Chinese Hot and Sour Soup

During my first winter in Beijing as an exchange student, I caught a terrible cold. My host mother immediately set to work making hot and sour soup, insisting it was medicinal. The complex flavors – sharp vinegar, warming white pepper, and umami mushrooms – cut through my congestion, and I was instantly converted.

Years later, this soup remains my go-to remedy for winter blues and sniffles. While authentic versions require specialty ingredients, this adapted recipe captures the essential character using components more readily available in Western supermarkets. Each spoonful transports me back to that tiny Beijing kitchen where I first discovered food could be both comfort and cure.

Ingredients:

• 8 cups chicken stock
• 8 dried shiitake mushrooms, rehydrated and sliced
• 1/2 cup bamboo shoots, julienned
• 1/4 cup dried wood ear mushrooms, rehydrated and sliced
• 1/2 block firm tofu, cut into 1/4-inch strips
• 1/4 cup dried lily flowers, rehydrated and ends removed (optional)
• 2 tablespoons vegetable oil
• 1 tablespoon ginger, minced
• 2 cloves garlic, minced
• 3 tablespoons soy sauce
• 3 tablespoons rice vinegar (more to taste)
• 2 teaspoons white pepper (more to taste)
• 1 teaspoon sesame oil
• 1/4 cup cornstarch mixed with 1/4 cup cold water
• 2 eggs, lightly beaten
• 3 green onions, thinly sliced
• 1 teaspoon white sugar
• 1/2 teaspoon salt (to taste)
• 1 tablespoon chili oil (optional)

Instructions:

1. Soak dried mushrooms and lily flowers (if using) in warm water for 30 minutes until softened
2. Heat vegetable oil in a large pot over medium heat
3. Add ginger and garlic, sautéing until fragrant, about 30 seconds
4. Pour in chicken stock and bring to a simmer
5. Add shiitake mushrooms, wood ear mushrooms, bamboo shoots, and lily flowers
6. Simmer for 10 minutes to infuse flavors
7. Add tofu, soy sauce, rice vinegar, white pepper, sugar, and salt
8. Simmer for another 5 minutes
9. Stir the cornstarch mixture to recombine, then slowly pour into soup while stirring
10. Cook until soup thickens slightly, about 2 minutes
11. Slowly pour beaten eggs into soup in a thin stream while stirring gently to create ribbons
12. Remove from heat and stir in sesame oil and chili oil if using
13. Taste and adjust seasonings – adding more vinegar for sourness or white pepper for heat
14. Garnish with green onions and serve hot

Note: The balance of hot (white pepper) and sour (vinegar) is personal – adjust to your preference. For a more authentic version, seek out Chinese black vinegar instead of rice vinegar. This soup actually improves with time, making it perfect for batch cooking. Store in the refrigerator for up to 4 days, adding a splash of fresh vinegar when reheating to brighten the flavors.
