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 ↓
To Make Three Quarts of Good Beef Stock
Ingredients
Directions
Make the stock
Put beef, bones, and water into a stock pot.
Bring to a slow boil, skimming off the scum frequently.
Add salt, onion, leeks, celery, turnip, carrot, parsnip, and pepper.
Simmer for 4 to 5 hours at 180°F to 200°F (82°C to 93°C).
Finish and strain
Skim off the fat, which can be saved for frying.
Remove meat, vegetables, and bones, then strain the stock into a container.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fresh shin of beef
- Releases gelatin and savory flavor into the stock as it simmers slowly.
- Bones
- Add gelatin and body, giving the finished stock a richer mouthfeel.
- Onion
- Contributes sweetness and aromatic depth as it cooks down.
- Carrot
- Adds natural sweetness and color to the broth.
- Leeks
- Add a mild, sweet onion-like aroma to the stock.
The step that matters
Keep the simmer slow and skim the scum. A rolling boil emulsifies fat and impurities into the liquid, making the stock cloudy and greasy. Gentle heat and regular skimming keep it clear and clean-tasting.
Swap the onion
How well each one fits the dish's main ingredients (beef, leek, celery, turnip, carrot, parsnip, pepper):
- Beetrootfits better
- Lettucefits better
- Spinachfits better
