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 ↓
Ox- Tail Soup
Ingredients
Directions
Prepare the ox-tail
Wash the ox-tail thoroughly and place it in a kettle of cold water, then bring the water to a boil.
Remove the ox-tail, dry it with a towel, and fry it brown in butter or drippings in a saucepan.
Make the soup
Add flour to the saucepan and stir well, then cover the mixture with water and add the diced carrot, turnip, and potato.
Stick the cloves into the whole onion and add it to the soup along with the herbs.
Season to taste and cook slowly for 2 hours.
Remove the onion and herbs before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ox-tail
- Provides meat and gelatin-rich body that enriches the broth as it simmers.
- Flour
- Thickens the fat and cooking liquid into a smoother, slightly body-rich soup.
- Butter or drippings
- Carries heat for browning the ox-tail and adds rich, savoury flavour.
- Carrot
- Adds sweetness and soft texture as it cooks down into the broth.
- Potato
- Softens during simmering, adding starch that gives the soup more body.
The step that matters
Fry the ox-tail brown. Browning the meat before simmering creates Maillard flavours that a plain boil cannot produce, so the broth tastes deeper and richer.
Swap the clove
How well each one fits the dish's main ingredients (butter, flour, carrot, turnip, potato, onion):
- Parsleyfits better
- Capersfits better
- Thymefits better
- Clovethe original
Fit is the average pairing score against butter, flour, carrot, turnip, potato, onion. Candidates are from the same food group and used in at least 100 recipes.
