Why it works: Turnip and leek match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,046 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
White Broth
Ingredients
Directions
Make the broth
In a large pot, place the veal knuckle and cover it completely with cold water.
Add the salt and bring to a boil, skimming off any scum that rises.
Once boiling, add the carrots, turnip, onion, parsley root, leeks, and celery leaves.
Reduce heat and simmer slowly for about 6 hours, skimming grease and impurities as they appear.
Strain and store
After 6 hours, strain the broth through cheesecloth into a stone crock.
Cover the crock with cotton batting and store in a cool place.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White veal knuckle
- Bone and connective tissue release gelatin, giving the broth body and a silky mouthfeel.
- Carrots
- Add natural sweetness and aromatic depth to the broth.
- Onion
- Contributes savory, mellow flavor as it cooks down into the stock.
- Turnip
- Adds a mild, slightly sweet vegetable flavor to the broth.
The step that matters
Skimming during the simmer. Scum and grease rise to the surface as the broth heats. Removing them keeps the broth clear and clean-tasting instead of cloudy and greasy.
Swap the leek
The recipe marks leek as optional. How well each one fits the dish's main ingredients (carrot, turnip, onion, parsley, celery, veal):
- Leekthe original
- Parsnipfits about as well
- Okrafits less well
- Lettucefits less well
Fit is the average pairing score against carrot, turnip, onion, parsley, celery, veal. Candidates are from the same food group and used in at least 100 recipes.
