Why it works: Carrot and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,053 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Beef Soup
Ingredients
Directions
Cut the beef into small pieces and boil in water for about 1 hour.
Skim off all the fat from the surface.
Add the sliced onions, chopped carrot, celery or celery seed, rice, and season with salt and pepper.
When nearly done, stir in the parsley leaves.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lean beef
- Provides the main protein and savory flavor of the broth.
- Onions
- Adds sweetness and aromatic depth as they soften in the broth.
- Carrot
- Adds mild sweetness and body to the soup.
- Rice
- Thickens the broth slightly and adds starchy body as it cooks.
The step that matters
Skim off all the fat from the surface. Fat rises to the top as the beef simmers and can make the broth greasy and heavy on the palate. Removing it early gives a cleaner, lighter soup.
Swap the onion
How well each one fits the dish's main ingredients (beef, carrot, celery, rice, pepper, parsley):

Fit is the average pairing score against beef, carrot, celery, rice, pepper, parsley. Candidates are from the same food group and used in at least 100 recipes.
