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 of the soup as they break down during stewing.
Bread crust
Soaks up and helps thicken the broth as it stews with the fish.
Toasted bread
Soaks up the strained soup, giving a soft, absorbent base in the tureen.
Boiling cream
Adds richness and body to the soup, thickened with flour when used.

The step that matters

Stewing until the fish separates. Cooking gently under a cover lets the eels break down slowly, releasing gelatin and flavour into the broth. Stopping too early leaves a weak soup, while overcooking can make the broth cloudy and muddy.

Swap the mace

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

  1. Celeryfits better
  2. Parsleyfits better
  3. Marjoramfits better
  4. Macethe original

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