Awesome Mandarin Hot & Sour Soup

Mandarin hot and sour soup is the Beijing-style classic that built the reputation of countless Chinese-American restaurants. The signature flavor comes from a balance of vinegar (sour) and white pepper plus chili oil (hot), with no chili paste in sight. The peppery heat is delicate, almost mustard-like, rather than fiery.

Dried black mushrooms (shiitakes) and wood ear mushrooms are non-negotiable here. They’re what give the soup its earthy, mineral depth and signature dark color. Wood ears in particular have a gentle crunch even after cooking, providing the textural punctuation that defines authentic hot and sour.

The order of additions is precise. Pork shreds and dried mushrooms simmer first to build flavor, the rest of the ingredients go in second, the cornstarch slurry thickens the broth, and finally the beaten eggs drizzle in last for those silky golden ribbons.

Stirring while drizzling the eggs is what creates the thin, delicate strands. A still pot gives you scrambled-egg lumps; a constant gentle stir creates the ribbons.

Chef Tips

• Soak dried mushrooms 30 minutes in hot water, then slice. Save the soaking liquid (strain through cheesecloth) and add to the broth for deeper flavor.
• White pepper is non-negotiable. Black pepper changes the profile and adds visual flecks.
• Add the eggs after the heat is off. Boiling eggs in soup makes them tough and stringy.
• Serve immediately. The texture is best in the first few minutes after the eggs are added.

Variations

• Add cooked chicken or fresh shrimp in place of pork for variation.
• Stir in cubed silken tofu instead of bean curd squares for a softer mouthfeel.
• Finish with a generous drizzle of toasted sesame oil at the table for extra aroma.
