Oyster Soup
Ingredients
Directions
Make the stock base
Beat the yolks of 10 hard‑boiled eggs and the hard part of 2 quarts of oysters in a mortar.
Add this mixture to 2 quarts of fish stock and simmer for 30 minutes.
Strain the soup and return it to the pot with the cleaned oysters.
Simmer for 5 minutes.
Finish and serve
Beat 6 raw egg yolks and add them to the soup, stirring gently until thick and smooth without boiling.
Serve immediately.

What each ingredient does
- Hard-boiled egg yolks
- Mashed into the stock, they add richness and body to the soup.
- Raw egg yolks
- Thicken the soup and make it smooth when stirred in off the boil.
- Oysters
- Provide the main seafood flavour and tender texture in the soup.
The step that matters
Adding the raw egg yolks. Raw yolks thicken by gentle heat; if the soup boils, they can scramble into grainy specks instead of giving a smooth, thick texture.
