Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oxtail (in the method)
- Gives the soup its main meaty flavour and body as it simmers.
- Butter
- Fat that browns the vegetables and carries flavour into the soup.
- Flour
- Browned in butter and stirred in, it thickens the soup and adds a toasty note.
- Onion
- Softens and sweetens during frying, adding savoury depth to the broth.
- Celery
- Adds aromatic, savoury flavour to the simmering broth.
The step that matters
Fry the flour in butter until browned. Flour cooked in fat must be stirred and watched closely; under-cooked flour tastes raw and pasty, while over-browned flour turns bitter and darkens the soup unevenly.
Swap the clove
How well each one fits the dish's main ingredients (onion, celery, butter, flour, carrot, turnip):
- Parsleyfits better
- Capersfits better
- Thymefits better
- Clovethe original
Fit is the average pairing score against onion, celery, butter, flour, carrot, turnip. Candidates are from the same food group and used in at least 100 recipes.
