Why it works: Carrot and celery match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 10,173 recipes. Both carry myristicin, which smells spice, warm. The science ↓
Ox-tail Soup
Ingredients
Directions
Prepare
Cut the ox-tails into joints.
Make the broth
In a large pot, combine the ox-tails, gravy beef, ham bone, water, carrots, turnips, celery, onions, bread crust, sweet herbs, cloves, and peppercorns.
Boil gently for several hours until the ox-tails are tender.
Remove the ox-tails and let the beef and vegetables boil for an additional 4 hours.
Strain the broth and remove the fat as you would for clear gravy soup.
Finish the soup
If not using ham bones, add ketchup or prepared sauces, wine, and cayenne to taste.
Return the ox-tails to the pot along with cut pieces of carrot and turnip.
For a thicker soup, thicken the broth with brown roux before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ox-tails
- Long simmering breaks down connective tissue, giving the broth body and tender meat.
- Gravy beef
- Slow simmering releases its flavour and gelatin into the broth, enriching the soup.
- Ham bone
- Adds savoury, smoky depth and gelatin to the broth during long simmering.
- Brown roux
- Flour and fat cooked together thicken the broth, giving it a smooth, fuller texture.
The step that matters
Removing the fat from the broth. Fat rises and floats on hot broth and can make the soup greasy. Straining and skimming it off once the broth is strained gives a clean, clear result.
Swap the clove
How well each one fits the dish's main ingredients (beef, ham, onion, carrot, turnip, celery, bread):
- Parsleyfits better
- Marjoramfits better
- Thymefits better
- Clovethe original
Fit is the average pairing score against beef, ham, onion, carrot, turnip, celery, bread. Candidates are from the same food group and used in at least 100 recipes.
