📝 About This Recipe

A cornerstone of Northern Chinese cuisine, this Hot and Sour soup is a masterclass in balancing bold, contrasting flavors. The 'hot' comes from a generous pinch of white pepper, while the 'sour' is derived from aged black vinegar, creating a complex broth that is both invigorating and comforting. Naturally dairy-free and packed with umami-rich mushrooms and silky tofu, this recipe delivers a restaurant-quality experience right in your home kitchen.

🥗 Ingredients

The Broth Base

  • 6 cups Chicken or Vegetable Stock (high quality, low sodium)
  • 6 pieces Dried Shiitake Mushrooms (rehydrated in warm water, then thinly sliced)
  • 1/4 cup Wood Ear Mushrooms (dried, rehydrated and thinly sliced)
  • 1/2 cup Bamboo Shoots (canned, sliced into matchsticks)
  • 1 tablespoon Fresh Ginger (grated or finely minced)

Proteins

  • 8 ounces Firm Tofu (cut into 1/4 inch thick matchsticks)
  • 2 large Eggs (well beaten)

The Flavor Seasoning

  • 4 tablespoons Chinkiang Black Vinegar (or balsamic vinegar as a substitute)
  • 2 tablespoons Light Soy Sauce (for saltiness)
  • 1 teaspoon Dark Soy Sauce (primarily for a rich amber color)
  • 1.5 teaspoons Ground White Pepper (adjust to preferred heat level)
  • 1 teaspoon Toasted Sesame Oil (added at the end for aroma)

Thickener and Garnish

  • 3 tablespoons Cornstarch (mixed with 3 tbsp water to make a slurry)
  • 2 stalks Green Onions (finely chopped)
  • 1 handful Fresh Cilantro (roughly chopped for garnish)
  • 1 teaspoon Chili Oil (optional, for extra heat)

👨‍🍳 Instructions

  1. 1

    Begin by rehydrating the dried shiitake and wood ear mushrooms in a bowl of warm water for about 20 minutes. Once soft, squeeze out excess water, remove any woody stems, and slice them into thin strips.

  2. 2

    In a large pot or wok, bring the 6 cups of stock to a gentle boil over medium-high heat.

  3. 3

    Add the sliced shiitake mushrooms, wood ear mushrooms, bamboo shoots, and minced ginger to the boiling stock. Reduce heat to medium and simmer for 5 minutes to infuse the broth.

  4. 4

    Gently slide the tofu matchsticks into the pot, taking care not to break them. Let the soup return to a simmer.

  5. 5

    In a small bowl, whisk together the light soy sauce, dark soy sauce, and white pepper. Pour this mixture into the soup and stir gently.

  6. 6

    Taste the broth. Add the Chinkiang black vinegar. It is important to add the vinegar toward the end to maintain its bright, sharp profile.

  7. 7

    Give your cornstarch slurry a quick stir to ensure it's smooth, then slowly drizzle it into the simmering soup while stirring constantly. The soup should thicken to a glossy, coat-the-back-of-a-spoon consistency.

  8. 8

    Turn the heat down to low. To create the 'egg ribbons,' hold a pair of chopsticks or a fork over the pot and slowly pour the beaten eggs through them in a steady stream while moving in a circular motion.

  9. 9

    Wait 10 seconds before stirring very gently; this allows the egg to set into beautiful, thin wisps rather than clouding the broth.

  10. 10

    Remove the pot from the heat. Stir in the toasted sesame oil and the white parts of the green onions.

  11. 11

    Ladle the hot soup into bowls and garnish generously with the green onion tops, cilantro, and a drizzle of chili oil if you desire more heat.

💡 Chef's Tips

Use white pepper instead of black pepper for the traditional 'floral' heat that characterizes this dish. Don't skip the wood ear mushrooms; they provide a unique, crunchy texture that defines authentic hot and sour soup. If the soup isn't sour enough for your liking, add vinegar one teaspoon at a time at the very end. Ensure the soup is simmering, not at a rolling boil, when adding the egg to get the perfect silky ribbons. For a vegan version, simply omit the egg and use vegetable stock.

🍽️ Serving Suggestions

Serve alongside crispy vegetable spring rolls for a texture contrast. Pairs beautifully with a side of steamed Jasmine rice or scallion pancakes. Enjoy with a chilled glass of Riesling or a pot of Jasmine tea to balance the spice. Add a side of smashed cucumber salad with garlic for a refreshing palate cleanser.
