Ingredients
Directions
Prepare the oysters
Scald the oysters in their own liquor, remove gills, and cut them in half.
Place the oysters in a soup tureen.
Make the soup
In a stewpan, boil the gills with the white stock or milk and oyster liquor for 15 minutes.
Strain the liquid and let it sit for a few minutes, then pour it away from the sediment.
Melt the butter in a stewpan, mix in the flour, then add the strained stock and cream.
Season with cayenne, nutmeg, and anchovy, and stir over low heat for 15 minutes.
Serve
Pour the soup over the oysters in the tureen and serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- Provide the main flavour and tender texture of the soup.
- Butter
- Adds richness and fat, and with flour forms the base that thickens the soup.
- Flour
- Thickens the stock with the butter, giving the soup body.
- Cream
- Adds richness and smooth body to the finished soup.
- White stock or milk
- Forms the liquid base of the soup.
The step that matters
Thickening the stock with butter and flour. Flour must be cooked into the melted butter before the liquid is added, so it dissolves smoothly and thickens evenly instead of clumping. Stirring over low heat keeps the soup from scorching or curdling the cream.
