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 ↓
Eel, to Fricassee
Ingredients
Directions
Prepare the eels
Skin and notch the eels from end to end.
Cut the eels into 4 or 5 pieces each.
Soak the eel pieces in spring water for 30 minutes.

Make the fricassee
Melt fresh butter in a pan.
Add the eels, onions, and chopped parsley to the pan. Shake the pan over heat for a few minutes.
Add white wine and stock to the pan. Season with pepper, coarse sea salt, and mace. Simmer for about 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eels
- Firm, mild flesh that holds its shape and becomes tender during slow simmering.
- Egg yolks
- Thicken the sauce into a smooth, creamy coating as they gently set with heat.
- White wine
- Adds acidity and aroma and helps build the flavour of the cooking liquid.
- Butter
- Adds richness and fat, carrying flavour from the onions and parsley.
- Seville orange juice
- Brightens the sauce with acidity that balances the richness of the yolks and butter.
The step that matters
Stirring in the egg yolks. Yolks are a thickener that can scramble if the liquid is too hot or they are added too fast. Keep the heat low and stir steadily so the sauce turns silky rather than grainy.
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.
