Plain Oyster Soup

Ingredients

Directions

Prepare

  1. Strain the oysters.

  2. If the liquor is not perfectly fresh, discard it and use one pint of water instead.

Make the soup

  1. Add a small onion, three blades of mace, some finely chopped celery, pepper, and salt.

  2. Bring the mixture to a boil, then add the oysters.

  3. When the mixture has just come to a boil, add enough cream and milk to fill the tureen.

Thicken

  1. Thicken the soup with flour and butter rubbed together, about two spoonfuls of flour and three ounces of butter to a tureen full, and three pints large oysters.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Oysters
Provide the main body and briny flavor of the soup.
Flour
Thickens the soup as its starch swells when heated in liquid.
Butter
Adds richness and fat, and helps the flour blend smoothly.
Cream and milk (in the method)
Add richness and a creamy, smooth texture to the broth.

The step that matters

Rubbing the flour and butter together. Flour needs to be evenly coated in fat and then heated in the liquid so its starch swells and thickens the soup without lumps. Adding it raw or in clumps leaves pockets of unthickened flour.

Swap the mace

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

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

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