Hot and Sour Vegetable Soup

• 1 small napa cabbage (1 1/2 lbs)
• 2 large leeks, white and light green parts only sliced lengthwise and rinsed well
• 1 12 tablespoons olive oil
• 2 12 tablespoons fresh ginger, peeled and minced
• 6 -8 ounces fresh shiitake mushrooms, stemmed and thinly sliced
• 14 cup rice wine or 14 cup sake
• 14 ounces firm tofu, halved crosswise and cut into 1/4 inch slices
• 8 cups chicken broth or 8 cups vegetable broth
• 2 12 tablespoons cornstarch
• 14 cup water
• 4 12 tablespoons black vinegar or 4 12 tablespoons Worcestershire sauce, more to taste
• 3 tablespoons soy sauce (to taste)
• 1 teaspoon toasted sesame oil
• 1 teaspoon kosher salt (to taste)
• 34 teaspoon fresh ground black pepper
• 1 large egg, lightly beaten

1. Cut the stem from the cabbage and discard; cut the remaining cabbage into 1 1/2 inch sections and place in a bowl near the stove.
2. Thinly slice the leeks, lengthwise; prepare the remaining ingredients and place them near the stove.
3. Heat oil in a large pot over medium high heat; add leeks and ginger and stir fry until fragrant, about 15 seconds.
4. Add the tougher, outer sections of the cabbage and the mushrooms, and toss lightly while cooking, 1 to 2 minutes.
5. Add rice wine, partially cover pot, and reduce heat to medium; cook until the wine nearly evaporates, about 5 minutes.
6. Add remainder of cabbage, tofu, and broth; bring to a boil.
7. Lower heat a bit and simmer 15 minutes.
8. Mix the cornstarch with the water, then slowly add to pot while stirring; cook over medium high heat until broth has thickened somewhat to the consistency of heavy cream.
9. Stir in black vinegar, soy sauce, sesame oil, salt, and pepper; taste and adjust seasoning.
10. Turn off heat and slowly add the egg, stirring slightly.
