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 ↓

Ingredients
Directions
Start the broth
Place 6 pounds of beef in a large pot.
Add 4 quarts of water and set near the fire.
Skim the surface when nearly boiling.
Add 1½ tablespoons of coarse sea salt.
Add the vegetables and simmer
Incorporate ½ pound of liver, 2 carrots, 4 turnips, 8 young leeks (or 2 old), 1 head of celery, 2 onions, 1 burnt onion (with a clove in each), and 1 parsnip.
Skim again, then let simmer.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Releases flavor and collagen during slow simmering, giving the broth body and richness.
- Liver
- Adds a deep, savory flavor to the broth.
- Burnt onion
- Contributes colour and a smoky, roasted aroma to the broth.
- Carrots
- Add gentle sweetness that balances the savory beef and liver.
- Leeks
- Add mild onion-like sweetness and aroma to the broth.
The step that matters
Skimming the surface. As the liquid nears boiling, proteins and fat rise as foam. Skimming removes them, keeping the broth clear and preventing a greasy, cloudy result.
Swap the onion
How well each one fits the dish's main ingredients (beef, liver, carrot, turnip, leek, celery, parsnip):
- Beetrootfits better
- Chivefits better
- Lettucefits better
- Onionthe original
Fit is the average pairing score against beef, liver, carrot, turnip, leek, celery, parsnip. Candidates are from the same food group and used in at least 100 recipes.
