Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ox-tail
- Releases gelatin during long simmering, giving the soup body and a rich mouthfeel.
- Lean beef
- Contributes savory meaty flavor and tender pieces to the finished soup.
- Onions
- Browning them builds sweet, deep aromatic flavor in the broth.
- Carrots
- Add natural sweetness and body to the soup as they cook down.
- Browned flour
- Starch thickens the liquid, giving the soup a fuller, smoother texture.
- Sherry
- Adds aromatic depth and a slight sweetness that rounds out the broth.
The step that matters
Thicken with browned flour. Flour must be well dispersed in the hot liquid and kept simmering so its starch swells and thickens evenly. Without enough heat and stirring, it forms lumps and leaves a raw, floury taste.
Swap the onion
How well each one fits the dish's main ingredients (beef, carrot, thyme, celery, pepper, sherry, lemon):
- Parsnipfits better

- Capsicumfits better
- Onionthe original
Fit is the average pairing score against beef, carrot, thyme, celery, pepper, sherry, lemon. Candidates are from the same food group and used in at least 100 recipes.
