Make the broth
Simmer the fish stock in a pot.
In a mortar, beat the hard-boiled egg yolks and the hard parts of the oysters.
Add the oyster mixture to the simmering stock and cook for 30 minutes.

Finish and serve

Beat the raw egg yolks and stir them into the soup, mixing well without boiling.
Serve the soup hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- Provide the main flavor and tender meat that finishes the soup.
- Fish stock
- Forms the liquid base that carries the flavor of the whole soup.
- Raw egg yolks
- Thicken the soup and add richness when stirred in off the boil.
- Hard-boiled egg yolks
- Are crushed into the broth to add body and a creamy, rich texture.
The step that matters
Stirring in the raw egg yolks without boiling. Raw yolks thicken through gentle heat; if the soup boils, the yolks can scramble into grainy bits instead of giving a smooth, silky texture.
