Why it works: Allspice and pepper match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 6,395 recipes. Both carry estragole, which smells anise, licorice. The science ↓
Ox Tail Soup
Ingredients
Directions
Prepare the tails
Wash, soak, and clean the ox tails thoroughly.
Place the tails in a pot with 4 quarts of cold water for each tail.
Skim off any scum that rises as the water heats.
Add an onion and 8 to 10 black peppercorns and allspice berries for each tail.
Cover and simmer slowly until the meat is tender and easily separates from the bones.
Make the broth
Remove the tails, scrape off the meat, and cut it into small pieces.
Skim the broth and strain it through a sieve.
If thickening, knead 2 tablespoons of fat with flour, mix it into the broth, and simmer for another 30 minutes.
If not thickening, return the meat to the broth and warm it up.
Season and serve
Add a glass of wine, mushroom catsup, cayenne, and salt to taste.
Simmer for a few minutes 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 meat and gelatin that give the soup body and richness as they simmer.
- Fat from the broth
- Carries flavour and, kneaded with flour, helps thicken the broth.
- Wine
- Adds acidity and aromatic depth to the finished soup.
- Mushroom catsup
- Contributes concentrated savoury, umami flavour to the broth.
The step that matters
Skimming the scum as the water heats. Scum is coagulated protein and impurities that rise as water warms. Removing it early keeps the broth clear and clean-tasting rather than cloudy or greasy.
Swap the onion
How well each one fits the dish's main ingredients (allspice, wine, mushroom, pepper):
- Capsicumfits better
- Shallotfits better
- Tomatofits better
- Onionthe original
Fit is the average pairing score against allspice, wine, mushroom, pepper. Candidates are from the same food group and used in at least 100 recipes.
