Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Carrots
Provide the main flavour and body, thickening the soup when pulped.
Celery
Adds aromatic flavour to the broth as it simmers.
Onion
Adds savoury, aromatic depth to the broth.
Beef bones
Release flavour and gelatin into the water during long simmering, enriching the broth.

The step that matters

Skim off any foam. Foam rising during the initial boil contains impurities that can cloud the broth and taint its flavour. Removing it early keeps the soup clear and clean-tasting before the long simmer.

Swap the onion

How well each one fits the dish's main ingredients (carrot, celery, beef, pepper):

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