A classic Chinese restaurant staple made right in your own kitchen. This hearty soup features a perfect balance of spicy white pepper and tangy vinegar, filled with a variety of textures from mushrooms, bamboo shoots, and tender tofu.
Rehydrate the dried ingredients by placing the lily flowers, wood ear mushrooms, and shiitake mushrooms in separate bowls. Cover each with 1 cup of hot water and soak for approximately 1 hour until fully hydrated. Strain and reserve the shiitake soaking liquid to add depth to your broth.
Prepare the vegetables and tofu: Trim the tough, woody ends off the lily flowers and cut them in half. Roughly chop the wood ears and thinly slice the shiitake mushrooms. Slice both the spiced tofu and the fresh firm tofu into thin strips about 2 inches long.
In a large soup pot, combine the vegetable stock with the strained mushroom soaking water and bring to a boil. Stir in the salt, sugar, dried chili peppers, white pepper, dark soy sauce, light soy sauce, and sesame oil to create the flavorful base.
Add the prepared lily flowers, wood ears, shiitake mushrooms, and bamboo shoots to the pot. Bring the mixture back to a simmer, then gently stir in the spiced tofu, firm tofu, and white vinegar.
In a small bowl, whisk the cornstarch with 1/4 cup of cold water to create a smooth slurry. Ensure there are no lumps, as cornstarch tends to settle at the bottom.
While the soup is simmering, use a ladle to stir the liquid in a steady circular motion to create a whirlpool. Slowly drizzle in the cornstarch slurry to prevent clumping. Continue to simmer for about 30-60 seconds until the soup has thickened.
Taste the broth and adjust the seasonings to your liking. You can add more white pepper for heat, more vinegar for tang, or a splash more soy sauce for saltiness.
With the soup at a light simmer, stir in a circular motion once more. Slowly pour the beaten egg into the soup in a very thin stream to create delicate egg ribbons. Once the egg is cooked, stir in the chopped scallions and serve hot.
For a vegan version, simply omit the egg. To achieve the best texture, try to slice all your ingredients into uniform matchsticks. If you prefer a darker, richer color, you can add an extra teaspoon of dark soy sauce.
