Why it works: Carrot and turnip 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 ↓
Bone Soup
Ingredients
Directions
Simmer the bones
Break the bones and place them in a saucepan with 1½ pints of cold water for every pound of bone.
Boil for three to four hours.
Add the vegetables and finish

Boil for another hour, then remove the bones and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bones
- Long simmering draws gelatin and flavour from the bones into the water, giving the soup body.
- Broken rice
- Its starch thickens the soup as it cooks.
- Carrots
- Add sweetness and colour to the broth as they soften.
- Turnips
- Add mild sweetness and soft texture as they cook through.
- Onion
- Adds savoury aroma and depth to the broth.
The step that matters
Boiling the bones for three to four hours. Bones release gelatin and flavour slowly over long cooking. Stopping early leaves a thin, weak broth, so the bones need the full simmer before the vegetables go in.
