Why it works: Carrot and celery match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 10,173 recipes. Both carry myristicin, which smells spice, warm. The science ↓
Vegetable Soup
Ingredients
Directions
Make the stock
Wash the marrow bone and lean meat well.
Cover with cold water and simmer for a whole day, adding water as it boils away.
Let the stock stand overnight and skim off some of the fat.
Make the soup
Put the stock on the stove and add the chopped onion, carrot, potatoes, turnip, celery, and cabbage.
Boil for three hours.
Soak the corn and barley in cold water.
Add the soaked barley and corn to the soup half an hour before serving, stirring often.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Marrow bone
- Releases flavor and gelatin into the stock, giving the soup body and richness.
- Lean meat
- Flavors the stock as it simmers and can be served as part of the soup.
- Barley
- Swells as it cooks, thickening the soup and adding a chewy texture.
- Potatoes
- Soften during long simmering, adding starch that gives body to the broth.
- Corn
- Adds sweetness and a tender bite to the finished soup.
The step that matters
Skim the fat after standing overnight. Fat that rises and sets on cold stock can make the soup greasy. Removing it while the stock is cold leaves a cleaner, lighter broth.
Swap the cabbage
How well each one fits the dish's main ingredients (meat, onion, carrot, potato, turnip, celery, corn):
- Leekfits better
- Parsnipfits better
- Okrafits better
- Cabbagethe original
Fit is the average pairing score against meat, onion, carrot, potato, turnip, celery, corn. Candidates are from the same food group and used in at least 100 recipes.
