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 and flaky as they stew slowly.
Flour
Thickens the butter and onion base, giving the sauce body as it cooks.
Butter
Carries the frying of the onion and adds richness and browning to the base.
Port wine
Adds depth and sweetness to the sauce once it is brought to a boil.
Mushroom ketchup
Adds savoury, umami depth to the finished sauce.

The step that matters

Let it stew slowly for about 30 minutes until the fish is cooked. Eel cooks through gently; a hard boil can toughen and break the flesh, so a slow simmer keeps the pieces tender and intact.

Swap the mace

How well each one fits the dish's main ingredients (port wine, mushroom, ketchup, onion, pepper, butter, flour):

  1. Thymefits better
  2. Parsleyfits better
  3. Marjoramfits better
  4. Macethe original

Fit is the average pairing score against port wine, mushroom, ketchup, onion, pepper, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
