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 gelatinous body of the soup when stewed until very tender.
- Vegetables
- Add flavour, body and sweetness to the strained broth as the soup simmers.
- Good stock
- Adds savoury depth and a richer base to the soup.
The step that matters
Skimming the foam while the soup boils gently. Foam and impurities rise to the surface as the liquid heats. Skimming them off keeps the soup clear and free of bitter or greasy flavours. Boiling hard instead of gently would break up the liquid and cloud it.
Swap the onion
How well each one fits the dish's main ingredients (carrot, celery, pepper, parsley):
