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 texture of the soup, with their liquor adding brininess.
Butter
Carries the flour to form a roux that thickens the soup and adds richness.
Flour
Thickens the soup when cooked in butter and combined with the liquid.
Milk
Adds body and creamy softness to the soup.
Stock
Forms the savoury liquid base of the soup.

The step that matters

Adding the flour to the butter. Cooking the flour in melted butter before adding liquid forms a roux. Stirring it smooth and letting it cool before adding liquid helps prevent lumps, so the soup thickens evenly.

Flavor stand-ins for the mace

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

  1. Nutmegbetter flavor fit
  2. Capersbetter flavor fit
  3. Parsleybetter flavor fit
  4. Macethe original

Fit is the average pairing score against oyster, butter, flour, milk, pepper, sauce, cream. 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).
