Why it works: Mushroom and white wine match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and 1,704 recipes mention both. Both carry ethyl octanoate, which smells fruity. The science ↓
The recipe
Ingredients
Contains: egg, milk, wheat (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare the eels
Skin and clean the eels, then soak them in vinegar and boiling water to disgorge.
Dry the eels thoroughly and cut them into equal lengths of 3 to 4 inches.
Make the stew
Combine the eels, mushrooms, and butter in a stewpan and begin to fry.
Dredge the mixture in flour.
Stir in the broth and white wine until it boils.
Season with pepper, salt, herbs, and the minced onion.
Let it stew until the eels are tender.
Skim off any floating grease.
Remove from heat.
Finish and serve
Mix lemon juice with the egg yolks, then stir quickly into the stew to prevent curdling.
Serve 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
- Provide the main protein, which becomes tender and flaky during slow stewing.
- Butter
- Adds richness and carries flavour while the eels and mushrooms begin to fry.
- Flour
- Coats the eels and thickens the stew liquid into a smooth sauce.
- Egg yolks
- Enrich and thicken the finished sauce, giving it a silky body.
- White wine
- Adds acidity and aroma that balance the richness of the butter and yolks.
- Button mushrooms
- Contribute earthy flavour and moisture to the stew.
The step that matters
Stirring the egg yolk and lemon mixture into the stew. Egg yolks thicken when heated, but if the stew is too hot or the yolks are added without being stirred quickly, they can scramble and curdle. Tempering the yolks with lemon juice and stirring fast keeps the sauce smooth.

Fit is the average pairing score against mushroom, butter, flour, white wine, pepper, egg, lemon. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
