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

What each ingredient does

Eels
Provide the main body and rich flavour of the soup.
Onion
Adds savoury sweetness and aromatic depth to the broth.
Toasted bread
Soaks up the hot broth, giving the soup body and a soft texture.

The step that matters

Boil the eels until broken. Simmering in a covered pan keeps the liquid from evaporating while the eel proteins and collagen soften and release flavour into the broth. Stopping too early leaves the flesh firm and the soup thin; boiling too hard can make the broth cloudy.

Swap the mace

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

  1. Thymefits better
  2. Marjoramfits better
  3. Garlicfits better
  4. Macethe original

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