Oyster Bisque

Ingredients

Directions

Prepare the oysters

  1. Remove gills from oysters by dropping them into a hot frying pan and turning until plumped and ruffled on both sides.

  2. Skim out the oysters and add the liquor to a pot with cream, bay leaf, mace, cayenne, paprika, salt, and lemon juice.

Make the bisque

  1. Skim the liquor thoroughly when it boils, then return the oysters chopped finely.

  2. As soon as it boils again, add the flour moistened with cold milk and stir constantly for five minutes.

  3. Add the butter and serve immediately when it melts.

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 the body of the bisque once chopped and returned to the liquid.
Cream
Adds richness and a smooth, silky texture to the soup.
Flour
Thickens the liquid as it boils and is stirred, giving the bisque body.
Butter
Adds fat for richness and a rounded, glossy finish when stirred in at the end.
Lemon juice
Adds acidity that brightens the flavour and balances the cream.

The step that matters

Adding the flour mixture. Flour thickens only when it boils, and stirring keeps it from clumping. Adding it lumpy or to a liquid that is not boiling leaves a grainy texture that does not thicken evenly.

Swap the mace

How well each one fits the dish's main ingredients (oyster, cream, pepper, lemon, flour, milk, butter):

  1. Nutmegfits better
  2. Parsleyfits better
  3. Tarragonfits better
  4. Macethe original

Fit is the average pairing score against oyster, cream, pepper, lemon, flour, milk, butter. Candidates are from the same food group and used in at least 100 recipes.
