Oyster Soup

Ingredients

Directions

The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Make the broth

  1. In a pot, combine water, onion, carrot, celery, bay leaf, salt, and pepper. Bring to a boil.

  2. Add oysters and cook until they curl, about 5 minutes.

Make the cream base and finish

  1. In a separate pan, melt butter and stir in flour to make a roux.

  2. Gradually add cream to the roux, stirring until smooth.

  3. Combine the roux with the oyster mixture and heat through 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.
Cream
Adds richness and a smooth, silky body to the soup.
Flour
Thickens the butter and cream mixture into a smooth roux.
Butter
Carries fat for the roux and adds a rich, savory flavor.
Onion
Adds sweetness and aromatic depth to the broth.

The step that matters

Cook the oysters only until they curl. Oysters are delicate, and prolonged heat toughens their proteins and makes them rubbery and shrunken, so they should be cooked just until the edges curl.

  3. Leekbetter flavor fit
  4. Onionthe original

Fit is the average pairing score against oyster, carrot, celery, pepper, cream, butter, flour. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
