Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Long gentle boiling breaks down tough connective tissue, making the meat tender and flavoring the broth.
- Onions
- Release sweetness and savory aroma into the broth as they cook.
- Carrot
- Adds natural sweetness and a firm texture that holds up to simmering.
- Cabbage
- Contributes soft, mild body and bulk to the soup.
- Potatoes
- Their starch softens and gives the broth more body as they cook.
- Tomatoes
- Add acidity and fruity flavor that balances the rich beef broth.
The step that matters
Adding the vegetables forty minutes before serving. Carrot and cabbage cook much faster than beef. Adding them too early can turn them mushy, while adding them too late leaves them crunchy and underdone.
