Why it works: Leek and turnip 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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chuck beef
- Provides collagen and meat flavor that dissolve into the liquid, giving the stock body.
- Onion
- Adds sweetness and savory depth as it cooks slowly in the liquid.
- Carrots
- Contribute natural sweetness and aromatic flavor to the broth.
- Leeks
- Add a mild, sweet onion-like aroma to the stock.
- Celery
- Adds aromatic, savory vegetable flavor to the broth.
The step that matters
Skim off the foam at the boil. Foam is made of coagulated proteins and impurities that would cloud the stock and taint its flavor if left to recombine. Skimming early keeps the broth clear and clean-tasting.
Swap the onion
How well each one fits the dish's main ingredients (beef, parsley, thyme, carrot, leek, turnip, celery):
- Parsnipfits better
- Shallotfits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against beef, parsley, thyme, carrot, leek, turnip, celery. Candidates are from the same food group and used in at least 100 recipes.
