Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish stock
- Forms the liquid base of the soup and carries its flavor.
- Hard-boiled egg yolks
- Beaten into the stock to thicken it and give the soup body.
- Oysters
- Supply the main seafood flavor, added cooked at the end to stay tender.
- Raw egg yolks
- Stirred in off the heat to enrich and thicken the soup without fully cooking.
The step that matters
Stir in the beaten raw egg yolks just before serving. Egg yolks thicken when heated gently but can scramble and turn grainy if they boil. Adding them last, with the soup no longer boiling, keeps the texture smooth and creamy.
