Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled egg yolks
- Mashed into the stock, they thicken the soup and give it a rich, smooth body.
- Oysters
- Provide the main seafood flavour and tender texture in the finished soup.
- Fish stock
- Forms the liquid base that carries the flavour of the whole soup.
- Raw egg yolks
- Thicken the soup when gently heated, giving a smooth, creamy texture.
The step that matters
Stir the raw egg yolks over low heat without boiling. Raw egg yolks thicken through gentle heat as their proteins set. If the soup boils, the yolks can curdle and turn grainy, so it must stay below a simmer.
