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 ↓
Grekn Pea Soup
Ingredients
Directions
Make the soup
Combine the chicken, water, parsley, onion, pepper, and salt in a large pot.
Add the butter and bring the mixture to a boil.
Once boiling, add the shelled peas and cook until they can be mashed.
Mash and thicken
Remove the peas and mash them.
Strain the mash through a colander back into the soup.
Let the soup boil for a short time, then stir in the flour mixed with a little butter.
Just before serving, stir in the cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shelled peas
- Provide the main body and sweet, vegetal flavor once mashed into the broth.
- Flour
- Thickens the soup as it boils, giving it a smoother, heavier body.
- Cream
- Adds richness and a softer, milder finish to the soup.
- Butter
- Adds fat and rich flavor, and helps blend the flour smoothly.
The step that matters
Stirring in the flour. Flour mixed with a little butter should be stirred in while the soup is boiling, so it thickens evenly. Added to cold liquid or dropped in dry, it clumps and leaves a grainy texture.
Swap the peas
How well each one fits the dish's main ingredients (chicken, parsley, onion, pepper, butter, flour, cream):
- Cashew nutfits better
- Chickpeafits better
- Beansfits better
- Peasthe original
Fit is the average pairing score against chicken, parsley, onion, pepper, butter, flour, cream. Candidates are from the same food group and used in at least 100 recipes.
