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
Brown the base
In a frying pan, melt the dripping over medium heat and stir in the flour.
Add the sliced onions, diced carrot, and diced turnip to the pan and cook for 5 minutes.
Add the ox tail pieces and fry for about 10 minutes, stirring occasionally.
Simmer and season
Transfer the contents of the frying pan to a stew pan, add the water, and simmer for about 3 hours.
One hour before serving, add the shredded celery and thyme, seasoning with pepper and salt to taste.
Before serving, stir in 1 teaspoon of Yorkshire Relish for flavor.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ox tail
- Connective tissue breaks down during long simmering, giving the soup body and richness.
- Dripping
- Fat carries flavor and helps brown the vegetables and meat.
- Flour
- Cooked into the fat, it thickens the soup as it simmers.
- Onions
- Softened and sweetened as they cook, they build the savory base.
- Carrot
- Softens and adds natural sweetness to the broth.
- Turnip
- Adds mild, earthy sweetness and body as it softens.
The step that matters
Simmer the ox tail gently for the full time. Ox tail is rich in connective tissue that needs long, gentle heat to break down into gelatin. A hard boil toughens the meat and can make the broth cloudy and greasy.
Swap the onion
How well each one fits the dish's main ingredients (flour, carrot, turnip, celery, thyme, pepper):
- Parsnipfits better
- Leekfits better
- Okrafits better
- Onionthe original
Fit is the average pairing score against flour, carrot, turnip, celery, thyme, pepper. Candidates are from the same food group and used in at least 100 recipes.
