Why it works: Carrot and clove match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 5,873 recipes. Both carry cuminaldehyde, which smells Spicy, cumin. The science ↓
Ox-tail Soup
Ingredients
Directions
Prepare the ox-tails
Cut the ox-tails at the joints into pieces of similar size.
Soak them in cold water with a little coarse sea salt for 2 hours to remove the blood.
Drain and dry the ox-tails with a clean cloth.
Make the soup
In a 3-quart stewpan, melt the butter and brown the ox-tails with a few pieces of lean beef.
Add the stock or water, the onion with cloves, and the bouquet garni.
Bring to a boil, then skim the surface.
Simmer for 3 to 4 hours until the meat easily comes off the bones.
Slice the carrots and cook them with the button onions in a little stock.
Serve
Remove the ox-tail meat from the soup, discard the bones, and place the meat in a tureen with the carrots and onions.
Strain the soup over the meat and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ox-tails
- Provide the meat and gelatine-rich body that gives the soup its flavour and richness.
- Butter
- Browns the ox-tails and carries flavour from the meat into the soup.
- Button onions
- Add sweetness and aromatic depth as they cook down in the soup.
- Carrots
- Add natural sweetness and a soft texture to the finished soup.
- Stock or water
- Forms the liquid base in which the meat and aromatics simmer.
The step that matters
Skim the surface after boiling. Bringing the liquid to a boil releases foam and impurities; skimming removes them so the soup stays clear and clean-tasting.
Swap the clove
How well each one fits the dish's main ingredients (carrot, onion, butter):
- Parsleyfits better
- Celeryfits better
- Thymefits better
- Clovethe original
Fit is the average pairing score against carrot, onion, butter. Candidates are from the same food group and used in at least 100 recipes.
