HOT AND SOUR INGREDIENTS RECIPES

Steps:

• Toss pork with dark soy sauce in a bowl until pork is well coated.
• Soak black and tree ear mushrooms in 3 cups boiling-hot water in another bowl (water should cover mushrooms), turning over black mushrooms occasionally, until softened, about 30 minutes. (Tree ears will expand significantly.) Cut out and discard stems from black mushrooms, then squeeze excess liquid from caps into bowl and thinly slice caps. Remove tree ears from bowl, reserving liquid, and trim off any hard nubs. If large, cut tree ears into bite-size pieces. Stir together 1/4 cup mushroom-soaking liquid (discard remainder) with cornstarch in a small bowl and set aside.
• Meanwhile, soak lily buds in about 1 cup warm water until softened, about 20 minutes, then drain. Trim off tough tips of lily buds. Cut lily buds in half crosswise, then tear each half lengthwise into 2 or 3 shreds.
• Cover bamboo shoots with cold water by 2 inches in a small saucepan, then bring just to a boil (to remove bitterness) and drain in a sieve.
• Stir together vinegars, light soy sauce, sugar, and salt in another small bowl.
• Heat a wok over high heat until a bead of water vaporizes within 1 to 2 seconds of contact. Pour peanut oil down side of wok, then swirl oil, tilting wok to coat sides. Add pork and stir-fry until meat just changes color, about 1 minute, then add black mushrooms, tree ears, lily buds, and bamboo shoots and stir-fry 1 minute.
• Add broth and bring to a boil, then add tofu. Return to a boil and add vinegar mixture. Stir cornstarch mixture, then add to broth and return to a boil, stirring. (Liquid will thicken.) Reduce heat to moderate and simmer 1 minute.
• Beat eggs with a fork and add a few drops of sesame oil. Add eggs to soup in a thin stream, stirring slowly in one direction with a spoon. Stir in white pepper, then drizzle in remaining sesame oil and divide among 6 to 8 bowls. Sprinkle with scallions and cilantro before serving.

Steps:

• Put the wood ears in a small bowl and cover with boiling water. Let stand for 30 minutes to reconstitute. Drain and rinse the wood ears; discard any hard clusters in the centers.
• Heat the oil in a wok or large pot over medium-high flame. Add the ginger, chili paste, wood ears, bamboo shoots, and pork; cook and stir for 1 minute to infuse the flavor. Combine the soy sauce, vinegar, salt, pepper, and sugar in a small bowl, pour it into the wok and toss everything together - it should smell really fragrant. Pour in the Chinese Chicken Stock, bring the soup to a boil, and simmer for 10 minutes. Add the tofu and cook for 3 minutes.
• Dissolve the cornstarch in the water and stir until smooth. Mix the slurry into the soup and continue to simmer until the soup thickens. Remove the soup from the heat and stir in 1 direction to get a current going, then stop stirring. Slowly pour in the beaten eggs in a steady stream and watch it spin around and feather in the broth (it should be cooked almost immediately.) Garnish the hot and sour soup with chopped green onions and cilantro before serving.
• Put the chicken in a large stockpot and place over medium heat. Toss in the green onions, garlic, ginger, onion, and peppercorns. Pour about 3 quarts of cold water into the pot to cover the chicken by 1-inch. Simmer gently for 1 hour, uncovered, skimming off the foam on the surface periodically.
• Carefully remove the chicken from the pot and pass the stock through a strainer lined with cheesecloth to remove the solids and excess fat. Cool the chicken stock to room temperature before storing in the refrigerator, or chill it down over ice first.
• Yield: About 2 quarts
