Boiled Eels

Ingredients

Directions

Prepare the broth

  1. Pare the lemon, removing the white inner rind, slice it, and remove the seeds.

  2. In a pot, combine the lemon, mace, white peppercorns, coarse sea salt, parsley, and cold water.

  3. Bring to a gentle boil and simmer for 20 minutes.

  4. Let the mixture cool, then add the eels cut into 3-4 inch lengths.

  5. Simmer the eels softly for 10-15 minutes.

Make the sauce and serve

  1. Lift the eels into a hot dish.

  2. In the same pot, add minced parsley, flour mixed with butter, and clotted cream, and bring to a boil.

  3. Stir in the lemon juice and pour the sauce over the eels before serving.

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

What each ingredient does

Eels
Form the main body of the dish, cooked gently so the flesh stays tender.
Clotted cream
Adds richness and a thick, smooth body to the sauce.
Flour
Thickens the sauce as it heats with the butter.
Butter
Adds fat and richness, and helps the flour thicken the sauce smoothly.
Lemon juice
Adds acidity that brightens the rich cream sauce.

The step that matters

Simmer the eels softly for 10-15 minutes. At a rolling boil the delicate eel flesh toughens and breaks apart. A gentle simmer cooks the fish through while keeping it moist and tender.

Swap the mace

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

  1. Tarragonfits better
  2. Nutmegfits better
  3. Capersfits better
  4. Macethe original

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