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
Boil the eels in water with vinegar, then drain them.
Make the sauce
In a stewpan, melt butter with flour without burning it.
Add white wine and boiling water to the butter mixture.

Beat the egg yolks with cream and add to the stew, warming gently 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
- Main protein that becomes tender as it stews in the sauce.
- Butter
- Fat that carries flavor and, with flour, forms the base of the sauce.
- Flour
- Thickens the butter into a roux that gives the sauce body.
- Egg yolks
- Thicken the cream enrichment so the sauce turns rich and smooth when warmed gently.
- Cream
- Adds richness and a smooth, silky texture to the sauce.
- Mushrooms
- Add earthy flavor and savory depth to the stew.
The step that matters
Warming the egg yolk and cream mixture. Egg yolks begin to set and can curdle if they get too hot. Warming the stew gently without boiling keeps the sauce smooth and creamy rather than grainy.
Swap the onion
How well each one fits the dish's main ingredients (vinegar, butter, flour, white wine, pepper, mushroom, lemon):
- Shallotfits better
- Capsicumfits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against vinegar, butter, flour, white wine, pepper, mushroom, lemon. Candidates are from the same food group and used in at least 100 recipes.
