Oyster Soup
Ingredients
Directions
Prepare the oysters
Place oysters in a small saucepan with their liquor and bring to almost boiling, then strain.
Remove the gills from the oysters, cut them in half, and set aside for later.
Simmer the gills in the liquor and stock for 30 minutes to extract flavor.
Strain the mixture through a fine sieve and rinse the saucepan.
Make the soup
Melt the butter in the saucepan without browning it, then add the flour and mix until smooth.
Pour in the stock and stir constantly over heat until boiling, skimming if necessary.
Season with white pepper, salt, anchovy essence, and cayenne pepper.
In a bowl, beat the egg yolk with the cream and strain into the soup, stirring constantly off the heat.
Serve
Place the oysters in a soup tureen and pour the soup over them before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- Provide the main flavor and tender texture of the soup.
- Butter
- Adds richness and carries flavor, and must not brown to keep the soup pale.
- Flour
- Mixed with butter to form a roux that thickens the soup.
- Egg yolk
- Enriches and thickens the soup when stirred in off the heat.
- Cream
- Adds richness and smoothness, softening the soup's body.
The step that matters
Adding the egg yolk and cream. Egg yolk sets when heated, so the mixture must be stirred constantly and added off the heat; otherwise it can curdle or turn grainy instead of creamy.
