Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Knuckle of veal
- Releases gelatin and flavour into the water, giving the soup body.
- Lean beef
- Adds meaty flavour to the broth as it cooks until tender.
- Bacon
- Adds smoky, savoury fat that flavours the broth.
- Onions
- Contribute sweetness and aroma as they cook into the broth.
- Carrots
- Add gentle sweetness and colour to the soup.
The step that matters
Do not let the meat brown. Browning meat during the initial simmer changes the flavour and turns the broth darker and heavier. A clear soup stays pale and clean when the meat is gently simmered rather than seared.
