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

What each ingredient does

Eels
Provide the main flesh and body that gives the sauce its rich, savory character.
Flour
Thickens the sauce so it coats the back of a spoon.
Butter
Adds fat and smoothness to the thickened sauce.
Anchovies
Contribute salty, savory depth that builds the sauce's flavor.

The step that matters

Let it simmer until rich. Simmering gently extracts flavor and gelatin from the eels and bones slowly; a hard boil can cloud the liquid and make it greasy or bitter. Stop when the liquid tastes concentrated before thickening.

Swap the mace

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

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

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