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 ↓
Egg Soup
Ingredients
Directions
Prepare the broth
Cool the broth from the boiled chicken feet and giblets.
Skim the broth.
Set the broth over the heat and season with salt and pepper.
Once it boils, remove from heat.

Transfer the mixture to a jar.
Place the jar in boiling water, stirring until it thickens.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set and thicken as they heat, giving the soup a light, body-rich texture.
- Broth
- Provides the liquid and main savoury flavour base for the soup.
- Stale bread
- Soaks up liquid and adds a soft, slightly chewy texture to the soup.
The step that matters
Thickening the eggs in the jar. Eggs set gently at temperatures just below boiling. Overheating or stirring too vigorously can make them curdle or turn grainy, so the mixture should thicken smoothly rather than scramble.
Swap the parsley
How well each one fits the dish's main ingredients (chicken, egg, pepper, bread):
- Parsleythe original
- Marjoramfits about as well
- Thymefits less well
- Garlicfits less well
Fit is the average pairing score against chicken, egg, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
