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 ↓
Stock, and Clear Soups
Ingredients
Directions
Make the stock
Combine meat and bones in a large pot.
Add chopped vegetables: carrots, onions, leeks, celery, turnips, and parsnip.
Cover with water and bring to a simmer.
Maintain a steady heat without sudden temperature changes.
Strain and clarify
After cooking, strain the liquid into an earthenware or enamelled basin.
Skim off any fat once cooled, then pour off gently without disturbing the dregs.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Meat
- Releases savory flavour and gelatin into the liquid as it simmers.
- Bones
- Contribute body, gelatin and depth of flavour to the stock.
- Onions
- Add sweetness and aromatic depth to the stock.
- Carrots
- Contribute natural sweetness and a rounded background flavour.
The step that matters
Maintain a steady heat without sudden temperature changes. Boiling vigorously emulsifies fat and breaks up particles into the liquid, leaving the stock cloudy. A gentle, steady simmer keeps it clear and easier to skim.

Fit is the average pairing score against meat, carrot, leek, celery, turnip, parsnip. Candidates are from the same food group and used in at least 100 recipes.
