Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Eels to Fricassee
Ingredients
Directions
Prepare the eels
Skin and notch the eels from end to end, then cut them into 4 or 5 pieces.
Soak the pieces in spring water for 30 minutes, then dry them with a cloth.
Make the fricassee
In a pan, melt fresh butter and add the eels, onions, and chopped parsley.
Shake the pan over heat for a few minutes, then add white wine and stock, along with pepper, salt, and mace.
Stew for about 30 minutes, then stir in egg yolks, nutmeg, and parsley.
Let it simmer for 4 to 5 minutes, then squeeze in the juice of the Seville orange.

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 after stewing.
- Egg yolks
- Thicken the sauce into a creamy, rich liaison as they gently cook.
- Butter
- Adds richness and carries flavour when the eels are first cooked.
- White wine
- Adds acidity and aroma that balance the richness of the sauce.
- Stock
- Forms the savoury liquid in which the eels stew.
- Seville orange juice
- Adds bright acidity that cuts through the richness of the egg and butter.
The step that matters
Stirring in the egg yolks. Egg yolks thicken through gentle heat; if the sauce boils after they go in, they can scramble and turn grainy. Keep the heat low and the liquid just below a simmer while stirring.
Swap the mace
How well each one fits the dish's main ingredients (butter, onion, parsley, white wine, pepper, egg, nutmeg):
- Thymefits better
- Tarragonfits better
- Marjoramfits better
- Macethe original
Fit is the average pairing score against butter, onion, parsley, white wine, pepper, egg, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
