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
- Liquor from boiled calf's head
- Forms the savoury body and base flavour of the soup.
- Egg yolks
- Enrich the soup and thicken it gently when heated.
- Milk
- Adds creaminess and softens the broth's richness.
- Corn-starch
- Thickens the soup as it swells in hot liquid.
- Onion
- Adds savoury aroma to the broth.
The step that matters
Adding the boiling milk to the yolks. Hot milk must be combined with the beaten yolks carefully, so the yolks warm gradually and thicken smoothly. Added too quickly or too hot, the egg proteins can scramble into lumps instead of enriching the soup.
Swap the mace
How well each one fits the dish's main ingredients (onion, parsley, milk, egg, pepper, corn):
- Thymefits better
- Dillfits better
- Celeryfits better
- Macethe original
Fit is the average pairing score against onion, parsley, milk, egg, pepper, corn. Candidates are from the same food group and used in at least 100 recipes.
