Why it works: Pepper and parsley 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
- Eel
- Forms the main body of the dish, rolled and set around its seasoning.
- Vinegar
- Adds acidity to the pickle, giving the cooked eel a sharp, tangy flavour.
- Cloves
- Contribute a warm, aromatic spice flavour to the seasoning rubbed inside the eel.
- Mace
- Adds a warm, aromatic flavour to the seasoning rubbed inside the eel.
The step that matters
Rolling and binding the eel tightly. A tight roll with coarse tape holds the eel's shape while it cooks, so the slices hold together when served. Loose rolling lets the eel fall apart during boiling and cooling.
Swap the mace
How well each one fits the dish's main ingredients (pepper, clove, vinegar, parsley):
- Allspicefits better
- Tarragonfits better
- Marjoramfits better
- Macethe original
Fit is the average pairing score against pepper, clove, vinegar, parsley. Candidates are from the same food group and used in at least 100 recipes.
