Ingredients
  

For the Soup Base
  • 6 cups chicken broth low sodium preferred
  • 6 oz pork tenderloin sliced into thin matchsticks
  • 4 oz firm tofu drained and cubed
  • 1/4 cup dried wood ear mushrooms or substitute shiitake
  • 1/2 cup bamboo shoots sliced
  • 1 tablespoon fresh ginger minced
  • 2 cloves garlic minced
For the Flavor
  • 3 tablespoons coconut aminos or gluten-free tamari
  • 3 tablespoons rice vinegar
  • 1 tablespoon sesame oil
  • 1 teaspoon white pepper this provides the 'hot'
  • 1 teaspoon chili oil optional, for extra heat
For the Finish
  • 2 large eggs beaten
  • 1/4 teaspoon xanthan gum
  • 2 green onions sliced, for garnish

Equipment

  • 1 Large pot or Dutch oven
  • 1 Small bowl 
  • 1 Whisk or chopsticks

Method
 

  1. If using dried wood ear mushrooms, place them in a bowl and cover with hot water. Let sit for 20-30 minutes until softened and expanded. Drain, rinse well, and slice into strips.
  2. Bring the chicken broth to a simmer in a large pot over medium-high heat. Add the ginger and garlic and cook for about 1 minute until fragrant.
  3. Add the sliced pork, tofu cubes, drained wood ear mushrooms, and bamboo shoots. Simmer for 5-6 minutes until the pork is cooked through.
  4. Stir in the coconut aminos, sesame oil, and white pepper. Taste and adjust the pepper level to your preference.
  5. In a small bowl, whisk the xanthan gum with 2 tablespoons of cold water until smooth. Stir this mixture into the soup and simmer for 1 minute. The soup will thicken slightly.
  6. Remove the pot from heat. Stir the soup in a circular motion with one hand while slowly drizzling the beaten eggs in a thin stream with the other. The eggs will cook into silky ribbons.
  7. Stir in the rice vinegar. Taste and adjust the sour/hot balance as desired. Ladle into bowls and garnish with sliced green onions and chili oil if using.

Notes

The Egg Ribbon Technique: The key is to remove the pot from heat before adding the eggs. Drizzle slowly in a very thin stream while stirring—this creates those signature silky wisps instead of scrambled egg chunks.
White Pepper vs Black: Don't substitute black pepper—white pepper has a distinctive earthy heat that defines authentic hot and sour soup.
Make Ahead: Prepare the broth base up to 3 days ahead. Add the eggs and vinegar fresh when reheating for best results.
Vegetarian Option: Use vegetable broth, skip the pork, and double the tofu.
