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 per portion when reheating)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 the water to a boil gradually and simmer until the meat falls off the bones.
Add the chopped carrot, leek, celery, parsley, and tomatoes.
Once the vegetables are soft, strain the soup and let it cool.
Finish and store
The next day, skim off the fat and reheat the soup.
Add salt, browned flour, mixed spices, cayenne, and sugar.
Store in a glass preserving jar; it will keep for 2 weeks in cold weather.
When reheating, use 1 cup of soup for 2 people and add a few spoonfuls of water.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ox-tail
- Breaks down into rich meat and gelatin that give the soup body and flavour.
- Tomatoes
- Add acidity and a bright, savoury note to the broth.
- Browned flour
- Thickens the soup slightly and adds a toasted, nutty flavour.
- Carrot
- Releases sweetness and aromatic flavour into the broth as it cooks.
The step that matters
Skim off the fat the next day. Fat that has cooled and solidified on the surface makes the soup greasy if left in. Chilling the strained soup overnight lets the fat set on top so it lifts off cleanly before reheating.
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.
