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 oxtails
Wash and wipe the oxtails, then cut them into pieces.
Heat the butter in a pan until hot, then add the oxtail pieces and stir until browned.
Simmer the soup
Transfer the browned oxtails to a soup kettle and add the chopped vegetables.
Simmer for four hours, then remove the vegetables.
Mix the corn starch with a little water, then stir it into the soup.
Finally, stir in the port wine.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oxtails
- Provide the meat and gelatin that give the soup its body and richness.
- Butter
- Browns the oxtail pieces, adding roasted flavour before simmering.
- Port wine
- Adds sweetness and depth of flavour to the finished soup.
- Corn starch
- Thickens the soup as it is stirred in and comes to heat.
The step that matters
Browning the oxtail pieces. Browning in hot butter creates Maillard flavour compounds that carry into the broth. Pale, steamed pieces make a flatter soup, so the meat should be well coloured on all sides before it goes into the kettle.
Swap the onion
How well each one fits the dish's main ingredients (butter, clove, turnip, carrot, celery, pepper, port wine):
- Leekfits better
- Parsnipfits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against butter, clove, turnip, carrot, celery, pepper, port wine. Candidates are from the same food group and used in at least 100 recipes.
