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, Thick
Ingredients
Directions
Brown the meat and vegetables
Wash and cut the ox tails into 1-inch pieces, dividing the thick pieces into four.
In a stewpan, melt the butter and fry the ox tails until browned.
Add the sliced vegetables and diced ham to the pan and fry for a few minutes.
Pour in 1 quart of water and stir over high heat for 15 minutes.
Simmer the soup
Add 2 quarts of stock, sweet herbs, bay leaf, salt, peppercorns, cloves, and sugar.
Simmer gently until the meat is tender and easily separates from the bones.
Remove the meat, strain the soup, and skim off the fat.
Thicken and serve
In a saucepan, brown the fat and mix in the flour to create a smooth paste.
Thicken the soup with the flour mixture and stir in the mushroom ketchup.
Add the pieces of tail back to the soup and simmer for an additional 15 minutes.
Serve hot with fresh rolls.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ox tails
- Provide the meat and gelatin-rich body that flavours the broth as they cook.
- Fresh butter
- Carries the initial frying and browns the ox tails for deeper flavour.
- Fine flour
- Thickens the soup when browned in fat and stirred in as a paste.
- Onions
- Break down during frying and simmering to add sweetness and savoury depth.
- Carrots
- Add sweetness and body to the stock as they soften during simmering.
- Mushroom ketchup
- Adds concentrated savoury, umami flavour to the finished soup.
The step that matters
Making the flour thickening. Flour must be cooked in the fat until smooth and then stirred into the hot soup; otherwise it clumps and stays starchy instead of thickening evenly.
Swap the onion
How well each one fits the dish's main ingredients (butter, carrot, turnip, celery, ham, clove, sugar):
- Leekfits better

- Mustardfits better
- Onionthe original
Fit is the average pairing score against butter, carrot, turnip, celery, ham, clove, sugar. Candidates are from the same food group and used in at least 100 recipes.
