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
Ingredients
Directions
Prepare the meat
Cut the ox tails into lengths that fit into a frying pan.
Fry the slice of pork in a pan until the fat renders, then add the sliced onion and cook until golden.
Add the ox tails to the pan and fry, turning often until slightly browned all over.
Cut the browned ox tails into smaller sections and place them in a soup kettle with 4 quarts of water and the cooked onion.
Simmer and finish
Cook slowly for several hours, keeping the temperature at a simmer until the meat falls from the bones.
Add the sliced carrots, celery (or celery salt), parsley, and cloves, and cook until the vegetables are soft.
Season with salt, strain the soup, and add the catsup.
If desired, add the farina half an hour before serving for extra thickness.
If you dislike pork, substitute with butter.
Serve
For serving, heat the tureen with hot water and serve with crisp thin crackers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ox tails
- Release collagen and flavor into the broth as they simmer, giving body and richness to the soup.
- Pork
- Renders fat into the pan that carries flavor for browning the onion and ox tails.
- Onion
- Browns to add sweetness and savory depth to the broth.
- Farina
- Thickens the soup slightly when added near the end of cooking.
The step that matters
Browning the ox tails. Frying the ox tails until browned creates Maillard reactions that develop deeper, roasted flavor in the broth. Pale meat yields a flatter-tasting soup.
Swap the clove
How well each one fits the dish's main ingredients (pork, onion, carrot, celery, parsley, butter):
- Thymefits better
- Marjoramfits better
- Fennelfits better
- Clovethe original
Fit is the average pairing score against pork, onion, carrot, celery, parsley, butter. Candidates are from the same food group and used in at least 100 recipes.
