Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's head
- Provides the gelatinous meat and skin that give the soup its body and texture.
- Gravy beef
- Adds deep meaty flavour to the broth that the soup is built on.
- Knuckle of veal
- Contributes gelatin and body to the broth, giving it a richer mouthfeel.
- Flour
- Thickens the strained soup together with butter into a smoother, lightly body-rich liquid.
- Madeira wine
- Adds sweetness and aromatic depth to the seasoned soup.
- Lemon juice
- Brightens the rich broth with acidity that balances its heaviness.
The step that matters
Boil the head until tender before straining. The head must cook fully so its collagen softens and breaks down into gelatin; undercooked pieces stay tough and chewy, and the broth will lack body.
Swap the sage
How well each one fits the dish's main ingredients (beef, veal, turnip, carrot, onion, celery, ham):
- Parsleyfits better
- Marjoramfits better
- Thymefits better
- Sagethe original
Fit is the average pairing score against beef, veal, turnip, carrot, onion, celery, ham. Candidates are from the same food group and used in at least 100 recipes.
