Why it works: Pepper and parsley 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 ↓
Chicken Broth
Ingredients
Directions
Make the broth
Heat the chicken stock in a pot until it boils.
Add the soaked rice, chopped onion, salt, and pepper.
Cook steadily for 30 minutes, or until the rice is soft.
Stir in the chopped parsley and cook for an additional 10 minutes.
Make the thickened milk
In another saucepan, heat the milk until scalding.
Mix the butter with the corn starch until smooth, then stir into the hot milk.
Cook for 3 minutes, stirring to prevent lumps.
Finish and serve
Remove from heat and beat in the whipped egg.
Return to heat for 1 minute, stirring vigorously.
Pour the soup into a tureen, stirring continuously to prevent curdling.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chicken stock
- Forms the liquid base and carries the flavour of the whole soup.
- Rice
- Softens and thickens the broth as it cooks, adding body to the soup.
- Milk
- Adds richness and a creamy body to the finished soup.
- Corn starch
- Thickens the milk mixture so the soup becomes smooth and velvety.
- Egg
- Enriches the soup and adds body when gently heated into it.
The step that matters
Beat the whipped egg into the soup off the heat, then reheat gently. Egg proteins set and curdle when they meet high heat directly. Removing the pan from heat before adding the egg, and stirring constantly while reheating, keeps the egg smooth and evenly blended.
Swap the parsley
How well each one fits the dish's main ingredients (chicken, rice, onion, pepper, milk, butter, corn):
- Garlicfits better
- Celeryfits about as well
- Thymefits about as well
- Parsleythe original
Fit is the average pairing score against chicken, rice, onion, pepper, milk, butter, corn. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
