Why it works: Lemon and pepper 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 ↓
Eels, Stewed
Ingredients
Directions
Prepare
Wash and skin the eels, then cut them into 3‑inch pieces.
Season the eels with salt and pepper, and place them in a stewpan.
Stew
Pour the stock over the eels, add the onion stuck with cloves, lemon peel, and wine.
Simmer gently for about 1 hour, then carefully lift the eels onto a hot serving dish.
Make the sauce and serve
Strain the gravy, stir in the cream and enough flour to thicken, and boil for 2 minutes.
Add cayenne and lemon juice, pour the sauce over the eels, and serve hot.

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, becoming tender during gentle simmering.
- Stock
- Supplies the liquid base and savoury depth for the stewing and gravy.
- Port or madeira wine
- Adds acidity and aroma that balance the richness of the gravy.
- Cream
- Adds fat and smoothness, softening the gravy's flavour and texture.
- Flour
- Thickens the strained gravy so it coats the eels.
The step that matters
Simmer gently. Rapid boiling toughens and breaks up delicate eel flesh, so a gentle simmer keeps the pieces tender and intact while they cook through.
Swap the onion
How well each one fits the dish's main ingredients (clove, lemon, madeira wine, cream, flour, pepper):
- Shallotfits better

- Arrowrootfits better
- Onionthe original
Fit is the average pairing score against clove, lemon, madeira wine, cream, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
