Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Provides the main flavor and body of the soup as it simmers.
- Flour
- Coats the meat so it browns, and later thickens the soup.
- Onions
- Add sweetness and savory depth, and their skins contribute color to the broth.
- Celery
- Adds aromatic flavor to the simmering broth.
- Carrot
- Adds sweetness and body to the broth as it cooks.
- Turnip
- Adds mild sweetness and body to the broth as it cooks.
The step that matters
Fry the dredged meat with the onions until browned. Browning through the Maillard reaction builds deep, roasted flavor and color in the broth. Pale meat yields a flatter, less colorful soup, so the meat should be well browned before liquid is added.
Swap the onion

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