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 a LA Poulette
Ingredients
Directions
Prepare
Disgorge the eels in vinegar and boiling water, then dry thoroughly and cut into 3 to 4-inch pieces.
Combine the eels, mushrooms, and butter in a stewpan.
Begin to fry the mixture.
Dredge the mixture in flour.
Make the stew
Add the broth and white wine.
Stir until the liquid boils.
Season with pepper, salt, and minced onion.
Let the stew cook until the eels are tender.
Skim off any floating grease.
Remove the stew from heat.
Finish and serve
Mix the lemon juice with the egg yolks.
Stir the mixture quickly to prevent curdling.
Do not return the mixture to heat.
Serve the eels with croutons and lemon pieces for garnish.

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, becoming tender as they simmer in the stew.
- Button mushrooms
- Add earthy flavour and soft texture to the stew.
- Butter
- Adds fat and richness, and helps the eels and mushrooms brown when fried first.
- Flour
- Coats the pieces and thickens the cooking liquid into a light sauce.
- Egg yolks
- Enrich and thicken the finished sauce, giving it a smooth, creamy body.
- White wine
- Adds acidity and aroma to the broth, balancing the richness.
The step that matters
Adding the egg yolk and lemon mixture off the heat. Egg yolks thicken by gentle heat, but if the liquid gets too hot or is not stirred quickly, the proteins scramble and the sauce curdles. Stirring briskly and keeping the pan off the heat keeps it smooth.
Swap the onion
How well each one fits the dish's main ingredients (butter, white wine, lemon, mushroom, flour, pepper, egg):
- Shallotfits better
- Asparagusfits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against butter, white wine, lemon, mushroom, flour, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
