Why it works: Parsley and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eels
- Provide the main flesh, which firms and separates from the bone when gently stewed.
- Flour
- Thickens the strained broth into a binding sauce that holds the fish together.
- Butter
- Enriches the thickened sauce, adding richness and smooth body.
- Lemon
- Adds a bright acidity that lightens the flavour of the rich broth.
The step that matters
Stew gently until the fish separates from the bone. Boiling hard toughens the eel and breaks the flesh apart, while gentle simmering cooks it evenly so it lifts cleanly from the bones.
Swap the mace
How well each one fits the dish's main ingredients (parsley, lemon, flour, butter):
- Thymefits better
- Marjoramfits better
- Capersfits better
- Macethe original
Fit is the average pairing score against parsley, lemon, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
