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 ↓
Eels a LA Poulette
Ingredients
Directions
Prepare the eels
Skin and clean the eels, then cut them into pieces.
Boil the eels in water with vinegar, then drain them.
Make the sauce
In a stewpan, melt butter mixed with flour without burning it.
Moisten the mixture with wine and boiling water.
Add salt, pepper, sweet herbs, mushrooms, lemon juice, and onion.
Let the eels stew in this mixture for half an hour.
Finish and serve
Beat the egg yolks with cream and add to the stew, warming without boiling.
Serve the dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eels
- Form the main body of the dish, becoming tender as they stew in the sauce.
- Butter
- Carries flavour and enriches the sauce, while forming the base for the thickening roux.
- Flour
- Thickens the sauce when cooked with butter, giving it body.
- Egg yolks
- Enrich and thicken the finished sauce when warmed gently with cream.
- Cream
- Adds richness and smoothness, softening the sauce's flavour and texture.
- Mushrooms
- Add earthy flavour and savoury depth to the sauce.
The step that matters
Warming the egg yolk and cream. Egg yolks thicken when heated gently but scramble if they boil. Keeping the stew below boiling after adding the yolk and cream gives a smooth, lightly thickened sauce rather than a grainy one.
Swap the onion
How well each one fits the dish's main ingredients (vinegar, butter, flour, wine, pepper, mushroom, lemon):
- Shallotfits better
- Capsicumfits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against vinegar, butter, flour, wine, pepper, mushroom, lemon. Candidates are from the same food group and used in at least 100 recipes.
