Ingredients
Directions
Prepare
Combine the veal, shanks, trimmings, carrot, celery, onions, leeks, and turnip in a large pot.
Heat over a brisk fire until it catches but does not burn.
Make the broth
Add 5 quarts of soft water and bring to a boil, then skim off the scum.
Add 1 pint of cold water to remove more scum.
Reduce heat and simmer slowly for 4 hours.
Finish
Remove from heat and let settle.
Skim off the fat and strain the soup.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal knuckle or scrag
- Releases gelatin and savoury flavour into the broth during long simmering.
- Mutton shanks or leg knuckle
- Adds rich meaty flavour and body to the broth as it simmers.
- Onions
- Contribute sweetness and aromatic depth to the broth base.
- Celery
- Adds a fresh, aromatic vegetable flavour to the broth.
- Leeks
- Add mild onion-like sweetness and aroma to the broth.
The step that matters
Skimming the scum. Scum is coagulated protein and impurities that rise as the liquid heats. Skimming it early keeps the broth clear and clean-tasting, which is why it is done after the boil and again after adding cold water.
