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
- Green peas
- Provide the main body and flavor, thickening the soup when pounded and sieved.
- Stock
- Forms the liquid base that carries flavor and extracts color from the other ingredients.
- Onions
- Build a savory, aromatic base that deepens in flavor as they stew.
- Bacon
- Adds fat and smoky, savory flavor when fried with the parsley.
The step that matters
Pass the soup through a fine sieve. Pounded peas leave fibrous bits that make the soup grainy unless they are pressed through a fine sieve, which gives the smooth, creamy texture the soup should have.
Swap the peas
How well each one fits the dish's main ingredients (onion, veal, parsley, sugar, pepper):
- Chestnutfits better
- Beansfits better
- Chickpeafits better
- Peasthe original
Fit is the average pairing score against onion, veal, parsley, sugar, pepper. Candidates are from the same food group and used in at least 100 recipes.
