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

What each ingredient does

Eels
The main protein, which becomes tender through long, gentle cooking.
Butter
Adds fat and richness, giving the gravy a smooth, rounded mouthfeel.
Onion
Adds aroma and savory sweetness as it softens in the cooking liquid.
Parsley
Contributes fresh, herbal aroma that lightens the rich butter and eel flavors.

The step that matters

Bringing the water to a boil slowly. Eel flesh toughens and breaks apart when heated too hard. Gentle, sustained heat in a tightly covered jar lets the connective tissue soften while the meat stays intact.

Swap the onion

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

  1. Carrotfits better
  2. Shallotfits better
  3. Potatofits better
  4. Onionthe original

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