Ingredients You'll Need (and Why)

Dried Shiitake or Wood Ear Mushrooms: Rehydrating dried mushrooms releases a deeply concentrated, savory mushroom essence into the soaking liquid and the soup that fresh mushrooms alone cannot match.

Chinkiang Black Vinegar: This aged Chinese black vinegar provides a malty, woody, and complex acidity that defines the signature sour note of the dish. Avoid substituting standard white vinegar, which is far too sharp.

Ground White Pepper: White pepper delivers a sharper, more immediate heat than black pepper, creating the signature 'hot' element that hits the back of the throat.

Cornstarch Slurry: Mixing cornstarch with cold water before adding it to hot liquid prevents lumps and gives the soup its classic, silky, glossy body.

How to Make It

Rehydrating and Building Flavor

Starting with dried mushrooms gives this soup its foundational depth. Soaking them ahead of time softens their chewy texture while creating a rich baseline. Simmering them alongside fresh mushrooms, ginger, and green onion whites infuses the stock with an aromatic base before any heavy seasonings go in.

Achieving Texture and Balance

The secret to a great hot and sour soup lies in its texture and timing. The cornstarch slurry gives the broth its signature glossy, velvety mouthfeel, which helps suspend the delicate egg ribbons. Stirring the Chinkiang black vinegar in at the very end ensures its bright, complex acidity doesn't cook away on the stovetop.

Success Tips

• Squeeze as much liquid out of the rehydrated dried mushrooms as possible before slicing them to ensure they absorb the fresh broth flavors.
• Add the white pepper gradually if you are sensitive to spice, starting with 1/2 teaspoon and tasting before adding more.
• When adding the egg, make sure the soup is off the heat or on the lowest setting and stir in one steady direction to form delicate, feathery ribbons rather than large clumps.

Storage & Make-Ahead

Fridge: Store leftover soup in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop.

FAQ

Can I use regular white vinegar if I don't have Chinkiang black vinegar?

Chinkiang black vinegar provides a rich, malty flavor that is essential for authentic hot and sour soup. If you are in a pinch, unseasoned rice vinegar or apple cider vinegar can work, though the flavor profile will be lighter and sharper.

Why do I add the vinegar at the end of cooking?

Adding the vinegar right before serving preserves its bright, sharp acidity. If boiled for too long, the volatile aromatic compounds in the vinegar will evaporate, dulling the sour punch.

Can I make this soup vegan?

Yes! Simply use a rich vegetable stock and skip the optional egg step to keep the entire soup strictly vegetarian and vegan-friendly.
