Ingredients
Directions
Make the base
Beat the hard part of the oysters in a mortar with the yolks of 10 hard-boiled eggs.
Simmer the mixture for 30 minutes, then strain the liquid.
Finish the soup
Add the remaining oysters, cleaned of their gills, and simmer for a few minutes.
Stir in the 6 beaten raw egg yolks over moderate heat until thick and smooth, ensuring it does not boil.
Season with salt and pepper to taste.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- Provide the main flavour and body of the soup.
- Hard-boiled egg yolks
- Break down into a smooth base that thickens and enriches the broth.
- Raw egg yolks
- Thicken the soup as they gently set when stirred into the warm liquid.
The step that matters
Stir in the raw egg yolks without boiling. Egg yolks thicken by gentle coagulation. If the soup boils, the yolks can scramble and turn grainy, so the mixture should stay hot but below a boil while stirring until smooth.
