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 ↓
Potted Ox Tail
Ingredients
Directions
Prepare the base
Place the ox tail pieces in a large casserole.
In a frying pan, cook the bacon until crispy.
Add the sliced onion and sugar to the pan, and brown well.
Pour the boiling water into the pan, boil briefly, and strain into the casserole.
Add the carrot, celery, cloves, and bay leaf to the casserole.
Simmer the meat
Cover and simmer slowly for 2 hours.
Add the salt and white wine halfway through cooking.
Once the meat is tender, strain the stock.
Make the sauce and serve
In a separate pan, melt the butter and brown the flour.
Gradually add the strained stock, cooking until smooth.
Pour the sauce over the meat in the casserole, heat together, and serve.

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 collagen that become tender and give the stock body during slow simmering.
- Flour
- Browned in butter and mixed with stock, it thickens the sauce.
- Butter
- Carries the flour for browning, adding a nutty flavour to the sauce base.
- Bacon
- Its rendered fat and browned bits add savoury depth to the stock.
- Onion
- Browned with sugar, it adds sweetness and deepens the colour and flavour of the stock.
- White wine
- Adds acidity and aroma to the braising liquid.
The step that matters
Browning the flour in butter. Cooking the flour long enough to lose its raw taste, but stopping before it darkens too much, sets the flavour and thickening power of the sauce. Adding stock gradually while stirring prevents lumps.
Swap the onion
How well each one fits the dish's main ingredients (sugar, carrot, celery, clove, white wine, butter, flour):
- Leekfits better
- Parsnipfits better
- Turnipfits better
- Onionthe original
Fit is the average pairing score against sugar, carrot, celery, clove, white wine, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
