Ingredients

Directions

Prepare the oysters

  1. In a pot, combine oysters and water.

  2. Heat until it scalds, then strain the liquid and keep warm.

Make the base

  1. In another saucepan, melt butter over medium heat.

  2. When it bubbles, add flour and stir for a few moments without browning.

  3. Gradually add milk, then stir in the oysters, salt, cayenne pepper, and mace.

  4. Bring the mixture to just below boiling, then add the strained oyster liquid.

  5. Taste and adjust seasoning, then 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 flavor and tender, briny body of the soup.
Butter
Carries flavor and enriches the texture of the base.
Flour
Thickens the butter and milk into a smooth, light body.
Rich milk
Forms the creamy liquid that gives the soup its richness.

The step that matters

Adding the milk to the roux. Flour cooked in butter thickens by starch swelling as liquid is added. Adding milk gradually while stirring keeps the mixture smooth instead of lumpy.

Swap the mace

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

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

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