Ingredients

Directions

Prepare

  1. Skin and clean the eels, then cut them into short lengths.

  2. Soak the eels in cold water for 30 minutes.

Cook and finish

  1. Place the eels in a pot with just enough cold water to cover them and cook slowly for 30 to 60 minutes, depending on their size.

  2. Drain the water and cover the eels with a good white sauce seasoned with paprika, onion juice, coarse sea salt, and minced parsley.

  3. Simmer for 5 minutes and serve.

The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Sauce and onion barely smell alike, yet cooks put them together in 10,474 recipes: they work on texture and structure more than aroma.

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 through slow, gentle cooking.
White sauce
Adds a creamy, moist coating that carries the seasonings over the eels.
Paprika
Adds mild color and a gentle, peppery aroma to the sauce.
Onion juice
Adds savory, aromatic flavor to the white sauce.

The step that matters

Cooking the eels slowly in just enough water. Eel flesh turns firm and tough if it boils hard or cooks too fast. Gentle simmering with only enough water to cover keeps it tender and concentrates its flavor, and the cooking time should follow the size of the pieces.

Swap the parsley

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

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

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