  • 1 pound firm tofu – Cubed to add protein and texture.

Step-by-Step Instructions for Making Hot and Sour Soup

Step 1: Prepare the Woodear Mushrooms

  1. Add the woodear mushrooms to a bowl of boiling water.
  2. Let the mushrooms sit in the water for 30 minutes, which will rehydrate them and make them easier to slice.
  3. After 30 minutes, slice the mushrooms very thinly. Discard any pieces that remain tough or rubbery.

Step 2: Prepare the Chicken Stock Base

  1. In a large Dutch oven or a heavy-bottomed pot, add the green onions, garlic cloves, yellow onion, and black peppercorns to the chicken stock. For easier removal later, you can place these ingredients in a bouquet garni bag.
  2. Bring the mixture to a simmer over medium heat. Allow it to cook for 20 minutes, reducing the liquid by about one-third. This process infuses the stock with deep flavors from the aromatics.
  3. Once the stock has reduced, remove the green onions, garlic, onion, and peppercorns if not using a bouquet garni bag.

Step 3: Sauté the Pork Tenderloin

  1. In a large skillet, heat the vegetable oil over medium-high heat.
  2. Add the sliced pork tenderloin and cook until it’s browned and slightly crispy, which will give the soup a rich, meaty flavor.
  3. Once cooked, remove the pork from the pan and set it aside.

Step 4: Combine Seasonings and Aromatics

  1. To the same skillet, add ginger, bamboo shoots, red chile paste, soy sauce, rice vinegar, white pepper, and sugar.
  2. Stir well to combine all the ingredients, then bring the mixture to a boil.
  3. Once boiling, transfer the contents of the skillet to the pot with the chicken stock.

Step 5: Add Mushrooms, Tofu, and Cornstarch Mixture

  1. Add the prepared mushrooms and cubed tofu to the pot with the seasoned chicken stock.
  2. In a small bowl, mix 2 tablespoons of cornstarch with 1/4 cup water until smooth.
  3. Pour the cornstarch mixture into the soup, stirring gently to incorporate. This will help thicken the soup slightly.
  4. Let the soup cook over medium-low heat for about 10 minutes, allowing the flavors to meld.

Step 6: Create the Egg Ribbons

  1. With the soup on a low simmer, gently stir the soup in a clockwise direction. Pour the beaten eggs slowly into the soup, stirring gently.
  2. As the eggs cook, they will form delicate, silky ribbons throughout the soup. Be careful not to pour the eggs too quickly, as this can cause them to clump together.

Step 7: Garnish and Serve

  1. Once the soup is fully cooked, ladle it into bowls.
  2. Garnish with additional sliced green onions for a pop of color and a hint of fresh flavor.
  3. Serve hot, and enjoy the perfect balance of spicy, sour, and savory flavors.

Tips for Perfect Hot and Sour Soup

1. Choose the Right Mushrooms

Woodear mushrooms are traditional for hot and sour soup, as they bring a unique texture and mild flavor. If you cannot find them, dried shiitake mushrooms are a good substitute.

2. Control the Spice Level

Red chile paste is the main source of heat in this soup. If you prefer a milder flavor, you can reduce the amount or substitute it with a milder chili sauce.

3. Adjust the Thickness

For a thicker soup, increase the amount of cornstarch mixed with water. Alternatively, if you prefer a thinner consistency, omit the cornstarch altogether.

4. Use Low-Sodium Soy Sauce

This allows better control over the saltiness of the soup. You can always add more salt later if needed.

5. Add White Pepper Carefully

White pepper has a distinct, sharp heat that’s unique to hot and sour soup. Start with a small amount, as it can quickly overpower other flavors.

Health Benefits of Hot and Sour Soup

Hot and sour soup offers a variety of health benefits due to its diverse ingredients. The mushrooms and tofu provide protein and fiber, while the ginger and garlic offer immune-boosting properties. With chicken stock as its base, the soup is rich in collagen and other essential nutrients. The vinegar and spices help with digestion, making this soup a flavorful and nourishing choice.

Serving Suggestions

Hot and sour soup is versatile and can be enjoyed on its own or with a side of steamed rice or noodles. It pairs well with other Chinese-inspired dishes, such as spring rolls, dumplings, or stir-fried vegetables, for a complete meal.
