Ingredients
Directions
Prepare
Remove the bone from the shin of beef, break it up, and tie the meat into a neat shape with kitchen twine.
Place the beef and bone into a large pot with 4 quarts of cold water.
If using a fowl or partridge, split it in half and add it to the pot.
Chop the carrots, turnips, parsnip, leeks, onions, and parsley root.
Simmer
Bring the contents to a simmer over low heat, adding a little salt.
Remove scum carefully from the surface.
Add the chopped vegetables, bay leaf, parsley root, and pepper to the pot when it begins to boil.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shin of beef
- Provides rich meat flavour and gelatin that gives the broth body as it simmers slowly.
- Fowl or partridge
- Adds additional savoury flavour and richness to the broth as it cooks.
- Carrots
- Contribute natural sweetness and aroma to the broth as they soften in the liquid.
- Leeks
- Add a mild onion-like aroma and sweetness to the broth.
- Onions
- Add savoury depth and sweetness to the broth as they cook down.
The step that matters
Bringing the pot to a simmer. Heating gently over low heat and skimming scum keeps the broth clear. A hard boil makes fat and impurities emulsify into the liquid, leaving it cloudy and greasy.
