immediately. *Chinese red vinegar is made from rice and used primarily as a dip or in soups and sauces. It can be found at your local Asian market or online. Substitute red wine vinegar if you are unable to find it.
