Why it works: Turnip and capers match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 145 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Ox-tails
Ingredients
Directions
Brown the oxtail
In a stewpan, melt the butter and brown the oxtail pieces with the chopped onion over medium heat.
Peel and boil the button onions in 3 pints of water for 15–20 minutes, then set aside.
Pour the boiling water from the button onions over the oxtails, adding enough boiling water to cover them.
Simmer
Add the sliced carrots and simmer for 20 minutes before adding the turnips.
Ensure the oxtails and vegetables do not stew too quickly or too long.
Once tender, strain the gravy through a sieve and skim off the fat.
Thicken and serve
In a separate pan, melt 1 ounce of butter and stir in enough flour to thicken the gravy.
Gradually add the strained gravy, stirring until it boils, then let it simmer gently.
Arrange the oxtails around a serving dish, place the vegetables in the center, and pour the gravy over.
Warm the button onions in boiling water and place them around the dish just before serving.
Optionally, add minced gherkins or capers to the dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oxtails
- Long simmering breaks down connective tissue, making the meat tender and gelatinous in the gravy.
- Butter
- Browning the oxtail and onion adds savoury flavour, and butter with flour forms the thickening roux.
- Flour
- Combined with melted butter, it forms a roux that thickens the strained gravy.
- Carrots
- Add sweetness and body to the stew as they soften during simmering.
- Turnips
- Add a mild, slightly peppery flavour and soft texture to the stew.
The step that matters
Keep the simmer gentle. Boiling or stewing too hard toughens the meat's proteins and breaks up the vegetables, so the oxtail should cook slowly until tender and the vegetables are added at the right time.
Swap the capers
The recipe marks capers as optional. How well each one fits the dish's main ingredients (butter, onion, carrot, turnip, flour, pepper):
- Parsleyfits better
- Thymefits about as well
- Celeryfits about as well
- Capersthe original
Fit is the average pairing score against butter, onion, carrot, turnip, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
