Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish stock
- Forms the liquid base of the soup and carries the flavor of the other ingredients.
- Hard-boiled eggs
- Pounded yolks add richness and body to the broth.
- Oysters
- Provide the briny, savory flavor that defines the soup.
- Raw egg yolks
- Thicken the soup as their proteins set gently, giving a smooth, creamy texture.
The step that matters
Stir in the beaten raw egg yolks without boiling. Egg yolk proteins set at moderate heat and thicken the soup. If the soup boils, the yolks curdle and turn grainy instead of smooth, so keep the heat low and stir constantly while they are added.
