Why it works: Clove and allspice match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 7,874 recipes. Both carry estragole, which smells anise, licorice. The science ↓
Ox-tail Soup
Ingredients
Directions
Prepare
Soak the ox tails in warm water while preparing the vegetables.
In a large stew pan, combine the ox tails, cloves, onions, allspice, black pepper, and cover with cold water.
Make the broth
Skim off any scum that rises, then cover the pot and simmer gently for about 2 hours until the meat is tender.
Remove the meat from the bones and cut it into bite-sized pieces.
Skim the broth and strain it through a sieve.
Thicken and finish
For a thickened soup, heat the fat in a clean stew pan, add flour to make a paste, and gradually stir in the broth.
Let it simmer for another 30 minutes, skimming and straining it until smooth.
Add the meat back into the soup, along with mushroom ketchup, wine, and season with salt.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ox tails
- Slow simmering breaks down connective tissue, making the meat tender and enriching the broth with body.
- Flour
- Forms a paste with the fat that thickens the broth as it is stirred in.
- Fat from the broth
- Carries flour into a smooth paste and adds richness and mouthfeel to the soup.
- Onions
- Release sweetness and savory depth into the broth during long simmering.
- Wine
- Adds acidity and aromatic depth to the finished soup.
The step that matters
Stirring the broth into the flour paste. Adding liquid gradually while stirring keeps the flour dispersed, so it thickens smoothly instead of forming lumps.
Swap the onion
How well each one fits the dish's main ingredients (clove, allspice, pepper, flour, mushroom, ketchup, wine):
- Shallotfits better
- Capsicumfits better
- Carrotfits better
- Onionthe original
Fit is the average pairing score against clove, allspice, pepper, flour, mushroom, ketchup, wine. Candidates are from the same food group and used in at least 100 recipes.
