What each ingredient does
- Fish stock
- Forms the liquid base and carries the soup's main savory flavor.
- Hard-boiled egg yolks
- Mashed into the broth to thicken it and give it a rich, smooth body.
- Oysters
- Supply the characteristic briny, seafood flavor and tender texture of the soup.
- Raw egg yolks
- Enrich and thicken the soup, adding silkiness and a creamy mouthfeel.
The step that matters
Stirring the raw egg yolks into the soup. Raw egg yolks thicken by gentle heat. If the soup boils after they are added, the proteins set and curdle, leaving grainy specks instead of a smooth, velvety broth. Stir them in gradually and keep the heat low.
