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 flavor of the soup as they cook into the liquid.
Butter
Adds richness and carries flavor when the eel pieces are fried.

The step that matters

Fry the pieces lightly. Frying gently softens the eel and builds flavor without deep browning. Over-browning the butter and fish can make the soup taste bitter and darken its color.

Swap the parsley

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

  1. Nutmegfits about as well
  2. Parsleythe original
  3. Capersfits about as well
  4. Sagefits about as well

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