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
- Neck of beef
- Breaks down during long simmering to give the broth body and rich flavor.
- Cornstarch
- Thickens the soup as it heats, giving it a fuller, smoother body.
- Stewed tomatoes
- Add acidity and fruity sweetness that balance the rich beef broth.
- Macaroni
- Adds starchy bulk and body to the soup as it cooks in the broth.
The step that matters
Skim off the fat and foam. Foam and fat rise to the surface as the beef simmers. Removing them keeps the broth clear and stops it tasting greasy.
Swap the clove
How well each one fits the dish's main ingredients (beef, tomato, onion, parsley, pepper):
- Thymefits better
- Garlicfits better
- Celeryfits better
- Clovethe original
Fit is the average pairing score against beef, tomato, onion, parsley, pepper. Candidates are from the same food group and used in at least 100 recipes.
