Why it works: Carrot and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,053 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Stewed Ox-tails
Ingredients
Directions
Prepare the oxtails
Soak and wash the ox-tails well, then cut them into lengths of two or three joints.
Simmer
Cover the ox-tails with cold broth or water and bring to a boil.
Remove the scum, then add salt, pepper, onion, carrots, and parsley.
Simmer for 2 hours and 15 minutes, or until the meat is tender.
Serve
Serve with the vegetables or strain the gravy and thicken it.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ox-tails
- Provide the main meat, which becomes tender and rich through long, slow simmering.
- Carrots
- Add natural sweetness and body to the broth as they soften during simmering.
- Onion
- Adds aromatic flavour to the broth as it cooks down with the meat.
The step that matters
Removing the scum. Skimming the foam that rises after boiling removes impurities that would otherwise cloud the broth and taste bitter. Keeping the liquid at a gentle simmer afterward keeps the stew clear and the meat tender rather than tough.
Swap the onion
How well each one fits the dish's main ingredients (pepper, clove, carrot, parsley):
- Parsnipfits better

- Capsicumfits better
- Onionthe original
Fit is the average pairing score against pepper, clove, carrot, parsley. Candidates are from the same food group and used in at least 100 recipes.
