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
Prepare the beef
Cut the beef shin bone into short pieces to expose the marrow.
Wash the pieces in cold water.
Rub the meat with ½ tablespoon salt and ½ tablespoon pepper.
Place the meat in a pot with 4 quarts of water.
Simmer the soup
Bring to a boil over medium heat and skim off any scum that rises.
Cover and simmer gently for 2 hours.
Skim again.
Add the carrot, turnip, onion, parsley, potatoes, and pearl barley.
Cover and simmer gently for 1 hour.
Add ½ tablespoon salt.
Add a thickening made from 1 tablespoon flour mixed with ½ cup water and stir it in.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef shin bone
- Its marrow and connective tissue enrich the broth with body and savory flavor during long simmering.
- Pearl barley
- Releases starch as it cooks, adding body and thickness to the soup.
- Potatoes
- Soften during simmering and add starch, giving the soup substance and a mild sweetness.
- Wheat flour
- Mixed with water and stirred in, it thickens the broth by gelatinizing its starch.
The step that matters
Stir the flour thickening into the simmering soup. Flour mixed with water must be stirred in well and cooked, or it clumps and leaves a raw floury taste. Starch needs heat to swell and thicken the broth evenly.
Swap the onion
How well each one fits the dish's main ingredients (beef, pepper, carrot, turnip, parsley, potato, barley):
- Leekfits better
- Parsnipfits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against beef, pepper, carrot, turnip, parsley, potato, barley. Candidates are from the same food group and used in at least 100 recipes.
