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 the soup
Cut the ox-tails into joints.
In a large pot, boil the ox-tails, beef, ham bone, carrots, turnips, celery, onions, bread, herbs, cloves, and peppercorns in enough water for several hours.
Simmer and strain
Remove the ox-tails when tender and continue boiling the remaining ingredients for 4 more hours.
Strain the broth and remove the fat as you would for clear gravy soup.
Finish and serve
If not using ham bones, add ketchup or prepared sauces, wine, and cayenne to taste.
Return the ox-tails to the soup and add pieces of carrot and turnip cut into fancy shapes.
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
- Release gelatin and rich flavor into the broth as they simmer for hours.
- Gravy beef
- Adds meaty flavor and body to the broth during long simmering.
- Ham bone
- Contributes savory, smoky depth to the stock as it cooks.
- Brown roux
- Thickens the broth and adds a toasted, nutty flavor and body.
The step that matters
Removing the fat from the strained broth. Fat floats on top of a long-simmered broth and, if left in, makes the soup greasy and cloudy. Skimming and straining while the broth is hot and separated gives a clearer, cleaner result.
Swap the clove
How well each one fits the dish's main ingredients (beef, ham, carrot, turnip, onion, celery, bread):
- Parsleyfits better
- Marjoramfits better
- Thymefits better
- Clovethe original
Fit is the average pairing score against beef, ham, carrot, turnip, onion, celery, bread. Candidates are from the same food group and used in at least 100 recipes.
