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

What each ingredient does

Eels
Provide the main body of the dish, cooked gently in the poaching liquid until tender.
Clotted cream
Adds richness and body to the sauce, giving it a smooth, thick texture.
Butter
Adds fat and flavour to the sauce and helps the flour blend smoothly.
Flour
Thickens the butter and cream sauce so it coats the eels.
Lemon juice
Adds acidity that brightens the rich cream sauce.

The step that matters

Simmer the eels softly. A gentle simmer cooks the eels through while keeping their flesh tender. A hard boil toughens and breaks up the delicate fish.

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.
