Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's head
- Forms the main body of the soup and gives rich flavour and gelatin as it cooks.
- Pearl barley
- Thickens the broth and adds body as it softens during cooking.
- Stewed celery
- Adds savoury, aromatic flavour to the broth.
The step that matters
Cook the head until it is tender. The head contains tough connective tissue and gelatin-rich parts that need long, gentle simmering to soften. Boiling hard can toughen the meat and cloud the broth, so it should stay at a gentle simmer until fully tender.
Swap the mace
How well each one fits the dish's main ingredients (onion, clove, barley, celery, pepper):
- Thymefits better
- Parsleyfits better
- Marjoramfits better
- Macethe original
Fit is the average pairing score against onion, clove, barley, celery, pepper. Candidates are from the same food group and used in at least 100 recipes.
