Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ox-tail
- Provides the meat and gelatin that give the soup its body and rich flavour.
- Butter
- Adds fat that carries flavour and rounds out the richness of the broth.
- Carrots
- Contribute sweetness and aromatic flavour to the broth as they cook.
The step that matters
Boiling the ox-tail before simmering. Brief boiling then straining removes scum and impurities from the meat, which keeps the finished soup clear and cleanly flavoured.
Swap the onion
How well each one fits the dish's main ingredients (butter, carrot, turnip, clove, celery, flour, thyme):
- Parsnipfits better
- Leekfits better
- Shallotfits better
