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 ↓
Oxtail Soup
Ingredients
Directions
Prepare the base
In a saucepan, combine the prepared vegetables, dried herbs, and half the butter. Fry for about 10 minutes.
Add the water and seasonings, then simmer for 2 hours.
Make the roux
In another pan, melt the remaining butter and slowly stir in the flour. Cook for a few minutes.
Combine and serve
Strain the contents of the first saucepan into the second pan with the flour mixture.
Add the contents of the tin of oxtail and the diced ham. Heat thoroughly.
Adjust seasoning if necessary, and the soup is ready to serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the butter and stock mixture into a smooth, body-rich soup.
- Butter
- Carries the frying of the vegetables and forms the base for the flour thickener.
- Oxtail
- Contributes meaty flavour and richness to the broth during the long simmer.
- Onions
- Soften and sweeten while frying, adding savoury depth to the soup.
- Carrots
- Add natural sweetness and body to the vegetable base.
The step that matters
Cooking the flour in the butter. Cooking the flour in melted butter for a few minutes removes its raw taste and lets it thicken smoothly when the liquid is added, so the soup does not turn lumpy or pasty.
