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.
Simmer and cool
Bring to a boil, then reduce heat and simmer for 3 hours, skimming off any scum that rises.
Remove the tails, strain the broth through a fine sieve into a clean pan, and set aside to cool overnight.
Finish the soup
The next day, cut the meat into bite-sized pieces, skim the broth, and return 2 quarts of it to the pan with the meat.
Simmer gently for another 30 minutes.
Season with salt, Cayenne pepper, and a splash of wine or brandy if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ox tails
- Supply the meat and collagen that give the broth body and a rich, savoury flavour.
- Onions
- Add sweetness and aromatic depth to the broth as they simmer for hours.
- Cloves
- Contribute a warm, aromatic spice note to the broth.
- Allspice
- Adds a warm, peppery aroma that complements the beef flavour.
The step that matters
Skimming the scum during the 3-hour simmer. Impurities and fat that rise early cloud the broth and can taste bitter. Skimming them as they form keeps the soup clear and clean-flavoured.
Swap the onion
How well each one fits the dish's main ingredients (clove, allspice, pepper):
- Carrotfits better
- Capsicumfits better
- Mustardfits better
- Onionthe original
Fit is the average pairing score against clove, allspice, pepper. Candidates are from the same food group and used in at least 100 recipes.
