Boiled Eels

Ingredients

Directions

Prepare the poaching liquid

  1. In a pot, combine cold water, lemon slices, mace, white peppercorns, coarse sea salt, and chopped parsley. Bring to a gentle boil and simmer for 20 minutes.

  2. Allow the mixture to cool completely.

Poach the eels

  1. Add the skinned and cleaned eels, cut into 3‑4 inch lengths. Simmer gently for 10‑15 minutes.

  2. Using a slotted spoon, transfer the eels to a hot serving dish.

Make the sauce and serve

  1. In the same pot, mix flour with butter and clotted cream. Bring to a boil, then stir in lemon juice.

  2. Pour the sauce over the eels and serve immediately.

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

What each ingredient does

Eels
The main protein, whose firm, mild flesh is cooked gently in the poaching liquid.
Clotted cream
Adds richness and a smooth, full body to the sauce.
Butter
Adds fat for richness and helps carry flavour in the sauce.
Flour
Thickens the sauce as its starch swells when heated with the fat and liquid.
Lemon juice
Adds acidity that brightens the sauce and cuts through the richness of the cream and butter.

The step that matters

Simmer the eels gently. A hard boil makes the proteins in eel flesh tighten and toughen, and it can break the pieces apart. Keeping the liquid at a gentle simmer cooks the eels through while they stay tender and hold their shape.

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.
