Add this mixture to the fish stock and let it simmer for 30 to 35 minutes.

Beat the yolks of the fresh eggs and add to the soup, stirring continuously until thick and smooth.
Keep the soup hot, but do not let it boil, then serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fresh egg yolks
- Thicken the soup and make it smooth and rich when stirred in gently.
- Oysters
- Provide the main briny seafood flavor and tender texture in the soup.
- Fish stock
- Forms the liquid base that carries the flavor of the soup.
- Hard-boiled eggs
- Their yolks are mashed into the stock, adding body and richness to the broth.
The step that matters
Adding the fresh egg yolks. Egg proteins thicken when heated gently but curdle if they get too hot or are added to boiling liquid. Stirring constantly while adding the yolks and keeping the soup below a boil gives a smooth, thick result.
