Why it works: Clove and pepper match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 17,451 recipes. Both carry ethyl octanoate, which smells fruity, wine. The science ↓
Ox-tail Soup
Ingredients
Directions
Prepare
Divide the ox tail at the joints and soak in warm water.
Fry the tail slices in a saucepan.
Add cloves, onions, sweet herbs, black pepper, and mace.
Simmer the soup
Cover with water and boil, skimming off any foam.
Simmer gently for 2-3 hours until the meat is tender.
Remove the meat, cut into small pieces, and set aside.
Strain the broth through a cloth or sieve.
Finish and serve
Add wine and mushroom catsup, then return the meat to the soup.
Bring to a boil before serving.

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 gelatin during long simmering, giving the broth body and tender meat.
- Onions
- Add sweetness and savory depth as they soften and release flavor into the broth.
- Wine
- Adds acidity and aroma that brighten the rich, fatty broth.
- Mushroom catsup
- Adds concentrated savory, umami flavor to the broth.
The step that matters
Skimming off the foam after boiling. Foam carries coagulated proteins and impurities to the surface. Removing it as it forms keeps the broth clear and free of bitter or scummy flavors.
Swap the mace
How well each one fits the dish's main ingredients (clove, onion, pepper, wine, mushroom):
- Thymefits better
- Garlicfits better
- Rosemaryfits better
- Macethe original
Fit is the average pairing score against clove, onion, pepper, wine, mushroom. Candidates are from the same food group and used in at least 100 recipes.
