Why it works: Allspice and clove 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 Sour
Ingredients
Directions
Prepare
Clean and cut the ox tails and neat's foot into small joints.
Soak them in water.
Make the soup
In a stew-pan, heat the clarified suet or fat and add the meat; simmer for 10 minutes.

Thicken with browned flour if necessary.
Finish and serve
Before serving, add port wine and mushroom ketchup.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ox tails
- Release gelatin and meaty flavour into the broth during long stewing.
- Neat's foot
- Adds gelatin, giving the soup body and a silky mouthfeel.
- Onions
- Build savoury sweetness and aroma as they soften in the broth.
- Carrot
- Adds natural sweetness and body to the stewed broth.
- Browned flour
- Thickens the broth and adds a toasted, deeper colour and flavour.
- Port wine
- Adds sweetness, depth and a rich fruity note at the end.
The step that matters
Let it stew until the meat is tender enough to remove from the bones. Collagen in tendons and bones breaks down into gelatin only with long, gentle simmering. Rushing this leaves tough meat and a thin, unbodied broth.
Swap the onion
How well each one fits the dish's main ingredients (carrot, turnip, celery, pepper, allspice, clove, flour):
- Parsnipfits better
- Leekfits better
- Arrowrootfits better
- Onionthe original
Fit is the average pairing score against carrot, turnip, celery, pepper, allspice, clove, flour. Candidates are from the same food group and used in at least 100 recipes.
