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
Boil the beef gravy in a stewpan.
Wash the eels and cut them into 2-inch pieces.
Stew and thicken
Add the eels to the boiling gravy and let them simmer gently for 30 minutes.
Carefully remove the eels with a fish slice and set aside.
Mix the flour, pepper, salt, port wine, mushroom catsup, lemon juice, and water until smooth.
Strain this mixture into the gravy, stirring until it boils.
Let it boil for 10 minutes, then return the eels to heat through.
Serve
Serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Silver eels
- Provide the main protein, which becomes tender as they simmer gently in the gravy.
- Beef gravy
- Forms the savoury liquid base that the eels cook in and the sauce is built on.
- Flour
- Thickens the mixture into a smooth sauce that coats the eels.
- Port wine
- Adds depth, sweetness and acidity to the sauce.
The step that matters
Strain the flour mixture into the gravy and boil. The flour must be fully smooth before it goes in, and the sauce must boil so the starch swells and thickens; lumps or a weak boil leave the sauce thin or grainy.

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