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
- Chicken
- Provides the main protein body and bulk of the filling.
- Egg yolk
- Binds the pounded mixture together and helps it set when cooked.
- Parmesan
- Adds savory depth and salty flavour to the filling.
- Double cream
- Adds moisture and richness so the filling stays soft and smooth.
The step that matters
Rub the mixture through a fine sieve. Pounding leaves fibres and lumps that make the filling coarse. Pushing it through a fine sieve breaks these down, giving a smooth texture that spreads evenly and does not tear the pasta.
Swap the parsley
How well each one fits the dish's main ingredients (chicken, ham, egg, spinach, cream, nutmeg, pepper):
- Parsleythe original
- Tarragonfits about as well
- Marjoramfits about as well
- Celeryfits about as well
Fit is the average pairing score against chicken, ham, egg, spinach, cream, nutmeg, pepper. Candidates are from the same food group and used in at least 100 recipes.
