Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef trimmings and steak bones
- Release meat flavor and gelatin into the broth, giving body and richness.
- Potatoes
- Break down slightly as they cook, adding starch that thickens the soup.
- Gumbo pods
- Release mucilage as they simmer, adding body and a light thickening to the soup.
- Onion
- Adds savory sweetness and aroma as it softens in the broth.

Fit is the average pairing score against beef, pepper, potato, carrot, parsley. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
