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 ↓
Egg Soup
Ingredients
Directions
Make the broth
Boil the beef or veal with pepper and salt until well cooked.
Strain the broth into a tureen.
Finish the soup
Beat the yolks of the eggs with chopped parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg yolks thicken the hot broth as they cook, giving the soup a creamy, silky body.
- Beef or veal
- Slow boiling releases flavour and gelatin into the broth, giving the soup its savoury base.
- Rice
- Rice absorbs some liquid as it cooks, adding body and making the soup more filling.
The step that matters
Pour the hot broth over the eggs while stirring continuously. Adding hot liquid to egg yolks while stirring gradually raises their temperature, so they thicken smoothly. Pouring too fast or without stirring can scramble the eggs into lumps.
Swap the parsley
How well each one fits the dish's main ingredients (beef, pepper, egg, rice):
- Turmericfits about as well
- Parsleythe original
- Nutmegfits about as well
- Tarragonfits about as well
Fit is the average pairing score against beef, pepper, egg, rice. Candidates are from the same food group and used in at least 100 recipes.
