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
- Egg yolks
- Thicken the sauce into a smooth, creamy binding as they gently cook.
- Butter
- Adds richness and a silky mouthfeel to the broth.
- Port wine
- Adds sweetness and depth of flavour to the sauce.
- Vinegar
- Adds acidity that brightens the sauce and balances the richness.
The step that matters
Stir quickly over heat for 1-2 minutes. Egg yolks thicken through gentle heat, but if they get too hot they scramble into curds. Keep the mixture moving and watch it closely so the sauce turns smooth rather than grainy.
Swap the onion
How well each one fits the dish's main ingredients (beef, parsley, butter, pepper, egg, port wine, vinegar):
- Shallotfits better
- Capsicumfits better
- Chivefits about as well
- Onionthe original
Fit is the average pairing score against beef, parsley, butter, pepper, egg, port wine, vinegar. Candidates are from the same food group and used in at least 100 recipes.
