Why it works: Turnip and carrot match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,002 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Stock From Bones
Ingredients
Directions
Prepare
Remove as much marrow and fat from the bones as possible.
Place the bones in a pot and cover them completely with cold water.
Add the onions, carrot, turnip, and peppercorns.
Simmer and strain
Boil on low heat for 8 hours, ensuring the water does not reduce too much; add more water if necessary.
Strain the stock through a sieve.
Chill and finish
Refrigerate overnight and remove the fat before use.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Raw bones
- Release collagen and gelatin into the water, giving the broth body and richness.
- Onions
- Add sweetness and savory depth to the finished stock.
- Carrot
- Adds sweetness and a mild aromatic background to the stock.
- Turnip
- Contributes subtle sweetness and earthy aroma to the broth.
The step that matters
Keep the water level topped up during the long simmer. Long, gentle simmering slowly extracts gelatin and flavor from the bones. If the water drops and the bones are exposed, the broth becomes concentrated and can taste harsh or dull, so keeping the bones submerged matters.
Swap the onion
How well each one fits the dish's main ingredients (turnip, carrot):
- Parsnipfits better
- Leekfits better
- Beetrootfits better
- Onionthe original
Fit is the average pairing score against turnip, carrot. Candidates are from the same food group and used in at least 100 recipes.
