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 the tender seafood body of the soup.
Milk
Forms the creamy liquid base that gives the soup its smooth, rich body.
Butter
Adds richness and carries flavor, and cooks with flour to form a roux.
Flour
Thickens the liquor as its starch swells when cooked in hot liquid.

The step that matters

Cooking the butter and flour together. Flour must be cooked with the butter before it goes into the liquor. Heating the starch in hot liquid makes it swell and thicken smoothly, and cooking it first removes the raw, pasty taste and helps prevent lumps.

Swap the mace

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

  1. Capersfits better
  2. Thymefits better
  3. Tarragonfits better
  4. Macethe original

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