Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Chicken broth
Provides the savory liquid base that carries all the other flavors.
Cornstarch
Thickens the broth into the silky body typical of hot and sour soup.
Egg
Sets into soft ribbons when poured into hot soup, adding richness and texture.
Tofu
Adds soft body and absorbs the surrounding soup flavors.
White vinegar
Adds the sour note that defines the dish.
Soy sauce
Adds salty, savory depth to the broth.

The step that matters

Pouring the beaten egg. Pouring the egg in a slow, fine stream into barely moving hot soup lets it cook into thin ribbons. Dumping it in or stirring too early leaves scattered clumps instead of silky strands.
