Why it works: Carrot and turnip match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,002 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Ox-tail Stewed
Ingredients
Directions
Prepare the oxtail
Wash the ox-tail in warm water and cut it into joints, halving the larger ones.
Dry the pieces and mix flour, salt, and pepper on a plate.
Rub each piece of tail with the flour mixture.
Brown and stew
Heat dripping in a stew-pan and fry the pieces of tail until browned, then remove them.
Pour out excess fat, return the tail to the pan, and add chopped onion, water, and ketchup.
Stew gently for 1.5 hours.
Add carrot and turnip pieces and stew for an additional 45 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ox-tail
- Slow stewing breaks down connective tissue, making the meat tender and the broth rich.
- Flour
- Coats the meat so it browns well and helps thicken the stewing liquid.
- Dripping
- Conducts heat for frying the tail and carries flavour into the browned surface.
- Ketchup
- Adds tomato acidity and sweetness, deepening the colour and savoury flavour of the sauce.
- Onion
- Releases sugars and aromatic compounds during stewing, sweetening and flavouring the broth.
The step that matters
Browning the floured tail. Frying the floured pieces until browned creates Maillard flavour and colour on the surface. Pale meat added to the stew results in a flat, greyish sauce, so the pieces should be properly browned before liquid goes in.
Swap the onion
How well each one fits the dish's main ingredients (flour, ketchup, carrot, turnip, pepper):
- Parsnipfits better
- Leekfits better
- Arrowrootfits better
- Onionthe original
Fit is the average pairing score against flour, ketchup, carrot, turnip, pepper. Candidates are from the same food group and used in at least 100 recipes.
