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

What each ingredient does

Eels
Provide the main protein, which becomes tender and flaky during gentle, slow cooking.
Butter
Adds fat and richness, carrying flavour and keeping the eels moist as they cook.
Onion
Adds aromatic sweetness and savoury depth as it softens into the cooking fat.

The step that matters

Gradually bring the water to a boil, then cook gently. Heating the eels slowly in a covered pan with water around it keeps the heat gentle. Fast, high heat would toughen the flesh and could dry it out before it becomes tender.

Swap the parsley

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

  1. Garlicfits better
  2. Capersfits about as well
  3. Thymefits about as well
  4. Parsleythe original

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