Ingredients
Directions
Prepare the base
Remove gills from the oysters and boil the gills in fish stock for a few minutes.
Pound half the oysters with the hard-boiled egg yolks, butter, salt, white pepper, and lemon juice.
Strain the stock.
Make the soup
Stir in the pounded mixture along with the oyster liquor.
Simmer for 30 minutes.
Adjust seasoning with more salt, pepper, and cayenne.
Add the remaining oysters and beaten raw egg yolks.
Do not let the soup boil after adding the oysters and raw eggs.
Stir gently until thick and smooth.
Serve
Serve very hot in a tureen.

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 a tender, briny texture in the soup.
- Hard-boiled egg yolks
- Enrich the soup and give it a smooth, body-building texture when pounded.
- Raw egg yolks
- Thicken the soup as they set gently with heat, giving a smooth, rich body.
- Fresh butter
- Adds fat for richness and a silky mouthfeel.
- Fish stock
- Forms the liquid base that carries the soup's savoury flavour.
The step that matters
Do not let the soup boil after adding the oysters and raw eggs. Raw egg yolks can curdle or turn grainy when boiled, and oysters toughen quickly with high heat. Keeping the soup just below boiling while stirring gently keeps it thick, smooth, and tender.

Fit is the average pairing score against oyster, fish, egg, butter, lemon. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
