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
Make 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; cook for 5 minutes.
Add the ox tail pieces and fry for 10 minutes, stirring occasionally.
Simmer and serve
Transfer the mixture to a stew pan, add the water, and simmer for 3 hours.
About 1 hour before serving, add the shredded celery and thyme, seasoning with pepper and salt.
Serve with a teaspoonful of Yorkshire Relish per half-pint of soup.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ox tail
- Gives the soup its meaty flavour and body as it simmers slowly for hours.
- Dripping
- Carries flavour and adds richness, helping the onions and vegetables brown in the pan.
- Flour
- Cooked in the fat, it thickens the soup and gives it a fuller, silkier body.
- Onions
- Break down during cooking to add sweetness and savoury depth to the broth.
- Carrot
- Adds natural sweetness and body to the soup as it softens.
- Turnip
- Adds earthy sweetness and a soft texture after long simmering.
The step that matters
Fry the ox tail before simmering. Browning the meat in hot fat builds roasted, savoury flavour through the Maillard reaction, which the long simmer alone cannot create. Stirring keeps the flour and vegetables from scorching.
