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
serves 2 (1 cup each)Ingredients
Directions
Prepare the stock
Wash the ox-tail in cold water and place it in a porcelain or agate kettle.
Pour in 5 quarts of cold water and soak for 2 hours.
Bring to a boil gradually and simmer until the meat falls off the bones.
Add the chopped carrot, leek, celery, parsley, and tomatoes.
When the vegetables are soft, strain the soup and let it cool.
Finish and store
The next day, skim off the fat and heat the soup.
Add salt, browned flour, mixed spices, cayenne, and sugar.
Seal in a glass preserving jar; it will keep for 2 weeks in cold weather.
Use 1 cup of soup for 2 people, adding a few spoonfuls of water when reheating.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ox-tail
- Releases collagen and meat flavour into the broth as it simmers slowly.
- Browned flour
- Thickens the soup slightly and adds a toasted, deeper flavour.
- Tomatoes
- Add acidity and savoury body to the broth.
- Carrot
- Adds natural sweetness and body to the broth as it softens.
The step that matters
Simmering the ox-tail gradually. Bringing the water to a boil gradually and then keeping it at a gentle simmer lets collagen break down slowly into gelatin, giving a rich broth with tender meat. A hard rolling boil can toughen the meat and cloud the soup.
Swap the tomato
How well each one fits the dish's main ingredients (carrot, leek, celery, parsley, flour, clove, allspice):
- Parsnipfits better
- Turnipfits better
- Shallotfits better
- Tomatothe original
Fit is the average pairing score against carrot, leek, celery, parsley, flour, clove, allspice. Candidates are from the same food group and used in at least 100 recipes.
