Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Stewed Eels
Ingredients
Directions
Prepare
Wash the eels well and cut them into pieces 2-3 inches long.
Place the eels in a pan with the onion, cloves, sweet herbs, mace, and whole pepper in a muslin rag.
Stew
Add enough water to create a sauce and let them stew softly.
Add the juice of ½ lemon and butter rolled in flour.
When tender, remove the onion, cloves, herbs, mace, and pepper.
Season and serve
Season with coarse sea salt to taste and serve with the sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eels
- Are the main protein; they become tender and flaky as they stew gently in liquid.
- Butter
- Adds richness and fat to the sauce, carrying flavour and giving it a smooth body.
- Flour
- Rolled into the butter, it thickens the cooking liquid into a smooth sauce.
- Lemon juice
- Adds acidity that brightens the flavour of the rich sauce.
The step that matters
Stew softly until tender. Eels need gentle, low heat in liquid to become tender. A hard boil can toughen and break the flesh, so keep the liquid barely simmering.
Swap the mace
How well each one fits the dish's main ingredients (onion, clove, pepper, lemon, butter, flour):
- Thymefits better
- Parsleyfits better
- Cardamomfits better
- Macethe original
Fit is the average pairing score against onion, clove, pepper, lemon, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
