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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eels
- Form the main body of the dish once cooked until tender.
- Butter
- Adds richness and a smooth, rounded mouthfeel to the sauce.
- Wheat flour or rolled cracker
- Thickens the cooking liquid so it clings to the eel pieces.
- Vinegar
- Adds a sharp acidity that brightens the rich, fatty flavour.
The step that matters
Let the mixture simmer for 10 minutes. Simmering gently lets the flour or cracker fully hydrate and thicken the liquid without scorching or breaking the butter, so the sauce turns smooth rather than pasty or greasy.
Swap the parsley
How well each one fits the dish's main ingredients (butter, wheat, pepper, vinegar):
- Parsleythe original
- Tarragonfits about as well
- Cinnamonfits about as well
- Thymefits about as well
Fit is the average pairing score against butter, wheat, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
