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 ↓
Ox-tail Soup a LA Jardiniere
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Cut the ox tails into pieces.
In a large pot, add the ox tails, onion, carrots, celery, bay leaf, peppercorns, and salt.
Simmer
Cover with water and bring to a boil.
Reduce heat and simmer for 3-4 hours until the meat is tender.
Finish and serve
Remove the ox tails, strain the broth, and return the broth to the pot.
Shred the meat from the bones and add it back to the soup.
Garnish with fresh parsley before serving.

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-rich bones that give the broth body and flavor.
- Onion
- Adds savory sweetness and aromatic depth to the broth as it cooks.
- Carrots
- Contribute natural sweetness and body to the broth during long simmering.
- Celery stalks
- Add aromatic, savory flavor that builds the base of the broth.
The step that matters
Keep the simmer gentle. A rolling boil toughens meat and clouds the broth. A slow simmer lets collagen in the ox tails break down gradually, leaving the meat tender and the broth clear.
Swap the onion
How well each one fits the dish's main ingredients (carrot, celery, parsley):
- Parsnipfits better

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